I have recently started seeing pink pixels across the screen, sometimes more noticable than others. There are times when I have a beautiful HD picture with out a trace of a problem, then the scene will switch, and I can see thousands of them across the screen about 1/3rd down from the top. I can see them whether if it's HD I'm watching or standard. Sometimes they are barely noticable, sometimes I can even see what I'm watching. Dark scene, bright scene, doesn't make a difference.

Re: Pink pixels across plasma screen.
Usually it has to do with overheating. I started seeing a small amount on mine after watching a DVD and then a blu-ray for about an hour. It was a small amount but on the right side of the screen toward the top. Not sure what the solution is though. Most of the heat on mine is right at the top of the screen.
Had the same problem. Called the TV repair person and they turned up the voltage on the green pixels and it fixed it right away. Took about 20 min to do. Luck I bought extended coverage for an in home visit. But he said it's a common problem on plasma screens and most TV repair people are familiar with it and can do the repairs. Just make sure the person you take it to is an authorized repair person for your brand.
Do others with this problem have their small top corner fans working
correctly? Is there a way to set these to run continuously since this
may be related to a heat related problem with the display due to heat

First of all try, changing the input device to some other and see whether you see the same problem. Then connect your present input to a different TV and see. If you feel the input is ok, and it is a problem in the display, this is a case to be handled by a qualified service technician.
Have you tried lifting the ground on the TV? That set has a grounded (3-prong) plug and sometimes sccrolling lines can be caused by a ground loop in your power lines.Are the green and purple lines very short, like just a few rows of pixels tall, or multiple inches, like 3 - 8 tall?
Sounds like your panel might be going out or a faulty video card. This is the first time I have heard of a solid pink screen on a plasma. Usually this happens on LCDs, though they sometimes go white and stay white, which does signal a bad panel. tv needs repair
Onece the plasma heats up it shrinks a little, i think the cause is that you are low on plasma, so when i heats it shrinks and since the plasma cycles, the area low on plasma wil move slowly around the screen, take this to a repairman and more plasma can be added to it.
If these pixels are always in the same place, then I would suspect the plasma display panel. Pioneer is best known for their "Elite" series HDTV which have great picture quality, but for my money the rest can go to the dumpster. If the pixels change to different areas of the screen, then you probably have induced electrical noise in either the wiring or the circuits. Could be faulty engineering or workmanship. In that case, it could be worth getting it looked at. You may need to display a "static" picture, either from freezing a DVD scene, or getting a calibration DVD to see if these pixels are always visible. If the pixels only become visible after being on awhile, it could be the heat build-up causing a solder connection or semiconductor to act up (this model does use 470 watts of electricity when on, and you know that puts out a lot of heat to help breakdown components). Sorry I can't give you a magic cure, I absolutely refuse to work on pioneer TV's so I'm "out of the loop".
