Do you have any idea what could be wrong?
I watch for about an hour then it pops and cuts off.
I hear a clicking sound. After the clicking sound I can turn the set back on and maybe watch for another 1/2 hour then the same thing all over.

Re: Pioneer Elite PRO-520HD POPS the SHUTS OFF
It could be a couple of things doing it. The lead on the CRT , The Flyback and or splitter are just a few of the things that come to mind. be careful as thats high vorage and a arching CRT or Flyback lead can be very dangerous . It is usually best to callm in a professional for those kind of repairs and diagnosis unless your a skilled technician , let a repair shop handle the problem and be safe.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.

The model indicated here is rear projection that uses three picture tubes.
If rear cover is removed--can be done by removing entire front screen but there are hazards like damaging the screen---with rear cover removed clean the lens in the three round cyclinders which point up and are hard to miss===
They are the light source for the picture---there is if you look up inside and to the rear a mirror but unless grimy it rarely needs cleaning.
clean the lens with a lens cloth or even a paper towel with glass cleaner sprayed on the towel.
These intermittent failures are hard to find. The "pop" noise you're earing might be cause by a coolant moisture near the high voltage connection, sometimes the coolant might leak onto the CRT causing the high voltage to arc creating a conductive pattern for the high voltage to discharge and that will also cause the TV to shutdown.
Let me know if you require further assistance.
We are having the same problem of the Pioneer Elite Pro-99 turning itself off all of a sudden. The red 'non' power button comes on as if we had turned it off remotely. We would love to resolve this. If you can help let us know.
It is most likely just solder connections on your power supply. If the only diag LED that lights is on the supply, then thats usually the case. You can unplug the set and remove the supply to fix it with a little soldering. You have to remove the metal board supporter from the bottom of the board and solder quite a few connections. Look for cracked connections on the power connectors to the rest of the set, and also connections on the main transformer. If you need soldering experience, get a kit at radio shack and build a little project to get some practice.
FUNNY.... cause I just started having this problem also... I have had this TV since they first came out. LOVED it.. now I HATE it. I can watch for about an hour then POP the TV shorts.
wait a couple of minutes and you can get maybe another hour until POP again!
