Samsung LED flat screen TV: No power to backlights even after power supply board swap

Sat, 19 Aug 2023 16:08:51 -0700

Have a samsung un55fh6200fxza 55 inch led TV that I've replaced the power supply board led interface strip and all leds and still no light. Screen shows image but I can only see it with a flashlight pointed directly at the screen. What else can be the problem?

Samsung LED flat screen TV: Q80 TV Screen Flashing when One Connect Box Overheat

Sat, 03 Jan 2026 05:19:34 -0700

The screen of my TV starts flashing after power on for about 20 minutes. When I turn on the air con to lower the room temperature, the situation gets much better.

I then removed the case of the One Connect Box to help dissipate the heat, and it can also ease the flashing problem. That’s why I’m pretty sure the cause of the problem is overheating.

If overheating is the cause, what are the heat sensitive electronics that could cause the screen flashing (transistors, capacitors, etc.)? Any suggestion I can narrow down the cause? Thanks.

Samsung LED flat screen TV: Samsung un55js700df diffuser panel order

Tue, 11 Apr 2023 08:57:34 -0700

I replaced the backlights on my Samsung LED TV un55js700df and needed to clean the plastic diffuser sheets of some kind of oily substance that showed up on the display. During the time it took to receive the LED backlights I forgot the order the diffuser sheets were in and can find no reference to this on line. Does anyone know what the order and side of the hard white, soft white translucent, silver, clear purpleish panels go in?
