Re: tv screen flickering on insignia 43 inch
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.

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