Hey guys,
I have a Vizio E552VLE that I'm currently trying to fix. The symptoms are that the TV will not turn on. There is no Vizio light illuminated on the front when plugged in. It just went out one day and didn't turn back on or so I'm told.
Well, troubleshooting this TV has got me at a bit of a loss. The fuses are fine on the power supply board which is an 0500-0513-1140 (N312A001L). This was my first idea seeing as there is no Vizio light in the front. When testing voltages on the board there are 5V+ there to the main board but no other voltages from the connector are present even when the power button is pushed. I did check the other connectors for shorts (not the same one that goes to the main board but the T-con boards?) seems okay? A resistance reading of ground to the 12V on those connectors increase in resistance?
The main board is a 3655-0422-0150 (0171-2272-4314). It is getting the 5V and the fuses are fine there as well. I'm assuming the main board is bad because there is no remote V to the power supply when the power button is pushed. The Vizio light on the front also goes through the main board which furthers my suspicions.
Problem being is I'm having trouble trying to find a main board for this TV IF that is the problem. Any guidance would be appreciated. I will take pictures as soon as I can.
