Research Before You Open the Device

Volume 5 closed with a complete diagnostic method; this volume puts it to work on real devices, and the first skill is one the method already hinted at: for a consumer device, the diagnosis begins at a desk, not a bench. Every mainstream model arrives with a history you did not have to live — thousands of identical units have already failed in front of other technicians, and their collective experience is written down in repair forums, teardown videos, common-fault threads, and sometimes leaked or published service documentation. Ten minutes of research routinely names the likely fault before the first screw turns, reveals the hidden fastener that breaks the case of the unprepared, and locates the battery that must be disconnected before anything else is touched. This section teaches that research as a discipline rather than a browse. First the model's known world: the bench's own records and family trees where they exist, then the community's knowledge — weighed with the method's own evidence standards, because forum claims are anecdotes until a pattern repeats. Then the three documents that change everything when they exist: the service manual with its official procedures and ratings, the schematic with its circuit, and the boardview that maps the schematic onto the physical board — what each provides, where each is found, and how the bench works when none can be had. Then teardown intelligence: what a teardown guide actually tells you — fastener types and counts, hidden clips, adhesive locations, flex-cable traps, and the battery's place in the opening order. Then the research that protects: model-specific hazards, and the parts-and-price reality that decides whether this repair is worth beginning — because a teardown without a parts source is a demolition with extra steps. And finally the record: the pre-open sheet that captures what research found, feeds the family library the method taught you to keep, and sometimes delivers the most professional verdict of all — that this device, honestly assessed, should not be opened. By the end, your devices will open the way your diagnoses run: informed, deliberate, and on the record.

Section Overview

Volume 5's method meets its devices, and the first move is made at a desk: for a mainstream model, thousands of identical units have already failed in front of other technicians, and their experience is written down (the-diagnostic-method-complete). The bench's own records come first. Where a family tree, census, or recipe exists for the model, research starts there — the method's own library outranks the internet because its claims carry verifications (growing-family-trees-from-the-benchs-records). The community's knowledge comes weighed. Repair forums, common-fault threads, and teardown videos hold the model's known world — read with the method's evidence standards, because a forum claim is an anecdote until the pattern repeats across independent reports. Three documents change everything when they exist. The service manual gives official procedures and ratings, the schematic gives the circuit, and the boardview maps the schematic onto the physical board — each is hunted, and the bench works deliberately when any is missing. Teardown intelligence turns opening into a plan. A teardown guide reveals fastener types and hidden clips, adhesive locations, flex-cable traps, and the battery's place in the opening order — the difference between a teardown and a demolition (safe-diagnosis-on-powered-equipment). Hazards and parts are researched before commitment. Model-specific dangers and the parts-and-price reality decide whether this repair is worth beginning at all. And everything lands on the pre-open sheet. Findings, hazards, parts, and the go/no-go call — filed to the family library, the way the method files everything (gathering-symptoms-and-fault-history). Records first, community weighed, documents hunted, intelligence extracted, hazards and parts checked, and the sheet written — the device opens informed or not at all.

Why This Matters

The difference between a bench that researches and one that just opens is measured in broken clips, torn flexes, and repairs abandoned halfway for a part that was never available (the-diagnostic-method-complete). This matters because the community has already run your census: a model's dominant faults are usually documented within months of release — ten minutes of reading delivers what Volume 5 called a fault census, pre-built by a thousand benches (growing-family-trees-from-the-benchs-records). This matters because consumer devices are built for assembly, not repair: hidden fasteners under labels and feet, one-way clips, glued batteries, and flex cables routed across opening seams punish the unprepared — and every one of them is documented somewhere (safe-diagnosis-on-powered-equipment). It matters because the documents multiply the method: a schematic turns rail-tracing from archaeology into reading, and a boardview turns "somewhere on this board" into a test point with a name — when they exist, finding them is the highest-leverage minutes of the case. It matters because parts decide repairs before skills do: a flawless diagnosis of an unobtainable part is a completed demolition — the parts-and-price check belongs before the first screw, not after the last one. And it matters because the no-go is a professional verdict: some devices, honestly researched — serialized parts, glued assemblies, part costs above replacement — should be declined at the desk, which serves the owner better than a half-opened corpse (gathering-symptoms-and-fault-history). Research first, and the bench opens only the devices it can actually save.

Required Prerequisites

  • The Diagnostic Method, Complete — Volume 5's closer assembled the method this volume applies; research is that method's intake stage, extended to everything a model's public history can add.
  • Gathering Symptoms and Fault History — the intake discipline that frames the complaint research serves: the owner's history says what this unit did; research says what this model does.
  • A pre-open sheet template — to give the research one page to land on: known faults, documents, teardown notes, hazards, parts, go/no-go (gathering-symptoms-and-fault-history)
  • A bookmarks folder or link file per model — to keep found documents findable for the family library (growing-family-trees-from-the-benchs-records)
  • A notes column for source quality — to record whether each claim was one post or a repeated pattern
  • A parts-price snapshot — to date the availability check, because stock and prices move
  • A printed copy of the bench's no-go criteria — to make the decline a checklist rather than a mood
  • No device needs opening — this section's work is research; the screwdrivers wait for the sections that follow (the-diagnostic-method-complete)
  • A mainstream device with a real complaint — to research against something that matters
  • An obscure or unbranded device — to practise the thin-information workflow where no documents exist
  • The bench's family library, if one exists — to practise records-first research and see what the internet adds (growing-family-trees-from-the-benchs-records)
  • A device the bench already knows well — to check research findings against experience and calibrate source trust
  • Two browsers' worth of patience — document hunting rewards persistence more than cleverness

Real-World Applications

Research discipline shows up as repairs that start ahead and disasters that never happen. A technician handed a games console with a charging complaint finds the model's dominant fault documented across dozens of independent reports — a specific charging IC — and arrives at the bench with the suspect, the test points, and the part number already on the sheet (growing-family-trees-from-the-benchs-records). A repairer about to open a tablet learns from the teardown guide that the battery must be disconnected before the display flex is touched — and that two screws hide under the adhesive-mounted camera bezel, saving the case from the pry bar (safe-diagnosis-on-powered-equipment). Someone hunting documents for a laptop finds no service manual but a community boardview — and the rail names it carries turn Volume 5's power-stage walk from an hour of tracing into minutes of reading (the-diagnostic-method-complete). A bench quoting a phone repair checks parts before promising: the display assembly costs more than the phone's resale value, and the honest conversation happens at intake instead of after the teardown. And a technician researching an unfamiliar smart speaker finds three independent reports of the same power-supply failure with photos matching the owner's description — a pre-built census entry, weighed and filed (gathering-symptoms-and-fault-history). The failures this prevents: the case cracked by an undiscovered hidden screw, the flex torn because the battery order was guessed, the repair abandoned for an unobtainable part, and the hour of tracing that a found boardview would have made unnecessary.

Common Challenges

  • Community knowledge arrives unweighed. A confident forum post and a repeated, photographed pattern read the same at first glance — the difficulty is applying the method's evidence standards to sources: independent repetition upgrades an anecdote toward a census entry, confidence alone does not (the-diagnostic-method-complete).
  • Documents hide behind names. Service manuals, schematics, and boardviews are indexed by board numbers and internal model codes, not the name on the box — the difficulty is finding the device's real identifiers first, usually inside the battery door, on the regulatory label, or in the settings menu.
  • Research can become procrastination. There is always one more thread — the difficulty is the stopping rule: the pre-open sheet's fields are the scope, and when they are filled, the research is done (gathering-symptoms-and-fault-history).

Safety Notes

Risk Level: Low. This section is desk work — but it is where the next sections' physical risks get discovered, which makes hazard research the section's real safety content.

Professional Tips Before Starting

  • Find the real identifiers first. Board numbers and internal model codes unlock documents the retail name never will — battery door, regulatory label, settings menu, then search (gathering-symptoms-and-fault-history).
  • Read three sources before believing one. Independent repetition is the community's verification count — one post is an anecdote; the same fault three ways is a pattern (the-diagnostic-method-complete).
  • Time-box the research. Fifteen minutes fills a pre-open sheet for most mainstream devices — if the sheet is still empty after thirty, that emptiness is itself a finding worth recording.

The Desk Stage — Records, Community, Documents, Intelligence, and the Sheet

Recap and Frame

Volume 5's lifecycle opened every case with intake and history; this volume's devices add a stage between the history and the bench: the desk, where the model's public past is read (the-diagnostic-method-complete). A model is a family with a public census. Volume 5 taught the bench to build fault censuses from its own records; mainstream consumer devices arrive with that census pre-built by thousands of benches — unverified, unweighed, but vast (growing-family-trees-from-the-benchs-records). The research order is a priority order. Own records first, because their claims carry verifications; community knowledge second, weighed; documents third, hunted by real identifiers; teardown intelligence fourth; hazards and parts before any commitment. The evidence standards travel. The method's chain — claims needing support, patterns outranking anecdotes, sources recorded — applies to forum posts exactly as it applied to measurements (gathering-symptoms-and-fault-history). The output is one sheet. Known faults, documents found, teardown notes, hazards, parts and price, go/no-go — the pre-open sheet is the desk stage's product, and the teardown sections that follow consume it. And sometimes the sheet says stop. The honest no-go — decided at the desk, before any damage — is this section's most professional output (safe-diagnosis-on-powered-equipment). Hold the frame — a public census, a priority order, travelling standards, one sheet, and a possible stop — and the desk stage earns its place in the lifecycle.

The Known World — Records First, Community Weighed

Every mainstream model has a known world of documented failures, and reading it is the cheapest diagnosis the bench will ever run (growing-family-trees-from-the-benchs-records). The bench's own library outranks everything. A family tree, census, or recipe for the model is research already verified — the desk stage starts there, and the internet's job becomes filling the gaps. The community's forms are knowable. Repair forums and their model threads, video teardowns and their comment sections, common-fault compilations, and parts sellers' fitment notes — each form has a character: forums carry depth, videos carry visuals, compilations carry breadth, and sellers quietly reveal what breaks by what sells. Claims are weighed, not counted once. One post claiming "it's always the charging IC" is an anecdote; the same IC named across independent reports, with photos and symptoms matching, approaches a census entry — independent repetition is the community's verification count (the-diagnostic-method-complete). Symptom match is the filter. The known world is searched with this unit's complaint — the owner's history from intake — because a model's most famous fault is not necessarily this device's fault, and research serves the case, not the folklore (gathering-symptoms-and-fault-history). Findings land as hypotheses. The known world's output is a ranked suspect list for the sheet — hypotheses the bench's method will test, never verdicts to solder by, because the community's claims arrive without their evidence chains. Own records, characterized sources, weighed claims, symptom-filtered, landing as hypotheses — the known world is read in minutes and worth hours. Read what a thousand benches learned, and start the case where they finished.

The Three Documents — Manual, Schematic, Boardview

Three documents transform device work when they exist, and the hunt for them is a skill of its own (the-diagnostic-method-complete). The service manual is the official voice. Disassembly procedures, torque and adhesive specs, part numbers, safety warnings, and sometimes diagnostic flowcharts — written by the manufacturer for authorized service, and available for many models through official publication, right-to-repair disclosure requirements, or community archives — with regulatory filings adding internal photos and sometimes schematics. The schematic is the circuit. Every net, every component value, every rail name — the document that turns Volume 5's tracing methods from exploration into reading, most common for laptops, phones, and consoles through board-repair communities. The boardview is the bridge. A boardview file maps the schematic's nets onto the physical board — click a net, see every pad that carries it — turning "find where this rail surfaces" into a lookup; schematic and boardview together are the power couple of board-level repair. The hunt runs on real identifiers. Documents index by board numbers and internal codes — the motherboard's silkscreen, the label inside the battery door, the regulatory ID — and the retail name is only the key to finding those. Absence is worked, not mourned. No manual means the teardown guide substitutes; no schematic means Volume 5's methods work from the board itself — rails traced, references measured on known-good units; no boardview means the schematic plus continuity does the mapping; and a donor board stands in for all three when one is cheap (growing-family-trees-from-the-benchs-records). Legitimacy gets a moment's thought. Sources range from manufacturer-published to community-archived to grey; the bench notes provenance on the sheet and prefers official sources where they exist (gathering-symptoms-and-fault-history). Manual for procedure, schematic for circuit, boardview for the bridge, hunted by real identifiers, worked around when absent — the documents multiply everything the method does. Spend the minutes hunting; the found document repays them tenfold.

Teardown Intelligence — From Watching to Planning

A teardown guide is not entertainment; read properly, it is the difference between opening a device and breaking into it (safe-diagnosis-on-powered-equipment). The fastener map comes first. Types, counts, and lengths — the tri-point beside the Phillips, the four longer screws whose misplacement punctures a cell or cracks a board on reassembly — plus the hidden ones: under feet, labels, and adhesive-mounted trim, where the unprepared crack cases. Clips and seams have technique. Which edges release first, which clips are one-way, where the case flexes and where it snaps — the guide's pry sequence is the case's survival, and improvising it is how bezels die. Adhesive is mapped before heat. Displays, batteries, and back glass sit in adhesive with a documented location and a working temperature — the guide says where to heat and how much, and in the better guides the difference between softened and cooked is a documented temperature rather than a feel. Flex cables are the traps. Which flexes cross the opening seam, which connectors flip and which pull, and which cable tears if the halves are separated confidently — the guide's warnings here are other benches' repair bills. The battery's place in the order is the safety line. When the battery disconnects — early, and before any other connector where the design allows — is the single most important line in any teardown, and it goes on the sheet in the first position (the-diagnostic-method-complete). Watching becomes planning on paper. The guide's knowledge lands as the sheet's teardown notes: fastener map, pry sequence, adhesive spots, flex warnings, battery order — your plan, not their video (gathering-symptoms-and-fault-history). Fasteners, seams, adhesive, flexes, and the battery's order, extracted into a plan — that is teardown intelligence. Plan the opening from those who opened first, and the device survives its repair.

Hazards and Parts — The Research That Protects and Decides

Two research threads run before any commitment: what can hurt, and whether the repair can even be completed (safe-diagnosis-on-powered-equipment). Hazards are model-specific and documented. The battery's chemistry, location, and the model's swelling history; the mains-referenced sections and charge-holding capacitors in anything wall-powered; the community's paid-for warnings — the flex that tears, the shield that shorts, the screw that meets the cell — all researched at the desk, where they cost nothing. The battery report is read as a handling instruction. A model with a swollen-battery pattern is handled as if this unit's battery is swollen until proven otherwise — no prying against the cell, no heat near it, the disconnect order honoured absolutely. Parts are confirmed, not assumed. The failed part's availability, price, and source quality — original, refurbished, aftermarket — checked and dated on the sheet before the first screw, because a diagnosis of an unobtainable part is a completed demolition. Serialization and pairing are checked where they live. Some models pair parts to the board — displays, batteries, biometric assemblies — and a replacement that will never be accepted is researched as unavailable, whatever the sellers say (the-diagnostic-method-complete). The economics get one honest line. Part cost against device value, repair time against the bench's rate — not every repair is worth its own success, and the sheet says so before the teardown proves it (gathering-symptoms-and-fault-history). Donor strategy is the fallback. A cheap donor unit answers parts, documents, and known-good references at once — often the best purchase in the case (growing-family-trees-from-the-benchs-records). Hazards read as instructions, batteries presumed guilty, parts confirmed and dated, pairing checked, economics faced, donors considered — the protective research is done at the desk. Know what can hurt and what can be finished, and the bench commits with open eyes.

The Pre-Open Sheet — The Record and the Verdict

The desk stage ends the way every method stage ends: with a record — and this one carries a verdict (gathering-symptoms-and-fault-history). The sheet has fixed fields. The unit's identifiers; the complaint from intake; the known world's ranked suspects with their source weights; documents found with provenance; teardown notes — fasteners, adhesive, flex traps, battery order; hazards; parts with prices and dates; and the go/no-go. The go/no-go is the sheet's point. Go means the opening is planned, the hazards are known, and the repair can be completed if the diagnosis holds; no-go means serialized parts, unavailable components, economics upside down, or risks beyond the bench — decided at the desk, before any damage (the-diagnostic-method-complete). The no-go is delivered honestly. The owner hears what research found and why the device should not be opened here — with options: the manufacturer, a specialist, or an honest goodbye — the same honest-endings discipline the method's ladder taught. The sheet feeds the library. Filed under the model, the sheet is the family library's newest entry — the documents' links, the known faults, the teardown notes — so the model's next unit starts at a fuller desk (growing-family-trees-from-the-benchs-records). Research absence is recorded too. "No schematic found as of this date, no boardview, manual paywalled" is a finding — it saves the next case the same fruitless hour and flags the model for donor strategy (safe-diagnosis-on-powered-equipment). Fixed fields, a real verdict, honest delivery, the library fed, and even absence filed — the pre-open sheet closes the desk stage. Write the sheet, make the call, and the screwdriver — if it moves at all — moves informed.

Common Mistakes

  • Opening on the retail name's folklore. A model's most famous fault is not necessarily this unit's fault — filter the known world through this complaint, and land findings as hypotheses to test (the-diagnostic-method-complete).
  • Believing one confident post. Anecdotes with authority are still anecdotes — independent repetition is the community's verification count; weigh before you trust.
  • Hunting documents by the box name. Manuals, schematics, and boardviews index by board numbers and internal codes — find the real identifiers first: battery door, regulatory label, silkscreen (gathering-symptoms-and-fault-history).
  • Skipping the parts check until after teardown. A diagnosis of an unobtainable or serialized part is a completed demolition — availability, price, and pairing are desk-stage questions (growing-family-trees-from-the-benchs-records).
  • Leaving research in the browser. Findings that never reach the pre-open sheet protect nobody and teach no one — the sheet is the product, and it files to the library (safe-diagnosis-on-powered-equipment).

Troubleshooting Guidance

The desk stage runs records, community, documents, intelligence, hazards-and-parts, sheet. If the bench has a library entry for the model: start there — its claims carry verifications the internet cannot offer (growing-family-trees-from-the-benchs-records). If the model is mainstream: read the known world through this unit's complaint — forums for depth, videos for visuals, compilations for breadth — and weigh claims by independent repetition (the-diagnostic-method-complete). If documents will not surface: hunt by the real identifiers — board number, internal code, regulatory ID — before concluding they do not exist. If they truly do not exist: record the absence with its date, plan the workaround — donor board, known-good references, tracing — and proceed with Volume 5's methods on the board itself. If the teardown guide exists: extract it into your plan — fastener map, pry sequence, adhesive spots, flex traps, battery order first (safe-diagnosis-on-powered-equipment). If the model has a swollen-battery history: handle this unit as if its battery is swollen until proven otherwise. If the part is unavailable, serialized, or priced above sense: the go/no-go leans no — and the owner hears it honestly, with options (gathering-symptoms-and-fault-history). If the research is done: fill the sheet, make the call, file to the library — and only then reach for the screwdriver. The throughline: read what a thousand benches learned, weigh it like evidence, plan the opening from those who opened first, and let the sheet — not momentum — decide whether the device opens at all.

Verification & Testing Methods

Confirm the desk stage ran as a discipline, not a browse:

  • [ ] I researched records-first: the bench's library where it exists, then the community's known world filtered through this unit's complaint, with claims weighed by independent repetition and landed as ranked hypotheses — never verdicts.
  • [ ] I hunted the three documents by the device's real identifiers — and I can say what the service manual, the schematic, and the boardview each provide, what was found with what provenance, and what the workaround is for each one missing.
  • [ ] I extracted the teardown guide into my own plan — fastener map with hidden ones, pry sequence, adhesive locations, flex-cable traps — with the battery's disconnect order in the first position.
  • [ ] I researched the hazards as handling instructions — battery chemistry and swelling history, mains and stored-charge sections, the community's paid-for warnings — and confirmed parts availability, price, source quality, and serialization with dates before any commitment.
  • [ ] I wrote the pre-open sheet — identifiers, suspects, documents, teardown notes, hazards, parts, go/no-go — delivered any no-go honestly with options, and filed the sheet (including any recorded absences) to the family library.

Then try the practice exercises below — desk work; scenarios differ from the quiz.

Practice Exercises

  1. Read a known world (5 minutes, desk). For a mainstream device with a stated complaint, spend five minutes across two source types — a forum thread and a compilation or video — and produce a ranked three-suspect list, marking each suspect as anecdote or repeated pattern with one line of why (the-diagnostic-method-complete).
  2. Hunt the documents (5 minutes, desk). Find the same device's real identifiers — battery door, regulatory label, or settings — then hunt all three documents; record what was found with provenance, and write the one-line workaround for whichever is missing (gathering-symptoms-and-fault-history).
  3. Extract teardown intelligence (5 minutes, desk). From a teardown guide or video for the device, write the plan: fastener map including hidden ones, first-open edge and pry sequence, adhesive locations, one flex-cable trap — and the battery disconnect's place in the order, listed first (safe-diagnosis-on-powered-equipment).
  4. Make the call (5 minutes, desk). Complete the pre-open sheet: hazards as handling instructions, the failed part's availability and dated price, any serialization risk, and the go/no-go with one honest sentence you would say to the owner — then file the sheet as the model's library entry (growing-family-trees-from-the-benchs-records).

These core steps — the weighed known world, the document hunt, the extracted plan, the hazards-and-parts check, and the sheet's verdict — are tested in the Chapter Quiz at the end of this chapter, where a score of 80% is required to continue.

Key Takeaways

  • Every mainstream model arrives with a public census: the bench's own library first — its claims carry verifications — then the community's known world, filtered through this unit's complaint and weighed by independent repetition, landing as ranked hypotheses rather than verdicts (growing-family-trees-from-the-benchs-records).
  • Three documents multiply the method when they exist: the service manual for official procedures and ratings, the schematic for the circuit, and the boardview that maps nets onto the physical board — hunted by real identifiers, noted with provenance, and worked around deliberately when missing (the-diagnostic-method-complete).
  • A teardown guide read properly becomes a plan: the fastener map with its hidden screws, the pry sequence, the adhesive locations, the flex-cable traps — and the battery's disconnect order in the first position, which is the single most important line on the sheet (safe-diagnosis-on-powered-equipment).
  • Hazards and parts are desk-stage questions: the model's battery history read as a handling instruction, mains and stored-charge sections located before hands arrive, and the part's availability, price, and serialization confirmed and dated — because a diagnosis of an unobtainable part is a completed demolition.
  • The pre-open sheet is the product: identifiers, suspects, documents, teardown notes, hazards, parts, and a real go/no-go — delivered honestly, filed to the family library with even the absences recorded, so the model's next unit starts at a fuller desk (gathering-symptoms-and-fault-history).

Skills Learned

  • You can now research a model's known world — the bench's records first, then community knowledge weighed by the method's evidence standards.
  • You can now hunt the three documents — service manual, schematic, boardview — and work deliberately when any of them cannot be found.
  • You can now extract teardown intelligence — fasteners, clips, adhesive, flex traps, and the battery's place in the opening order — into a plan.
  • You can now research the hazards and the parts-and-price reality before committing to an opening.
  • You can now write the pre-open sheet — findings, hazards, parts, and the go/no-go call — and feed it to the family library.

Glossary Additions

  • service manual — the manufacturer's official repair documentation for a model: disassembly and reassembly procedures, torque and adhesive specifications, part numbers, safety warnings, electrical ratings, and sometimes diagnostic flowcharts, written for authorized service and available for many models through official publication, right-to-repair disclosure requirements, or community archives (regulatory filings add internal photos and sometimes schematics). The manual is the authoritative voice on procedure and ratings — where it conflicts with a community guide on an opening sequence or a specification, the manual generally wins — but it is indexed by internal model and board codes rather than retail names, so the hunt begins with the device's real identifiers. Where no manual can be found, the teardown guide substitutes for procedure and the bench's measured references substitute for specifications, with the absence recorded on the pre-open sheet so the next case skips the fruitless hour.
  • boardview — a file that maps a schematic's electrical nets onto the physical layout of a specific board: select a net or component and see every pad, via, and test point that carries it, turning "find where this rail surfaces" from an hour of continuity tracing into a lookup. Boardviews pair with schematics as board-level repair's power couple — the schematic says what the circuit is, the boardview says where it lives — and they circulate chiefly through board-repair communities, indexed by board number rather than retail model name. Without one, the schematic plus a continuity meter rebuilds the mapping by hand, a donor board provides a known-good physical reference, and the pre-open sheet records the absence with its date.
  • teardown guide — a community- or vendor-produced document or video showing a specific model's disassembly, read by a repair bench not as entertainment but as intelligence: the fastener map (types, counts, lengths, and the hidden ones under feet, labels, and trim), the pry sequence and one-way clips that decide whether a case survives its opening, the adhesive locations and working temperatures, the flex cables that cross opening seams and tear when halves are separated confidently, and — the single most important line — where the battery's disconnection falls in the opening order. The guide's contents are extracted onto the bench's own pre-open sheet as a plan, because watching someone else's teardown and planning your own are different acts, and the difference is measured in cracked bezels and torn flexes.
