RGB Pixels I will play a game off of a disc for about 5-10 minutes when the screen will suddenly be flooded with red, blue, or green pixels. While I can still see the image on the screen a sheet of pixels is over it. Sometimes the pixels will go away and come back in a different color. Other times the groups of off colored pixels begin to change position. What is wrong with my 360?

The Video Controller works off of the RGB principal. RED/Green/Blue pixels. The mix color is dependent on the formation and density of the pixel and rates. When one or more colors are absent the only functioning color will dominate, and it is Green in your case. The screen liquid crystals in Red and Blue are failing and only a screen replacement will fix the situation.

Purple Panasonic PC>TV Problem:
The VGA cable uses three primary color RGB channels.
Red, Green, and Blue.
The picture is made up of pixels or dots arranged in a grid along the "X" horizontal axis and "Y" vertical axis.
The computer mixes the intensity of each color channel to create a unique color per pixel.
All RGB at 100% creates white.
R+G creates yellow.
R+B creates magenta, ie purplish.
G+B creates cyan.
So a purplish tint sounds as if your Green wire has no signal, which may indicate a faulty VGA cable or VGA socket.
Put another way, (R+G+B)-G=R+B=magenta.
So try another VGA cable, spray all socket pins with "Servisol " or similar contact cleaner.
0%<--------->100%
Cyan<------->Red
Magenta<--->Green
Yellow<------>Blue
All 0%=Black; All 50%=Grey; All 100%=White.

I assume this is related to your LCD monitor.
I think you mean dead pixels. The LCD monitor has tiny pixel elements, one for each red, blue, green color and each one of these colored pixels are turnes on by a transistor. When a transistor fails then the colored pixel it controls does not light up. This is a dead pixel and it shows up as a tiny black dot.
If the screen displays a blue screen, a dead blue pixel will appear as a tiny black dot in the blue screen.
You normally would not notice a few dead pixels unless they are grouped together.

try another HDMI cable also clean your Blue Ray laser

its your junkbox getting ready to redring. Thanks Bill. unfortunately ive had the pleasure of watching 3 do this. One today. .

LCD screens occasionally have what are called "Stuck pixels". There is a tutorial in wikihow which might help you out here:

Try that and see if it helps. Stuck pixels are actually a slighty common problem.

Its processors problem that gives pixels missing result in certain modes. You need to replace Video Processing Board and it will be available from Samsung service.

Those small pixels are now damaged not much u can do with it. Some people say you can press on the screen the pixels affected and possiblilty get them to make contact and light back up ( I honestly highly doubt it) If u can live with and not very distracting keep watching it. But if you want to order a replacement, more than likely it will cost more than the TV did when u bought it. If its still under warranty get it replaced if possible.

This is because the RGB filters in the camera are not perfect, and there is no one "green" colour. The green pixels pick up a wide band of colours, and are somewhat sensitive even to red and blue, especially near where green shades into red.
