vizio plasma works for few mins then pops off

[bigred*]

So I fixed this tv about a year ago, it had the infamous pop of death and fried some video boards when it went, replaced the boards, and all the bad caps on the power supply, its been working great for about a year now but, it just popped off on me again, no loud pop from a cap going, just went all black, sound is gone also, so no video or sound, the little light at the bottom stayed green though, turned it off and unplugged it, let it sit for a couple min turned it back on and it worked perfect for like 5 min before everything popped off again, I'm afraid I've got a cap going or something so I don't want to keep turning it back on, I'd rather fix the problem before it blows taking other stuff with it.. what should I do, and/or look for? Could it be tempature related? Cuz its like 50 degrees in this stupid house

If its a cap that's going would it already be bulging? And just hasn't completly gone yet?

Pic of boards and one of entire back of chassis so we can see what we are dealing with... Good lighting with the flash turned off.

Is "pop" coming from speakers? Could be AC detect fault.

DO you have model #? Pops can be Caps or (what I have experienced) IPMs. Glorious, glorious IPMs.
