Press on button and the Vizio logo turns from orange to white but no picture. It has to be unplugged to turn off. I tried "reset" and it did not work. I opened the box and see no obvious burns or damaged capacitors. The one fuse appears fine. There are a few 3.3 regulators and a couple Dpak regulators? (looks like regulators but center pin is short). The 3.3s show the right voltage but the others do not. No voltage is printed on them so I can't tell.
It's an 8 year old TV. Is it work messing with? I can solder but not sure what to troubleshoot or what the regulator voltages should be.
