Pioneer PDP-5071PU TV turns itself off an freezes

Ever since I have owned my Pioneer PDP TV it has turned itself off then the on/off swith flashes blue.
It also freezes up where the channel display on the TV will not autohide. If I turn the TV off and back on the TV displays ''warming up'' but it does not aways come on for a long time.
I have had it in the shop several times (Pioneer paid) but they never get the problem fixed. Anyone else had this problem and found a solution.
I think it overheats by the symptoms.
Thanks
Mike

SOURCE: Hi everyone! I have a pioneer

The Y Lower buffer is the most likely culprit. I would first try to firmly tap on the TV... about 3" below the center line on the right side front (not on the screen but right next to the screen). The Y Lower connector is there and it could be just loose. I have a Philips 50" plasma that the lower half went out and a gentle tap fixed it once. I took it apart and tightened the connectors by loosening the screws and pushing the Y Lower buffer toward the Y Main board while tightening the screws back. No problem with it since. But sometimes the buffers go bad on these units and need to be replaced. Some people replace the upper and lower at the same time while others say just replace the bad one.

Good luck and let me know what you find!

SOURCE: My pioneer pdp-5080hd plasma tv is turning off on its own for no reason. Both blue and red lights just turn off. No flashing. It comes back on afte a few minutes and there is a gray box that says

If not happening on a predictable basis it will be hard to find--some general information:

I see so many here with no sound/nopicture issues:

ISSUES:

1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.If set is opened at least look for puffed up and bad caps like in thisphoto.

How do i connect head phones to pioneer pdp 5071pu TV


This model has no headphone out put. In the rear panel there are two monitor audio outputs which could drive headphones, but I think the volume output to a possible monitor matches the tv loudspeaker output, and may not turn off the audio separately.
