Pioneer Elite Pro-99 Power Problem

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.

Re: Pioneer Elite Pro-99 Power Problem

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. good luck!

both may be a little hard to find anymore, the main problem is dead set and that is bad soldering all over the giant power supply board this set uses.

If you don't mind opening the thing, open it up and follow the power lead inside the TV. Somewhere along the line should be a fuse. I'd start there.

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.

Pioneer elite pro 100

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.

Pioneer Pro-118 won't turn on

Take off back cover. The problem power board is to the right of the board where the power plug feeds into the TV. There is a large white fuse right bend the power plug. With a meter it read ok; about 8 inches deeper into the TV on that board was the resister next to two fuses. My 4 amp 125 volt fuse did not read on my meter. After replacing, it worked fine. Check all three fuses while you're in there.
