Question about Televison & Video
Giant black spot on tv from top to bottom in the middle only. it goes away on its own sometimes and i have no idea why. it will stay fine for a while then go back to having the giant spot again. help?
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.

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.

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.
