Question about Vizio L37 Television
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).
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.
