- Topic title should contain: the device's manufacturer, full model and the brief description of problem.
- Topic message should contain: the PCB marking code (required in case of hardware repairs), an extended description of problem, things you have checked/replaced/measured, your conclusions and the question. If you are not able to find the PCB marking code, please read THIS TOPIC. If you still cannot locate the PCB markings, please upload a clean, both-side photos of the mainboard - it is required to remove any films, modules or brackets possibly covering these markings.
- Before posting a new topic please read all topics in TRAININGS subforum and make a preliminary diagnostic based on the content of those trainings.
- Uploading of any complete schematics, BIOS / firmware files or any other kind of documentation, or linking to 3rd party websites with such files, is STRICTLY PROHIBITED. You can only upload the small portion of documentation or, link to BIOS file on UNVERIFIED BIOS FILES subforum, which simplifies the diagnostics/repair. You are not allowed to upload more then one complete page of instruction/schematic per single topic. The file you upload must not contain any watermarks, "confidential" markings, links or email addresses and cannot be password-protected.
- It is only permitted to describe one faulty device per single topic - you should always open a new topic for each subsequent device.
- Requesting of the full schematics, BoardView files, BIOS files or any other kind of documentation is NOT ALLOWED in this subforum. If you need to ask for any of these, you should open a new topic in DOCUMENTATION/BIOS REQUEST subforum.

Ok, padły mi w końcu podświetlanie więc musiałem rozebrać, klej polecam jakiś odrobine chociaż plastyczny, przezroczysty, poprzyklejałem, wymieniłem 8 ledów i działa ok.
Pytanie jeszcze następne. LEDy kończą swój żywot generalnie więc zamówiłem nowe paski, bo stare już 6 lat a TV gra 18 godzin dziennie. Czy wymieniać profilaktycznie drivery do nich przy okazji? Płyta opalona delikatnie naokoło, ale póki co działają, napięcia w normie.

LED diodes in the TV backlight usually die due to excessive electrical current flow through them, which in combination with a poor cooling causes them to overheat.
In such a case, after replacing the LEDs, I also reduce the current through them by about 10% by replacing the current sense resistors in LED driver. The picture is a bit darker on this account, but this is almost not noticeable. The LEDs therefore heat up less and consequently last longer.
I think there is no need to replace the driver chips.
