Well it's heat related so that's good. Heat gun and freeze spray are your friends here. But may just be bad connector. Remove and reseat all connectors, especially at t-con and panel. Mainboard to t-con.

Yes I reseated all connectors on power supply, main board and tcon. still does it after an hour or so.

When tv cold, take heat gun and start going over one board at a time. See if you can replicate the problem.

Right now i have a fan blowing at the power supply, tv has being on for about an hour, good so far.
