Model # UN60JS8000 So the problem i am having is around 15-20 minutes after turning on the tv and watching a show, there is lines running down and side to side on the tv. It also gets warm on the top of the tv. It seems as when it gets warm it has the lines running down it. When I turn it off and later turn it back on when its cool it has no issue at all. I was wondering if anyone had an idea of maybe it is a cheap wire that needs to be replacing. It’s from 2016 so I wouldn’t want to invest more than $25 dollars into it. I’ve already tried opening it and disconnecting all the wiring and cleaning it. If anyone has any ideas of what it could be please let me know as it would be greatly appreciated. One thing important I would like to add is that I recently started playing switch games on it. For some reason it doesn’t really have a problem with it. After like 2 hours of gaming it has a maybe inch long black thing on it. It would eventually go away. This issue is on my fire stick and regular tv.
I’m either thinking T-Con board or main board, but heavily leaning towards the Main Board. I think the main CPU or similar is overheating. This can usually be fixed by reballing the chip, but I’m not sure how long that would last. Do you have a heat gun?
