Re: Vizio E70-E3 will not power up
From page 49 of the manual the regulators output is 3.39volts. Unfortunately the text is very distorted so I cannot tell how many parts are fed by 3.39volts. 3.39volts feeds a FET switch and yields 3.3volts. I'm going to pull the board, remove L201, back-feed 3 volts and see if I can get a cap to heat up or pop. Since it's not my TV and my buddy is unwilling to spend $100 for a used replacement, I'm gonna get medieval on the board.
