I have a Vizio M502I-B1, turns on, works great for about 15 minutes, then the screen freezes. Sometimes, it will automatically power off and back on after the screen freezes. The audio always continues. Powering the TV off and back on solves this issue temporarily for about 5-10 minutes, then, it will continuesly freeze every 5-10 minutes after that,

I'm assuming a component is overheating and this is causing the freezing. What I'm trying to figure out, is which part is most likely causing this? The LED Driver Board, The Main Board or the Power Supply Board?

I'm leaning towards a replacement of the Main Board most likely will solve this, but I'd appreciate the insight from an experienced tech,

Any insight is greatly appreciated, Thanks,

you could get heat to some chips and have a look if it reacts earlier than 15min.
or you could cool some chips (freeze spray for electronics) of one board and have a look if it doesn´t freeze the screen after 20min
