    Sorry for the delay. Typically, I would say, "With a DVM on the DIODE scale, and NO power applied to the receiver, check the Base-Emitter; Base-Collector; and Emitter-Collector junctions on ALL output Power Transistors. (They will all be bolted to a Heatsink). You are looking for anything less than approximately .450V (450mV). It would be best if you could send me the results, if you are unsure how to evaluate them". HOWEVER, this receiver uses (2) PAC014A & (1) PAC015A Output ICs, it would best if I send you a copy of the Service Manual. It contains all the diagrams and flow charts you need to troubleshoot this receiver.

I sounds like you may have a problem in either one of the Regulator circuits, or, one of the Power Amplifier outputs. If the protect circuit detects DC or Low Impedance on one or more of the speaker lines, it will not fire up the high power section of the power supply. Further troubleshooting will require some working knowledge of power amp and power supply circuits. I've got a .pdf copy of the Service Manual if that will help you.
Please let me know what your level of troubleshooting ability is, and whether the manual will help you.

SOURCE: Pioneer VSX-D411 receiver "Amp Error" message

Hello,
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.
Good luck

Hello - Our Pioneer vsx-305 display screen doesn't light up anymore and we are unable to get it to work even though the on/off button appears to operating correctly (red standby light comes on). T


It is likely failing due to age.Cold solders fail, corrosion can cut a connection, a capacitor can harden and fail... a myriad of things can happen in time. Repairing it will cost more than an inexpensive replacement. The same receiver can be had on ebay from $60 up (with shipping). It is a cost benefit issue at this point.

"enter and advanced surround keys"? I don't see that documented as a special function in the manual.

BTW: other than the Flashing light, is there a malfunction?

Page 72 describes how it REALLY resets...

Resetting the main unit

Use this procedure to reset all the receiver's settings to the factory default. Use the front

panel controls to do this.


1 Switch the receiver into standby.


2 While holding down the TONE button, press and hold the STANDBY/ON button for about three seconds.


3 When you see RESET? appear in the display, press ENTER .

OK? shows in the display.


4 Press SYSTEM SETUP to confirm.

OK appears in the display to indicate that the receiver has been reset to the factory default
settings.

the light is an ledt they very rarely go bad ..to confirm its bad you must first see that the led is getting power --a voltmeter one end to the frame of the unit and the other to either lead on the led will confirm if its bad or not a typical led will run on or near 3 volts dc... if theres no power at the led than the problem is elsewhere

My Pioneer VSX-D704S WILL NOT POWER ON. WHEN I PUSH THE POWER BUTTON NOTHING HAPPENS. THEN THE STANDBY LIGHT COMES ON.


It is in protection and will need to be serviced. Find a local AUTHORIZED pioneer service center.

Blinking Standby


regarding the Pioneer VSX-912 blinking standby light. This is how you reset it; press the "advanced surround" and the " enter" at the same time for about 3 seconds. Make sure you press the ENTER on the reciever (its the one on top next to the small dial) If you press the "ON" instead of "ENTER" it will not work. If an error message comes on and shuts the unit down, just reset it again. This should save you some $$$$. To bad Pioneer did't put this info in the manual.
