Question about Vizio L32 32 in. LCD HDTV
We have a dark gray wavy shadow on the right side of our vizio 32" screen. It started as an irregular vertical wave approximately 2" x 8" and has grown and darkened to cover nearly 1/3 of the right hand side of the screen. It is most visible when the picture is a bright background especially white.
Go to Vizio website and buy the extending warranty, you need to have your TV replaced since the problem is with the screen itself.

SOURCE: Vertical Red Line
I had a bright red 1" wide vertical line on the right side of my Vizio P42HDE as well as an equivalent Green line on the left. Sometimes a Blue line would appear adjacent to the red line. Had this TV sinc Oct. 2005. Based on internet research, I opted to purchase an LG 6871QCH060Q board (upgrade to the 6871QCH038A and the 6871QCH038C). Picked the board up on Ebay for $100 + $10 shipping from ShopJimmy parts.
From start to finish, this took about 2 hours to repair. Tons of screws to remove. Took me a while to figure out that the video connection unit in the back is completely modular and needs to be removed before attempting to remove the back cover. Once the cover was removed, I was surprised that I could not see where the replacement board was located. Turns out, you have to go one level deeper and remove the audio board and digital board followed by metal bracket/cover. Once removing the metal cover, the bad 6871QCH038A board was visible. A couple of zip ties will need to be cut as well as several cable connections to get to the 6871QCH038A board. Replaced the board with the 6871QCH060Q upgrade. Make sure to keep the sticky foam rubber isolation pieces and adhere them to the new board. It did take some time to figure out how to disconnect and reconnect all the various types of cable connections. Just take your time. The power cable connector for the 6871QCH060Q board is in a different location, thus I had to reroute the cable. Reassembled and only had 2 unused screws left!
TV workd great. Lines are gone. Have a little burn-in going on where the red line appeared, but still better than forking over $800 for a new 42" LCD 1080P TV. Hope to get a couple of more years out of this Vizio.
One line I found has a general example of LG/Vizio repair manual. Not exact, but close enough...http://www.scribd.com/doc/7580885/LG-TV-Plasma-Training-Manual

This may work for you. My Vizio went black except for the blue channel rectangle in upper right corner; I couldn't change the channels or power off. I called Vizio, was told I needed a hard reset, and this fixed my problem: I unplugged the TV; held down the on button for one minute, then plugged it back in. It works fine now.

This could be several things. It could be the main board 3850-0042-0150 or the plasma controller board 6871QCH083A.
Depending on what you actually see on the screen it may as well be bad Y sustain board (although less likely).
Unless someone has seen that particular issue in that particular model (or other that share the same deffective component) it will be anyone's guess which is the exact module. They all can be causing what you describe.
Since TV shuts itself in one minute I'm leaning towards the main board.
I'm afraid you'd have to either experiment or bring it to a service center that will either have such a TV and can try or will experiment on your behalf. Just make sure you do not pay for boards they experiment with. I know some of the other TV service shops in our area (and without a doubt elsewhere too) do that.
A TV service center (just as anyone with regular contacts with eBay) can resell incorrectly ordered part and end up losing $10-$20 on it which , if split between customer and technician, I think is completely fair. Just make sure you don't end up paying for a board that was ordered and turned up not the one in fault.

If half screen is affected it will be either a board (LCD and Plasma have different names) but in those one board drives each side of the screen unit--worst case is the display panel itself which is fatal from a cost point of view.
