Question about Pioneer PureVision PDP-503CMX 50 in. HD-Ready Plasma Television

4 Answers

Pink pixels across plasma screen.

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.

    I have this exact problem. Mine has been doing this for about three years. It seems that the problem arises (gets warmed up) when a bright solid color is on the screen for a while. The monitor used to have a high-pitched whine as well when there was a lot of white on the screen, but that seems to have gone away.

    Nothing I have tried adjustment-wise has helped.

    Have you had any success dealing with this issue?

    I have the same problem. Once the screen warms up pink pixels across the top of the screen. This has been going on for about 1 year and seems to be getting worse. Anyone have any ideas?

    Everything I have fund out through researching this is that the problem is due to not enough pressure in the plasma.... My problem started during a hurricane. Supposedly, the only fix for this is a new panel. Might as well buy a new TV, it's cheaper. I just bought a 65" Panasonic.... Very nice.

    I have the same problem. My unit is 7 years old and I just spent $100 for zero help since the problem was not observed in the service center. The problem has been increasingly noticeable for about 3 years.

    It takes about an hour for it to appear and then it slowly increases across the top 1/3 of the screen. This looks to be a heat related problem since it was running a DVD at the service center for over 2 hours and the problem did not show up. The center is kept fairly cool so this may be why the problem was not observed. I went to the center to verify that the problem was not observed after they told me the unit had been running for about 2 hours.

    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 build up.

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.

How do I correct pink and green bands accross HP-R4252 Plasma TV

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.

A reddish cloudy swirl sweeps across part of my screen.

IF you are seeing a red or pink large oval area in the middle of the screen, I can tell you what the problem is.

It is not the lamp.

Let me know if you need more information--please confirm you have the red or pink oval.

Screen goes pink and green starting with a few pixels

Best thing to do, try a different known working monitor to hook up to the computer. If the screen works and doesn't change colors then you know its the original monitor that is bad.

If you hook up the known working monitor and the same problem happens then you know its the video card that is bad and the video card would have to be replaced.

40" Sony BRAVIA KDL-40S2010 LCD HD TV

what kind of cables are you using? Make sure you get the HDMI cables. Also, the S and V Sony series only have a refresh rate of 60Hz, which means that when you get fast action scenes or when people are moving, you will see a very noticeable blur. There really is nothing you can do about this. I had a V series and immediately returned for a W series, which has a refresh rate of 120 Hz. Sometimes, you can still see the pixelation, especially if the TV can't handle the response time, but it is definitely less noticeable than the other series.

Pixels exposing themselves across my screen. PDP-502MX

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".

Faint Horizontal Line

Your problem could be a bad LCD screen, and beleive me will get worse with age. It could be a Driver IC is not putting out the proper drive for that matrix of TFT. If you have a warranty, stand by your guns as its not right, so call and have the servicer make it right. Good Luck PS please do not forget to rate this thread.
