    Vizio Plays for about 20 Minutes and Makes a pop and has stricks or white lines going vertical on the screen and cuts out the sound, but the picture is still showing, and moving, I have to unplug the cord and plug it back up and it will start right back playing for another 20 minutes and does the same thing. I Took the back off and was going to change the main board and the board i purchase was bad, so i put the old board back in and let it play with the back off and it play for 3 hours until i put the cover back on, and it started doing the same thing. I don't think the cover is touching anything to make it ground out. Please help me solve this. Thanks

Where can I order the small component board with the switches for the VIZIO L32 HDTV? I have found my problem the switch is corroded and jammed due to my sister in laws cat! I have determined no other damage but the input switch and the contactor for the remote sensor. I have also placed a plexigalss barrier to prevent further damage. Oh the things you get into for family!

Leadtech described how to remove the back panel. However, after removing all the screws the panel does not easily come off. Do you need to pry off the back panel?

As long as you know how to use a screw gun or drill, then, you will be able to replace the main PCB. There are only two main boards in this set, the main and the power supply. To remove the back, take off the stand (if it is on a stand), usually held on by four screws. Place the set face down (on a soft towel or blanket) to work on it. Remove the back and you may find a large shield covering the main and/or the power supply. The rest is up to you. You'll be fine, any help just respond to this solution and it will contact me.

Vizio TV wont turn on after three weeks no use

My vizio recently did the same exact thing. Vizio sent an HDTV tech out to fix it and it was the power board. He put a new board in (took 15 min) and the tv works like new.

My Vizio L32 periodically turns itself off, multiple time a day.

My 42" and 32" started doing that, I bought it form Costco, they set me up with Vizio under warrarnty. A tech came out and changed out the circuit boards, but the problem persisted, they are now going to send me a reburbished replacement. I'm not Happy, they should send me a new non defective one(actually 2). I will not be buying any more Vizios!

Vizio L32 TV won't turn on. yellow power light lit, should turn to green when button or remote is pressed, and set should come on. No response to either remote or manual buttons. No change after unplugging...

Had same prob;em. Replace main board and now works just fine. You need to take the back off and under the metal cover is the main board. The part number should start with 3320-xxxx-xxxx. You can purchase the board from Vance Baldwin. sign in as a guest. I will warn you the cost of the board is high.
