Question about Pioneer Audio & Video Receivers
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.

Fastest way to test is to disconnect all speakers and turn up the vol. If it clips it needs service, then re-connect 8ohm speakers one by one and test until you find the speaker or channel that shorts. Then take that same speaker and hook it up to another channel and test, if it shorts, you know now it is either the speaker or the wire. Now, use a new piece of speaker wire from the same channel that caused it to short, replace the old and test. If it shorts, you've got a problem with the speaker. If your handy with a multimeter, check the resistance at the speaker and you will have your answer. If you are not familliar with a multimeter, just hook up a different speaker where the bad one is and test. It's just process of elimination. Hope this helps

Unfortunatelly your receiver has failed. The front panel is telling you one of the power modules is probably bad. Not an DIY type of repair. These parts are near $40.00, plus cost of replacing.
Look at options to replace your trusted receiver with a new one.
