Question about Pioneer VSX-406 Receiver

1 Answer

Poweroff indication with no output

My Pioneer VSX-406 has been in storage for three years. We recently powered up the unit which appeared to be starting up normally, but then the indication on the front panel read "POWEROFF" and there is no output from the unit. We can still scan the radio bands, and there is electrical output from the 110 volt jack on the back of the receiver. There is no sound output, and each time we select a function we get the same "POWEROFF" indication. I've checked to see if there is a battery inside that might be depleted and found none. The fuse on the circuit board checks out okay. I have downloaded the schematic and repair manual, but found no solution in that information. What should I try next?

    Thanks Duncan. I agree that it may be a protector circuit function, but there is nothing in the user manual regarding this.

Have you tried the owners manual (not the repair manual)? It will probably have something about this. It may be that this is the generic message that the unit gives you when you have a bad output channel which would put it into a protection mode.

No sound from Pioneer VSX-37TX

1 Answer

No audio output


THE FIX - to audio problems that persist with the VSX-29TX and others using the AWX7272 DSP board is to replace the ROM on the DSP. My unit started failing on and off after 10 years of use! The intermittent DSP board is an Extremely Common and irritating Problem for this model! The replacement IC,(2) resistors + shipping and handling totaled $49.65 and my unit is finally fixed correctly! Don't believe other posts that you can get away with re-soldering; it will continue to fail again and again! Details of fix are:

Replacement for the old Pioneer ROM located at location IC 9374, should be done with the part PD6381A from Pioneer Electronics. You will also need to move (relocate) the 2 resistors (0 Ohm resistors) located at R9372 and R9371 to locations R9374 and R9373.

This component update applies to DSP boards marked as AWX7433, AWX7272.

This fix is validated (from Pioneer) on the VSX-26TX,VSX-27TX,& VSX-29TX it might also work in the VSX-908, VSX-908RDS and others as long as the same DSP board was used.

Let me caution and stress that surface mount soldering skills ARE REQUIRED to do this update! It also doesn't hurt to have excellent vision and/or an eye loop or microscope to check your work. Original ROM's were subject to timing changes internal to the part as a result of HEAT. This model does get HOT! The program was also modified as a further safeguard to re-occurrence.

VSX-D457 Display's power off and then shutdown


Most likely it needs one of the output ICs. But check for cold solder rings on the ground connections of the input board. Est. for it to be repaired $100-$120

I have receiver VSX-D509S. Have had it for


Check for a bad ground on the input circuit board. you will need to re-solder them. Remove top cover and rear panel (many screws on rear panel) The input board can easily be accessed and resoldered. you should also check for a bad ground on the speaker jacks. If it is not repaired, sooner or later you will probably need an output IC. good luck.
