Question about Vizio L32 32 in. LCD HDTV
On the power supply board there will be a connector that says PO which means power on from the main board. Make sure that goes High when you press the power button. Make sure your stby voltages are ok on the PS. If the PO goes High then the power supply needs repaired. A lot of the ic's on these boards are not available for us to buy, so you have to replace the board. If it doesn't go high then the main board is at fault, gets a little more tricky with that, but not impossible.
