Vizio LCD 37 Inch Turns Off Randomly

I have a 2006 Vizio 37 inch LCD that has started to turn itself off randomly.

Sometimes its within a few seconds of me turning it on, other times its hours into the TV being on. Sometimes it turns off once and then is fine and other times it will turn itself off several times in a row.

I called Vizio and, of course, my warranty has expired. I reset the TV per their instructions and have changed power sources, but am still having the problem.

Anyone have any solutions for this? Thanks, in advance, for any help you can provide! i have a l 37 vizio that keeps turning off by itself i took it back to the place i bought it from but they said they would have to run it all weekend is there any one that can offer me or them any advice?

    Same problem, has been going on for 6 months, sometimes 15 times in a row, then no problem for weeks.

    32" Vizio LCD manufactured 2006. Randomly turns itself. Starting to get more and more frequent. Maybe had the t.v. for a little over 1.5 years. Was impressed with Vizio but probably not gonna buy another one.

This could be a main board or power board issue. replacing main board and/or power board should resolve this problem.

Solution: A new wifi extender, or a new or reset wireless modem or router in the range of the TV will cause this problem. Disconnect the TV from wifi, then reconnect manually and this will solve the problem. If you are not comfortable manually setting up the wifi connection you can reset the TV to factory settings and go through the setup process but you will also need to re-program the remote control again. (look in your manual to find instructions).

Yep i replaced the main board for about $120 and all is good. Easy fix, even a caveman could do it.

One of the driver IC'S has gone bad. Need to replace just the driver IC or the board that the IC is on and that should solve your problem. If that doesn't do it, then the BAD NEWS IS THAT THE PANEL IS BAD. Replacement is you only option then. Good luck. GURU JAY.

Vizio LCD 37 Inch Turns Off Randomly


I had a similar problem with my 32 inch plasma tv. I called vizio's
1 800 number and the guy said to unplug the tv from the wall and hold down the power button for a minute and then plug the tv back in outlet and turn on. And it works I guess from what I understood from his heavy accent was that the tv retains power and this resets it somehow. hope that was helpfull!!
