Hello all, this is my first post to this forum. I bought a UN55D6000SF from a friend and it has horizontal (what seems to be) timing issues in the top 3-5 inches of the tv. I do have experience with fixing TV's and have had a few minutes to mess around with it and have found:
-When the T-con board is connected only to the left side of the TV (left when facing the TV) and the right side is disconnected, the left side works perfectly - and obviously the right side is black..
-I have tested a few voltages but I do not really know what to look for voltage wise - and noticed that I voltage tested a little circle called AP_SYNC and it had no voltages running through it.
First guess is obviously the t-con board but I think it could also be those boards bonded to the panel
Please give me some insight or things to try, obviously I probably need pictures (and will post them later tonight when I get home), and I dont need replies that say - "go to repair shop" haha
Well thank you all, and I look forward to helping some of you with your TV-repair related threads!
