A cracked screen, vertical lines, spreading blotches, or black while the computer still boots: these are different faults with different answers, and diagnostics separates them in minutes.
One question matters: panel only, or the whole display assembly? The technician does not decide that — the manufacturer does, in your model's service manual.
Free diagnostics: we look at your model, not at «a 15-inch».
Which part exists depends on the maker. HP states in its service manuals that «display assemblies are spared at the subcomponent level only. Entire display hinge-ups are not spared»: on those machines the full assembly does not exist as a part. Lenovo lists the panel as a standalone FRU on ThinkPads. Dell publishes a dedicated panel-only removal procedure on several lines.
Touch changes everything, in writing. HP: «touch displays are spared only as the entire hinge-up. Non-touch displays are spared only at the subcomponent level». Touch glass and panel are laminated together and the digitizer has its own cable. On a touch laptop, «just the glass» is not a cheaper option: it is not an option.
Something repeated online that is not true. «30-pin and 40-pin are two eDP standards» and «40 pins means touch». VESA's own eDP publications contain no physical connector and no pin count for notebook panels: those are panel-maker conventions, not standard variants.
Hence the need for an exact match: pin count and pinout, connector position, native resolution, refresh rate, backlight type, brackets and thickness. There is no «15.6-inch panel»: there is your model's panel, with a part number.
| How the maker supplies the part | panel only, or assembly only — it varies by model |
|---|---|
| Touch or not | on touch, many makers supply the full assembly only |
| Panel match | pins, pinout, resolution, refresh, backlight, brackets |
| Hinges involved | if a stiff hinge cracked the glass, the hinge has to be sorted too |
| Cable or board | a black screen is not necessarily the panel: we check first |
| Part availability | depends on the model code, not the screen size |
The factors that actually move the cost of this job. They are not our rules: they depend on how the manufacturer supplies the part, and they are checked at the diagnosis stage before anything is ordered.
