My Pro-99 will not power on. If the unit is off completely, pressing the manual Power On button will cause the unit to momentarily power on, the green light comes on and then the unit immediately powers off and the red light comes on. Pressing standby then does nothing. Turning the unit off manually (or unplugging it) will allow the above sequence to be repeated. Nothing I have been able to do enables the system to stay powered up.
If you're NOT still under warranty you should at least open the TV and look for a blown fuse near where the power cable enters the set. A lot of times you can buy replacement fuses at a local electronic or hardware store and they're easy to replace.
Check the fuse. If it is blown, it will be obvious and make sure that the set is unplugged before replacing it. If it blows again, or if it is not blown, your problem is probably in the 'X' volt regulator and you will need professional help with the repairs.
You can also check the board where the components are mounted and resoled any that look bad. Brief power outages may cause the TV to turn off on its own. If you are using a surge protector, try connecting the set directly to the wall outlet.
In your case it could caused by a blown fuse, a leaky diodes or a bad solder joint at the horizontal drive transformer.
All can be replaced at a local electronic or hardware store and they're easy to replace
If this does not correct the problem, you may need to have your TV serviced.

Unit is pretty old I had one of these back in 98-99.
Time to upgrade a service tech is going to cost you $150 just to open it up and figure out whats bad.
Pioneer ok but check out Denon's line of receivers Onkyo is good too but they have a high rate of repairs
Pioneer doesn't make them like they used to that D1S was a tank, had tons of audio / video inputs was one of the first with video upconverting had lots of power and a great front display panel. BUT technology has come along way and pioneer hasn't kept up. They even stopped making high end TV's a few years ago even though they were regarded as the best sets out there.
check this out Denon AVR-4310CIgoogle it they sell for ALOT less than sticker I bought one for $1299 with a 5 year warranty
Sorry I know your model number and its a Power Down trouble with the Scan IC's that are in the unit. You need a tech to look at it and he will most likely find a bad Scan IC and it will need to be replaced. This a is a relatively easy fix for him.
your tv's hardware might got the problem. this should fix with an expert technician that they have a tools for fixing this problem. if repairing will cost you alot then i suggest that you have to buy a new tv insted of repairing your old tv. hope that helps!
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.
My set is doing the same thing again. The last time I fixed this (4 years ago) it was a capacitor gone bad in the power supply for the 24v standby circuit. (C166)
The service manuals can be ordered directly from Pioneer Part Number ARP3014 for Pro-100 model.
