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.

Disconnect the speakers and see what happens. Carefully examine the speaker cables for unwanted connections (shorts).
Take a clue from when the power problem appeared. Something was moved and made the buzz a (probable) dead short.

SOURCE: Pioneer VSX 818V No Sound
First thing to check is the Speaker Select Switch. It will say, "A" "AB" or "Both" it will be displayed on the LCD screen as well. Second if that's ok, Check the "Direct" switch. If it's on, turn it off. Generally if it's on, you will see a blue light if it's on (most receiver's)
If you still have No audio, hook up your DVD to the "Direct" input and turn "Direct" on. If you have audio then. The DSP chip is probably bad and you should take it to a shop and have them bench it first to confirm. Hope this helps
