Vizio V555-G1 stuck on wallpaper; now stuck on V logo

The tv is currently in my garage which has been about 32F the last few days. I work in there and it's not heated when I'm not in there. Would that have anything to do with it?

noise which i mean... we have 12V to T-con... but the currents not enough to handle whole screen... so in this case the 12V T-CON 12VCC CAPS are fault need to change.

I haven't had a chance to look into this yet, but the other night I turned it on and the bottom half was black with white horizontal lines, and last night the entire screen was black with white horizontal lines going straight down the center spanning about 2/3 of the screen. I'm thinking it's gone into full tcon failure at this point. I'm guessing the caps on it would be surface mount? I do have the means to replace them now, but if it's too many a new tcon would probably be worth it.

can you tell the 12V T-CION VCC coming from Power boards or Main boards? need photo of the t-con and the source of the 12V T-CON

It's about 40F today and I plugged it in to what it would look like. It only had about a 1 inch bar across the bottom this time, and like before it slowing moved down and off the screen. I put a heater on the power supply and unplugged the tv to see if it would come back. It did not come back. I'm thinking of taking it inside my house and letting it sit at room temperature. I have a feeling it would work fine in normal temperatures, although that still wouldn't be a "fix".

Attached are photos of the boards. I did clean the ribbons and well.

Heating up the power supply definitely gets rid of the issue. So does this mean there's something wrong on the power supply, or bad caps on the TCON?
