I have a pioneer received that shows amp error after being on for a while


Contact any service technician. There is some fault [internal circuit board/s]. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/

Amp error pioneer


Hi pat,

For pioneer Amp error:

It means that microprocessor has detected an abnormal DC voltage:

Speaker relay will be Off, then flash "AMP_ERR" on display.

If the AC plug is pulled off within 60 sec,

and then it is plugged in again, the unit will be reset for 60 sec.

When I turn on the unit it only stays on for 2 seconds then shuts off. I have unpluged it and pluged it back in. I checked speaker conections. There have been no electrial storms or surges that I know...


Since you have done the required test but the amp tends to go off into the standby position then it becomes important to check if this is the PROTECT MODE.
In most cases of the amp cut off soon after the ERROR amp detects there is a higher CURRENT drain than required in the design. So the error amp cuts off the relay / or does not switch over the relay so as to safeguard against higher current , possible burn outs.
In this case you need some technical help to check the outputs, You will need to check for shorts on the outputs, disconnect each of the channels, disconnect power to either channels till the error amp resets.
Finally with the amplifier removed off the power for some time, press on all the front panel buttons to ward off the residual voltage, then while the power is plugged on , keep the input selector/standby power pressed On, just in case to reset the processor if an error had crept in.
Also check if any speakers have shorted.

Pioneer vsx-d511 amp error


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.

Stand by button flashes but receiver wont turn on


I have vsx-d812 that has an AMP ERR in error menu. the troubleshooting was found to be Q696 and Q697 in the DC prot. area on "C" board, up near front toward diplay in center of c board. You can get access to error codes on VSX pioneer unit by pressing "enter" and "adv. surr." simultaneously for 2 sec. The display should show what error code you are experiencing. I believe there are three diff. error codes. 1) AMP ERR 2) OVERLOAD 3) BOAD ERR (not mistyped) I hope this helps pinpoint error code for ya.

Amp error


I had this exact same problem, it can indicate that there is an impedance mis-match somewhere. i.e. using 4 or 6 ohm speakers instead of 8. However if you unplug the speakers and it is still doing it then you could have a problem with the actual amp circuit.

Mine was doing it with nothing plugged in and had dry solder joints on the circuit board with the two large output devices are. Simply resoldered those and it is fine now.

It had started crackling before it stopped working all together, which would also indicate the start of dry joints or bad connections somewhere.

Regards,

Rolf.
