Vizio e320vl standby voltage 6.28v no 12v supply

[danilodiaz9]

Hi,
I have a Vizio e320vl lcd tv and I get an amber light but when you push power button it does nothing. My guess is power supply is good but main board is bad. I need some help with power on circuit. I do show 6.28v on standby but no 12v even when you press power button. Thank you in advance!

First, you better check the batteries of the meter.
Second, we need the pictures of the whole backside of the TV showing all the board.

Ok, so did you check batteries of the meter?
We have to make sure the batteries are OK first, then we need to check the DCV of all the pins of the connector of the power supply board that goes to the main board to find out what are missing.
