Samsung UN70NU6070F
Picked this tv up off marketplace for 50 Canadian coins.
Old owners say it got darker and one day just died. If you plug it in it will power cycle non stop. I opened the tv up and if you unplug mb from power supply backlight will turn on and stay on. As soon as you plug in mb it will power cycle again.
Next thing I tried was unplugging the long flat cable from bottom of tv. Doing this and waiting to plug back in will make it so that I can get a picture and sound.
Next thing I tried was unplugging this long cable again and leaving unplugged. I was able to play audio with no picture.
When it powers on it looks great, no weird lines or anything. If I can get it to stay on what a steal lol.
What should I look for? Bad tcon board? Bad power supply? Bad mb? I'm more lost than ever
