VIZIO XVT3D474SV Black Screen and Moving Lines?

I have a Vizio XVT3D474SV that I purchased in 2011. This weekend, it started acting up. The screen goes black, horizontal black and white lines appear (moving) and vertical bands of color come and go. There's also a buzzing sound through my sound bar. This happens after the tv has been on for about 10 minutes. I turn it off and am able to turn it back on after five or so minutes, but then it happens again. The sound continues and the input does not matter. I've checked all of the connections.

Does anyone have a suggestion as to what needs to be repaired/replaced?

I have this same TV model but I have no problems. Since the symptoms happen after a warm up, I suspect the power supply, because I have seen similar symptoms on a different TV brand.. One of the voltages has dropped, causing this massive failure in display, signals, and audio. The power off period allows the supply to cool off, but returns after the warm up.

If you don't have the resources to check and replace the power supply, go to a professional technician.
