Question about Vizio L32 32 in. LCD HDTV

6 Answers

Television Powers Off While Watching then turns right bcak on if we hit the power button (or stays off if we do no). Happens randomly. It can stay on for hours and not turn off or be on for 5 minutes and turn off. As you can imagine, it's frustrating. Vizio support not helpful as I'm not under warranty. No other problems with this 1.5 year old set. Thank you for any insight. B

    My 32" LCD Vizio set turns off on its own while watching a movie or show then pops back on again very annoying.

    My 42" Vizio plasma was doing the same thing, powering off when it felt like it. Now it has quit except for the orange light in the lower R.H. corner.

    If I unplug and replug it in, it clicks twice but no function. Any ideas?

    Brand new 42" Vizio right out of box turns off randomly, when I keep turning it back on the intervals that it stays on get shorter and shorter. Is it possibly getting to hot and shutting itself off? EXTREMELY annoying.

    My Vizio 32" LCD tv started turning off on its own, then would come back on by itself after about 30 seconds. Now it will not power up at all.

    Does anyone know what the fix is for this?

  • wmslawyer Jun 02, 2008

    my vizio L32 continually powered off while wacthing then always came back on. It was just a nuisance at first but now it will not come on at all. Is this a problem that is fixable . I note that many people seem to be having the identical problem. Should I just rhow this TV int he garbage or is it worth fixing and how to I accomplish the fix.

    Same with mine. Just turns itself off and then back on in 30 sec. Now it won't power up at all. Is it the power supply? Where is the switching done? No browning on board or cold solder joints visible.

My L32 HDTV10A was doing the same thing, and finally stopped coming on altogether. I got to Level II vizio Support thinking it was the Power Supply board, but the guy there told me this problem is usually the Main Board. Vance Baldwin is the electronics parts distributor for Vizio. Try website or call them with your model and serial number at 800-432-8542. Mainboard about $150 Power Supply Board about $50

Need a new schematic for this vizio L32HDTV, that blew power supply board. The problem started with black squares on the TV, followed by the TV powering off, prior to the TV sparking days later.

The green light merely indicates that power is getting to your TV. The symptoms you describe point to internal power supply failure
