Yea, I'll find a parts TV I'm sure within a month that has something I want to mess with. I'll post results if I have time. Currently I got 17 tvs in the garage and I need to get the parts and get em sold! But I keep looking daily for something with a problem like this. Not super common

I have a 50" Toshiba bezel-less that I replaced backlights in a few weeks ago. The tape didn't hold well so the panel started hanging from the top. The pressure caused the two bottom corners to shear off. I can see a court contact on the right corner, but the left is gone in assuming. The screen is not cracked anywhere else, but it displays no image.
Is it at all repairable? I'm assuming not.... -
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... -
Hi, all
I need the dump/firmware for this tv, it was on a boot loop, i dont have the original corrupted dump because i used a pen drive with a firmware that solved the boot loop, initially it seemed it was ok but the tv has no sound

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 had a the above tv qn55q60r that had a bad panel but everything else good. I had another panel here from un55nu6900 with bad leds and melted diffusers.
I put the nu6900 panel in and powered it up and it does work but there are lines vertical lines.
I was trying to change the panel type in the service menu but don’t see my exact panel. Anyway to fix this or someone have similar experience.
the clear picture is the panel type from the service menus on the nu6900. The other 1 is the panel type that was set for the q60r with the bad panel....01-13-2024, 01:57 PM
