Question about Pioneer PureVision PDP-502 50 in. Plasma Television

2 Answers

Pixels exposing themselves across my screen. PDP-502MX

I have posted this problem before and didn't get any responses. So, I'm hoping someone out there takes the time to read this, and at least lets me know if the is a worth fixing problem, or a dumpster bound plasma. 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 pixels across the screen about 1/3rd down from the top. I can see them whether 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. Does any one know I this problem would be in the plasma display panel, or within the electronics?

    I have a Pioneer Elite PRO 920HD plasma which is three years old. It is mounted in a bookcase with 6" clearance above. For the past year after being on for various periods of time, darker pixels show up starting in the reds and then progressing. If I turn off the set for awhile to let it cool down the problem goes away and the picture is once again perfect. Have I not provide enough ventilation?

Try putting a fan on the back of the tv to see if it is getting better. If it does then you probally have a board that is overheating. If that is the case then CAREFULLY !!! remove the back and place where you can turn on and safely access the open back NO TOUCHING STUFF !!! Mabey lay it face down on a glass table or lay it on a table with 25% hanging over the edge to see the screen. Then take a COLD blow dryer and blow it on the boards to find out which one makes it get better. If one does then it will probally be your problem board. Make extremely sure that is the one before removing it by blowing from all angles on the boards around it without air hitting the suposed problem board. Then try a little hot air to see if that starts the problem on that board so you can be sure. Of course check the surrounding and offending board several times to be sure before removing.

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".

How do i delete craigslistaccount


Hello,The easiest way to cancel your Craigslist account is to let it expire - log in, delete all of your postings and drafts and then wait. You could change your email to a non-existent address, but that's not advisable, since someone could get into your account and start posting ads. Without the ability to get back into your account to delete them or get responses from the Craigslist help desk, deleting your hacked account becomes more difficult.
Here is website you can read to give you more info.

Hey


It depends really. The techs that answer questions here are doing it on a volunteer basis when we answer non premium questions. Really there is no way to say how long a question may take to get answered. Theres no guarantee it will be at all. I've seen questions get posted and answered within 5 minutes, it ranges by the time of day, who is on answering questions, or even how tough of a question you asked. If you really have an important issue that you really need answered then premium questions would greatly increase the likelyhood of you getting a response in a timely fashion. In addition to that, you may get numerous responses if you got the premium question route. Otherwise, I'd say ask your question and give it a day or two and check back.
