To get a service manual. The TCON board is what I see folk that read the internet try all the time. You need a service manual, basic tech gear and not be new to TV repair. You also know TV repair discussions are very rare.
I have a Samsung UN55H8000 and get sound, but no picture. I changed out the TCon board, but still nothing. When I turn on the tv, the picture came on, then half of it went, and then it all went. I was able to reset the tv, but still nothing. I unplugged it for about 12 hours, and still nothing. Any suggestions would be appreciated.
