Hi,
I bought this receiver a few years ago. It's been seating in a corner for some time since the unit keeps shutting down when cranking up volume. It happens before -5dB. I tried swapping wires of speakers and turning on unit with one speaker at a time, but problem happens even without any speaker in, so it's an issue with the receiver itself, not the speakers or speaker wires. I vacuumed the inside and checked the only fuse I could find. I looked online for help but couldn't find anything else than what I already tried. I found the service manual online but I am not electronically savvy so I could use some help. I'm already at a loss with this unit so I'd rather fix it myself than have a pro look at it... Also, I noticed that the two biggest blue capacitors inside are bulgy on top, but not leaky. Not sure if the bulging is normal or if it's a sign that they're bad. Not sure how to test those; do I have to remove them in order to test them? Thanks for any input you may have!
That is a very old prologic receiver with DVD player.
I can tell you it is not the caps. Something is taking too much current. You are not going to fix it because you have no experience. You need a FET VOM, O-Scope, and signal generator at a minimum. You also need a Variac to work on it safely as you have to work on gear live.
I doubt you can get parts and the local service guy is long gone.
That unit is junk and needs a one way trip to the recycling center.
If you really must have one of those, then you can get them for $50 to $100 on eBay. You won't get into the door of any service center for that much.
By the way, I note from reviews at the time, they were a problem unit from the beginning. Remember fixed junk is still junk. Get rid of it.
