Hello everyone, new to the forum and looking for some advice. I have a 2 year old Samsung LED TV UN55F7100. One day the screen started acting a bit crazy then went off. No picture and a lot of clicking on and off. There is sound just no picture. I called Samsung and there were no help since I was out of warranty. Offered someone to come to my home and check it out for $300 - no thanks. So I decided to try and fix the TV myself.
So I looked into the issue more. When plugged in I had no backlights or picture only sound. Since I had sound and no picture I figured it could be the T-Con board - so ordered another one for $30 and replaced it. No change.
Following that I thought it could be a power issues so ordered a power board and swapped it. No change and was able to return that. I figured the only other thing it could be was the Main board - Ordered and swapped that and again - no change. Following swapping every board I am about to give up figuring it is the panel.
Well last night I unplugged both of the cables running from the T-Con board and the panel (shown in the picture). Similar to the picture here. When I disconnected them the backlights went on. So then I connected just the left cable back in and the TV screen on the one half started working fine. The other side was all white. When I plugged in the other side the TV immediately shuts off and goes black. It does this over and over. What I am wondering is this a panel issue where its shorting out the TV, a cable issue, or anything I can do to fix this. I know if its the panel its not worth replacing. I'm just so pissed since the TV is 2 years old. I am very surprised with Samsung on this this as they have been no help. Hoping for some feedback. Thanks.
