Question about Pioneer VSX-D511 Receiver
It actually blew up one of my speakers.I opened it up, tested a few components and they seem ok. I put everything back except the bolt hat bonds the speaker out put with the chasis. then the amps switches on and play for about 30 second and the popping sound again but no amp error. When I replace the screw tha binds the speaker output to the chasis ground the amp error appears immediately and the amp goes to standby. When I use my DMM to test if there's any shorting connection between the red and black and red and ground, everything looks clean. Any ideas? Lolo B

I've had the same problem for over a month and have yet to find the time to get to it. However, I there may be a fuse on the circuit board that needs to be replace. That's just my guess.
Hope it's the solution.

The Pioneer VSX-D814 has a couple of Power Hybrid bricks that do all the power amplification. These are the infamous PAC011A. You should have 2 of those in your receiver.
If the amp detects some unusual activities, it may shut down the unit to prevent damage. “Amp Err” usually means some DC in the output.
Disconnect all the speakers and turn on the unit; if it acts normal, reconnect speakers one set at a time very carefully. If the unit still shows the error message you can try to reset it. If the reset works, again carefully reconnect the speakers connections. If the reset does not recover the normal operation of the unit, you may have one of the PAC011A damaged, and the unit will need repair.
The reset can be done by disconnecting the unit power cord for a few minutes, then plug it in and press “FRONT ENTER key + ADVANCED SURROUND key” continuously for 2sec.

I must agree that if the fuses are open and you replace them that your problem maybe fixed. If you can remove the fuse, I recommend taking it to a RadioShack and see if someone there can figure out what it is. I am going to assume that the fuse should be a 250 V. If you can find one that matches the same appearance, go with the smallest aperage rating you can find. Go with this route only if the person can not tell you exactly what it is you need. Be sure to match the type of fuse if you can see inside it like in the case of a glass fuse. Some are slow-blow fuses and some are fast-blow. If you are uncertain your safest bet is to use a fast-blow with a real low amp rating for the voltage you are using. If the amp rating is too low, it may run fine at lower volumes and pop when you turn it up. If I could physically see the fuse, I would probably be able to tell you what it was and what you needed to replace it with.

Most probably you have one of the power amplifier modules bad. They are the PAC010 and PAC011 type. You can remove one and power up the receiver. If it powers-up normaly it's that one.... (50% chance) Otherwise remove both and it should power up normally. Beware that these parts are expensive... Most times just with a new part the problem is solved. YMMV. Good luck
