Question about Vizio L37 Television

1 Answer

Vizio L37hdtv10a fails to fully turn on

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.

3 flashes of the led light at the front panel is means that the unit is in booting process. The symptoms you've mentioned is caused by faulty electrolytic capacitor in the power supply section.
Look for faulty capacitor with bulged, dome at the top and then replaced it with same ratings. If you have a capacitor checker, it will make you more easy to identify the faulty capacitor without a physical indication of fault.
