Vizio VW32L HDTV10A No Picture and No Sound

[Jimmy60]

Looking for a little help on my Vizio 32" flat screen. When I plug it in the standby light comes on lighting the VIZIO insignia amber. When I hit the power on button on the remote or on the tv buttons, the VIZIO insignia turns white and the back light comes on but there is no picture or sound. I have removed the back cover, check voltages from power supply and not found any problems or visible damage. I believe the problem is most likely in the main board since there is no sound or picture but not sure how to determine for certain before going any farther. I am able to replace electronic components on the pcbs if I can figure out which ones are bad?
Thanks in advance for any help you can give.
