There is a Samsung UN50NU7100 panel being sold in my neck of the woods for cheap ($40). And there are all sorts of broken screen 50" smart tv's available for cheap or free. In fact, someone is giving away a 50" 4K TCL with a crack screen. Since both the un50nu7100 panel and the TCL tv are 4K, can I just put the un50nu7100 panel in the TCL?

Re: Can I use a Samsung 4K LCD panel in a 4K TCL TV?
Likely not compatible. Though some brands use the same panel, odds of random TVs with same panel are close to zero. If they use the same tcon board, they use the same panel but newer models don't have tcon boards. -

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.... -
Well, I will be the first to admit that I screwed up...
In attempting to replace the backlight in a UN65TU8000, I made a hole through one of the ribbon cables between the board that runs along the bottom of the back of the TV and the panel. This lead to a between a 1/4 to 1/2 inch vertical stripe running the full height of the image.
I don't have the experience; personally, to solder a bridging wire for the paths that were cut. So, I have been on the hunt for other Samsung TV's of similar size.
I have 2 that I have found and have in my possession. ... -
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 was given this Samsung GU50TU8079U that would power cycle after a couple seconds, sometimes a few minutes. The screen would turned cloudy dark with the backlight still lit and then the sytem would restart.
Its one of the newer screwless Samsung models that I read a lot about panel failures here. It does not have a sperate T-CON board, just one ribon from the mainboard to the panel board and a U-shaped ribbon cable connecting the other half.
I went through the usual diagnostics:
unplugged the mainboard -> tv stayed on
removed the U-Shape robbon ->...
