With the receiver off, press ENTER + ADVANCED SURROUND keys continuously for 2 sec. and it will tell you the fault it encountered. Even if it has a short, it will still protect the speakers; however, it is still a good idea to disconnect all speakers before doing this.

I have a pioneer vsx d503s and the standby light is on. But the receiver will not come on


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.

Optical inputs


You have to re route the sound from the samsung to the optical output. You do this is the audio setup section of the setup menu.

My component pioneer vsx-518 has no power, what is the main reason and which item will i check?


• If you have a multimeter, check for DC outputs on the power

supply regulators, there could be some


• Or check for cold solder joints (if you can't find any)

diodes, capacitors or regulators

on the power supply.

• These could be just a power supply problem, main amp or both


Let me know if you need further assistance!

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.

I have a motorolla DSR505 sattelite receiver that I want to connect to my Pioneer VSX-1019AH-K audio/video receiver. The sattelite receiver has a DVI output jack so I have a DVI to HDMI cable to connect it...


The DVI output usually transmits only video (I'm almost 90% sure about this). It would be better if you did not use the DVI to HDMI cable. Receivers and displays can be very picky when it comes to using HDMI. Your Motorola DSR505 has other output options on its rear. I would suggest using the Component out for video (the 3 outputs colored green, blue and red) and either an optical or coaxial for the audio. The Pioneer VSX 1019 AH-K has the required inputs. Of course, you would require new component and coaxial/optical cables to do the job.
Hope this helps. If you're still in a tangle, you can consult the Official Thread on the Pioneer VSX 1019 AH-K on avsforum. There are a lot of helpful people out there.

Sibilant output from Pioneer VSX 1018 AH-S


Suspect a DTS board capacitor failures the ESR characteristics.

To troubleshoot connected any available device to RCA stereo connections at input to multi channel in. Test input to the corresponding speaker output confirming audio quality. This circuit bi-passes the DTS function and connects to the power amplifier for the speaker.

Connect any audio amplifier from the preamp out and confirm the quality of the audio.

I suspect that the pre-amp out will contain the distortedf noise. If the distrotion appears in all the channels it is most likely the DTS.

These are repairable.

Hope this helps?
