VIZIO TV Black screen. Cannot turn off TV without unplugging.


I had a similar problem after having a Vizio for 2 and a half years. I left the room for a minute, i came back and the screen went black. I didnt hear an arcing sound though. There was still power to the unit and you could see that the back light was working, just no picture, no sound, and you couldn't use any of the buttons. The only way to turn it off was to unplug it. It would then start up, with the Vizio logo going from orange to white, and then do the same thing all over, no pic or sound. I would check the ceramic fuse first on the board that gets power from the plug.

HOW I FIXED MINE: I ordered a new "main PCB" from tigerdirectparts.com (you can also use searspartsdirect.com). This is the circuit board with all of the inputs on it (hdmi, cable, etc.) I opened it up, disconnected the old one, put in a new one and now it works fine.I used both serial numbers on the board to search for it online. It cost me $144 to do it, but that's better than $450 for a new TV. My tv is the vx32l hdtv10a. I hope that helps.

It started with no sound,I unplugged,then plugged tv backup got sound for awhile than everything went black could not even turn tv off but the vizio sign stayed blue


Theres a logic problem between the interface board and power supply. This is very common in Vizio's. There's a square wave start code that's not being generated properly form the processor to logic functions then power control. There's no 'read/write_code' available too ROM therefore power on/off commands are absent... this could also affect inverter control functions.

If its under warranty take it back, or have a local shop fix the tv for you.....

Black screen


Most likely the TV has a power supply related problem. It's possible that it maybe a bad capacitor or transformer on the power supply board. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
But, I can't say it's 100% the problem because I can't actually look at the tv over the internet.

I would keep hounding them for the warranty issue. Why do you have to spend a dime if the TV is still under warranty? I would just keep at it.


I hope I shed some light on the subject for you.
