Blow out the dust through the top vent holes of the receiver as much as you can near the headphone jack area and then blow through the headphone jack hole as hard as you can. I had the same phonesin error and just blowing out the dust solved it for me. Dust I think can easily put enough resistance on the headphone jack circuit to make the receiver think the jack is in use.
I think I just fixed a unit with the same problem. I opened the cover and found where the wire from the headphone jack plugs into a board just beside the power supply transformer. When removed, the unit appeared to select speakers as the output. Since the headphones are never used by the owner, I simply left the headphone cable unplugged. Unfortunately, I didn't have speakers to test it with but the unit appeared to be working correctly.

I just tried this after trying all other possible solutions and this one was the ticket! Your the only one I've found that actually posted this solution anywhere. Thanks!

SOURCE: Pioneer VSX-505S Subwoofer Installation
That type of subwoofer is not used with this receiver. This receiver actually outputs no power for a subwoofer, therefore only needs a plain ol' rca signal wire. This is due to the fact that you need a powered sub... one that you plug in to the wall and it has its own built in amp. you simply run an rca from yyour 505s to that sub.

If you have just one pair of speakers hooked up and have both A & B speakers selected you won't get ANY sound out of unit, so check that?

Hi Tracey
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.

SOURCE: pioneer receiver vsx d814 amp error
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.
Good luck
