Most of these older machine had speaker switches on the front panel. Can you check what they are set to. It may be that both switches(A and B) are set in, or set out. this could present the problem you are having with no sound. turn on just one switch that corresponds the connections you have made on the rear (use speaker A) Another thing to check, is when you first turn on the amp, do you hear a relay click shortly after you switch on. If you don't hear this delayed click, then there may well be a problem in the output stages of the amp. If this is the case, then you will need to take it to a tech to have a look and see what has failed in the amp. Hope this info helps, if you have any questions, I am happy to try and help you further.

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.
