Hello
I have a 70" Samsung tv. It's a recent 4k model. Produced in 2020. It's barely 3 years old.
At first it was stuck in a boot loop. Something was shorting to the panel itself.
It has a power supply and an integrated t-con with a single ribbon connector to the screen which has three separate small driver boards interconnected by two ribbons.
By process of elimination i deduced the lower right driver panel was the problem.
By either covering a few pins i could get the tv to boot but the image had lines. While messing around I managed to success fully find a formula that worked to get a full 4k picture.:
Start the tv with the offending driver disconnected. Reconnect once the backlight was lit up and sound playing
After a try or two it would play for hours no problem. Try and restart and no go if you let the set rest longer than a few seconds.
I took it to a tv repair shop who just did the bare minimum and said: it's your panel. I've found a few sources that point to a bad cap on the driver board
Thing is now i can't get a picture anymore at all.
I used contact cleaner on the ribbons only sound and the backlight. Did I fry something potentially with context cleaner? It boots every time now, sound and backlight but no picture. That's what it did when I disconnected the offending driver panel... I'm thinking it's not making propper contact anymore
Hoping for advice to further fix this thing. Seems absurd to throw away
