I have a pioneer receiver vsx-5000 it barely has sound I turn the volume up and it still only has a little bit of sound what's the problem


The sound you are hearing is just the pre-amp that is working. It seems the main power amp has failed. A check inside and look at what is on the big heat sink might reveal the cause. If there is something that looks like the image that I posting below then you need to replace it. If separate devices then check the power supply to them or each one.

I've got a vsx-920-k Pioneer receiver with s-11 Pioneer speakers and a s-21w Pioneer subwoofer. All of a sudden my sub stopped working and it seems like it's stuck in standby mode (blue light...


The manual is here...

Flashing Blue is not defined in the manual.

Have you tried changing the Auto Standby switch to ON?

You can prove if the sub amp will respond to a known good input by TURNING ITS VOLUME DOWN tp start and just feeding it ANY RCA output from the receiver while playing, say, FM (to keep it simple). That way you would known in which direction the problem actually lies (internal or external).

I have a pioneer vsx d812 in standyby mode (red light flashing), i wanna how how i could fix it


Thjere are service manuals for it in this directory...

Generally speaking, an amp protects itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.


Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.


You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.


If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.


If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Cool Receiver! I have worked on many of them. Your regulator circuit will need a few zener diodes and possible some caps. It's amazing how good the capacitors are in these though, but the zener diodes fail all the time. I like replacing them all. Larry's Electronics ledstiles@hotmail.com

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.
