I have a VW42LHDTV10A Vizio, no picture no sound, no response from the remote or the buttons on the set. Have to unplug to turn off, My back lights are coming on and I get a white screen now that I replaced Two voltage regulators U7 and U33, Both fuses F1 & F2 are good. I am safe in thinking it is just a main board problem or could the inverters be bad. Can't find a service manual for it so I don't know how to test the inverters. Can anyone help??
