Hisence 65U6G I have ordered all of the boards in a kit from shopjimmy however while swapping left and right T-Con output cables I noticed one had a burned trace. I flipped the cable end for end and it burned another trace on the same connector PIN number. I have now also ordered new 60 pin cables. My concern is I can not determine if the problem is with the panel, T-Con, or something upstream of the T-Con board. Maybe someone can help with a schematic? The T-Con part number is 290410. I really hate firing the parts cannon without a clear target. Thanks, Bill
Bad news for me. I have replaced everything except the display. Powered it up and had a full picture for a couple of minutes. Unfortunately the picture faded away to be replaced by a white screen. I disconnected the left T-con to display ribbon cable and have a perfect picture on the right 1/2. I think at this point it is safe to assume the left display is bad. With that I’ve reached the end. Thanks @oldturkey03 for your time.
@bbm2c this is very difficult to determine. You are doing the right thing by replacing the T-con board as well as the cables. Sometimes flipping them can actually cause more issues. Anyhow, you are more likely having issues with the T-con board vs the panel. Since the LCD driver board(s) seldom are the cause but often the result of a short circuit. It might help if you try and get us some pictures of those boards. That way we can see what you see. Somebody may see something….Adding images to an existing question - iFixit Repair Guide Schematics are pretty much non-existent in the public domain. So, we are on our own trying to fix this.
