Re: VIZIO VX37L: Backlight shuts off after a few minutes of use

The Power Supply still stopped sending the 12 and 24 volts to the main an inverter boards after few minutes of use.

Re: Vizio VW37 Power Supply PSON working but no 12v or 24v output

Hi everyone,

I have a VIZIO WX37L and two days ago it stopped working. The problem is very similar to Tetranitrate’s. When the TV is plugged in the VIZIO logo glows orange. Turning the TV on will result in the VIZIO logo turning white (however, no sound and no image). Two or three seconds later the VIZIO logo glows orange again. At first glance, I look the power board (Part#0500-0505-0420) for bad caps but all of them since to be OK.

Tetranitrate: What is the status of your issue?
