Question about Vizio L32 32 in. LCD HDTV
About a month ago, noticed an arched "shadow" extending from upper right corner of the screen to lower right center of screen - looks like a dirty swipe - shadow is only visible on lighter backgrounds - on close inspection, shadow appears to be behind outer screen - TV has never been bumped, etc. - outer screen is clean - TV is out of warranty (2 years old) - otherwise, TV performs perfectly - this is not a pixel problem - is this a heat issue, settings, or what?

A solid line down or across the screen is due to problems in the display itself. Unfortunately, there's no way to repair it because the bad circuitry is integrated into the display. The only cure is display replacement.
Not the solution you want, but that's how it is. (With the huge number of transistors that are part of the display, it's actually amazing there are as few failures as there are.)

Our Vizio started doing the same thing after only three weeks, except it was also showing green pixel when we watched DVDs. After checking this site and others and trying all the "tweaking" advised, I finally called Vizio's customer support. They were extremely polite and tried to help over the phone, but had to send someone to the house to make the repair (anything 40 inches or larger earns a house call). The tech arrived on time and was extremely professional and pleasant -- he had to replace the daughter board and LVDS cables. So far, so good.

It's likely not a backlight, but a mainboard. If you are feeling frisky, take the back off and get the model number off the mainboard and check eBay.

There is no backlight on plasma TVs. If you have a black screen than most likely one of your sustain boards are gone. Board can be purchased on line at about $100. If your TV has no signs of life it's most likely the power board. Any way it would not be that expensive to fix if you are able to take the TV apart and swap the boards. But I need to say that I recommend to do it ONLY if you are qualified enough. Otherwise ask your local TV repair company to service your TV.

a better solution is to replace the LVDS cables or just reseat them as the contractor stated it could be a motherboard but about 90% of the time it is actually the LVDS cables ohm load that puts toomuch load on the motherboard. the cheapest solution if out of warranty is buy an lvds cable and simply replace it if the issue still exist after the cable is replaced it will be a motherboard issue but any time you have red green or blue speckles on a vizio TV you should always swap the cable first since quite simply put it is the most common point of failure with that issue.
