I had to replace the led strip in one of these edge lit led tv's. I'm trying to put this tv back together but unfortunately the diffuser panels got all mixed up and I really learnt a lesson on this one. If anybody knows how to put these diffusers on the right way please help. I have put this tv back together like 10 times and close to giving up.

Re: lg-55UH6090 Diffuser panel mixup
Ya I fixed this through days and days of giving up and restarting it. Their is no easy way of doing this other than trial and error and yes its a major pain in the ass. The school of hard knock taught me to never ever mix up tv diffuser layer ever again lul sorry man just keep trying different orientations.Comment

49UJ6500 LCD panel has a lighter band on top when first powered on. Goes away (or gets much fainter) after TV on for a few min. After powered off for awhile and power back on, same band appears. If powered on immediately after powering off, no or much fainter band. Running the latest firmware.
Disassembled the TV and lifted the LCD panel during testing. Band is on the LCD panel (can see the band on the panel as I lift it slightly) Backlight is perfectly even at the top edge. Double checked LCD panel alignment in the frame and is perfect but since band moved with the panel, its on... -
TV flashes backlight then reboots over and over. no image. Client said it used to have image for a bit before rebooting. Got worse over time.
tcon is built into mainboard.
Only one cable goes to panel boards.
there is a cable from one panel board to the other that links them.
cost cutting measure that results in us having harder time to diagnose.
removing the link to the second panel board allows TV to stay on with stable backlight but no image.
used cut off tape method to mask 1 maybe 2 pins on the side of the cable that goes to that second panel board.... -
I have a TCL 55P6US with sound and backlight but no picture. This model does not have a T-CON board, and the right (rear perspective) panel board is fed from the left panel board. I have not been able to induce any change by disconnecting the secondary panel board or the tape cut-off method on the primary board.
There are a bunch of voltages missing on the panel boards. I can't find any shorted caps of the panel boards, and all of the missing voltage rails read in the kiloohms, which leads me to suspect the issue may lie on the circuit board, rather than a short in the panel.

I came across a 50inch TU8000 that wouldnt start up properly (blinking stand-by light, backlights would cycle on and off).
When i opened it up and removed the power to the mainboard the backlights powered up and everything looked uniform.
When reconnected the mainboard but disconnected the flex cable to the panel i heard the TV startup with the intro sound.
Later I checked for shorts on the panel PCB boards but could not find anything.
When I took a look with the FLIR i noticed the 2 resistors...08-10-2024, 08:39 AM -
Hello,
I'm trying to repair a UE50NU7022KXXH with a cracked diffuser/lpg and now also with burned leds
There are 4/5 white spots on the bottom that are not visible since the left side is dark now so I want to change the diffuser/lpg
Looking the samsung spare parts, I see that there is a DIFFUSER PLATE and a LPG so I'm wondering what is really broken?
