any recommendation on purchasing a replacement sv420m mainboard?
Read of all the messages on this vizio tv in this forum, seems best bet for my repair is a new working sv420m mainboard. the symptom just like bigkerrdogg mentioned in the forum. +12 is present upon plug-in. led in amber all the time. no response to power-switch. Power-board tested good. any ideas, suggestions are welcome. -

any updates? I've got one with exact same situation. Guess it's the main board problem. But I don't like to order one from ebay for over $50. any help is appreciated.Last edited by vicwang; 11-23-2013, 05:56 AM. -
Any idea where to download the zu.runs? I've spent quite sometime on it, all failed so far :-(
Thanks,
