I have a Vizio E470VL that will not power on. I have replaced both the power supply board and the main board with new ones. Still the same result, only the orange vizio light comes on when plugged in, and dims down immediately. I replaced the power supply board first (0500-0412-1000) and that did not work. Then replaced the main board(3647-0292-0150) and that did not work.
I ordered the power board from buyqual.com and they sent me a different board (0500-0412-1210) that looks exactly the same as the original. I have spent $250 on boards so far and still no luck. Any help would be appreciated....
