Your tv has multiple backlights in it... sounds like one of your inverters are going. Don't be surprised when the tv stops displaying anything at all.

SOURCE: Blue/black vertical line in the middle of screen

Sounds like a bad connection on a ribbon cable or plug comming or going to the LCD display. This is something you should not try to fix as these circuits are very very fradgile and you can easily break or tear a ribbon cable . Call the manufacturer to get a tech to assit you. Good Luck

SOURCE: Vizio P4 Plasma green blotches

OK Service tech came out last night (7pm) and repalces the main board and updated firmware to the latest. he said the red/green snow is a fairly common problem with the early units (mine was a july 2006 build). Picture is fine now but we will see how long the fix lasts. Main board was definitely the issue, firmware upgrade was prob just because they could.
Keep in mind this unit was OUT of warranty. I find it refreshing that Vizio took responsibility and set up a service ticket for a 16 month old unit. Not that they shouldn't last a lot longer but they could have just said tough luck.

SOURCE: Green spots/pixels at top of TV screen

I have a 50" Pioneer PDP-503MXE with the same problem - the fans don't run. It appears to be a problem with the temperature sensor that controls the fan speed. However, the fans can manually be switched to MAX.
To do this, put the display in standby. Press the 'Menu' button and within 3 seconds press the 'Power/Standby' button. The 'Integration Menu' will appear. Select the 'Option' tab on the right. Scroll down (next page) to the 'Fan Control' option. It will most likely be set to 'Auto'. Press 'Set' to change it to 'Max'. Within a few seconds the fans will run.
At Max the fans are a bit noisey but it will cool the unit down.

Having a big yellow spot background in the middle of the picture.


Hi , it seems you are experimenting a light engine problem.Here's how your tv works: http://www.youtube.com/watch?v=ZLLHnQ4y-wo Basically there's 3 LCD chips that create the colors and image by blending together.When these chips start to melt you will get those blue spots, pixilation even vertical lines.You will need to replace the light engine. Have a blessed one!

Black spot on screen


Your son turned on the closed captioning text mode. The black box is where it would appear if there were any text. Go into your setup menu and turn off the captioning, or restore the factory presets.

Sony 60" LCD projection TV has yellow screen discoloration


It sounds like you have a bad Blue Polarizer in the light path. I'm sorry but that is something you will have to contact a service center for. It's not something you'll be able to do yourself, I'm sorry, but that's the best advice I can give you.

Red spots


what you can do is take off the back pannel and there is a cord on the top of the board that looks like a computer board, there are many boards in the TV but the one I am talking about is twords the bottom where the video jacks plug in to the TV. Ok once you have located the pannel there is a cord on the top kinda tword the right side, it is many wires inside a black covering. What you need to do is just simply unplug it and plug it back in, do this as many times to try to get it to work. If that doesn;t work you can replace the cord and if that doesn't work then the screen is out and would cost WAY too much to fix, you could buy you a new name brand TV.

Top screen has black spot


A black spot means the top LCD screen is cracked / broken unfortunatelly for you.

If you are technically inclined you can buy a replacement in any online store and replace it by yourself but its a bit complicated as you practically need to carefully dissasemble all the unit to do that and would need at least some skils, a special thomson 3 windings small screwdriver (sometimes the same store sells it) and small blade and philips screewdrivers. You can find a video and instructions to do that over the web and decide if too difficult for you.

Good Luck...

Sounds like a possible bad pixel. I would power the machine down, reseat the graphics card, reconnect the dvi link, and reset the PRAM.



Keep me posted.
