Symptoms, when power button is pressed status led changes from amber to green for ~1 second then reverts to amber. The back light never turns on. Now I know I have a good power supply, I checked that its supplying 24V to both inverters, and 12Vand 5V to the main board. I think I have to replace the main board(DTV, mother, I/O depending on who you ask) its a 3370-0072-0150. But the question is it the main board or is the main board just failing to start because an inverter is blown(this tv used to be a demo unit at sam's club).

Re: Vizio L37hdtv10a fails to fully turn on
You will have to isolate the main board and Inverters. Unplug the inverters and turn on the set. If it "turns on" then try re-connecting each inverter seperately to see if only one is causing the problem.

Interesting, sound like a failure of the button because most system either work with a greeg lit up led or fail with an amber or orange lit or flashing. In this instance the amber could mean something has gone bad but the fact you can hold the button and have it boot up is strange.
Does the led turn green after holding the button for a while to let the machine boot?
