After a brief power outage my TV won't turn on. The power comes on and the Vizio logo flashes orange/white but the TV is non responsive. I powered cycled it and that worked so I bought a UPC just in case the power goes out again. When I plugged the TV into it the same problem occured only this time power cycling had no effect.
I bought a Vizio 0500-0407-0910 used Power Supply and installed it and that seemed to fix it. So I unplugged it to put the rear cover and stand back on. when I plugged it in the same problem recurred. So apparently unplugging the TV is what causes the problem. Which I could live with if only I could get it to come on one more time. I would just leave the back cover off and never unplug it again. There is a fuse on the Power Supply board (I marked it) and I wonder if replacing it or even just jumping it might get the TV to come once more. I attached images of the Power Supply board and the Main Board.
