Hello,
Most probably you have one of the power amplifier modules bad. They are the PAC010 and PAC011 type. You can remove one and power up the receiver. If it powers-up normaly it's that one.... (50% chance) Otherwise remove both and it should power up normally. Beware that these parts are expensive... Most times just with a new part the problem is solved. YMMV. Good luck

My amplifier when i put it at -50 and more it write overload .....pionner vsx-d511


Generally speaking, an amp attempts to protect 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.

Check for loose speaker connections at the speaker as a root cause for intermittent shutdown.

Pioneer VSX-D511 Comes up with AMP ERROR and shuts down


I must agree that if the fuses are open and you replace them that your problem maybe fixed. If you can remove the fuse, I recommend taking it to a RadioShack and see if someone there can figure out what it is. I am going to assume that the fuse should be a 250 V. If you can find one that matches the same appearance, go with the smallest aperage rating you can find. Go with this route only if the person can not tell you exactly what it is you need. Be sure to match the type of fuse if you can see inside it like in the case of a glass fuse. Some are slow-blow fuses and some are fast-blow. If you are uncertain your safest bet is to use a fast-blow with a real low amp rating for the voltage you are using. If the amp rating is too low, it may run fine at lower volumes and pop when you turn it up. If I could physically see the fuse, I would probably be able to tell you what it was and what you needed to replace it with.

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.

I have the same problem. It worked before and now the sound is gone. If I put it on tuner and turn it up all the way I can hear a little bit

Internal cooling fan not spinning


There should be a thermistor mounted on the heatsink which will trigger the fan. The fan will not likely turn on if you are using your receiver for 2-channel music. Try using all amp channels by playing a DVD in DTS or AC-3 audio mode and crank up the volume - lots of bass will do the job. You can place a piece of tissue paper near the vent so you don't have to use a flashlight to watch and wait until it turns on. My receiver takes about 3 songs from the Eagles DTS DVD at high levels before the fan would turn on. As soon as the temperature is lower than the limit, the fan would turn off.

Clark, you MIGHT have a simple problem here. Let's keep our fingers crossed... This problem generally has more to do with the speaker WIRES or their IMPEDENCE than anything else, even though the receiver displays "AMP ERR." (Technically, it IS an amp error, but the source MAY not be the amp!) The very FIRST thing we need to do is check to make certain ALL of your speakers have an IMPEDENCE of 8 OHMS. (Pioneer says 6, but that's not necessarily a good recommendation, particularly if you listen LOUD.) Virtually all speakers of even modest quality will include this specification on a label on the back of the speaker. You CANNOT run more than (2) TWO speakers with 4 OHMs impedence on ANY amplifier (technical discussion too long!) [NOTE: Your receiver has internal overload protection systems to prevent permanent damage. On SOME Pioneer models, these can be "reset" but you can't do it yourself. Your dealer or authorized service center must do so.] But, before you take it in for service, there is one more "test": check for shorted and/or mis-connected/disconnected speaker cables/wires. 1) Visually inspect connections at the receiver AND speakers. You might find something obvious! Look for bare wires touching one another. Again, you must look both at the receiver, AND at the speakers. 2) If everything looks okay, then disconnect ALL of the speakers at the receiver; and reconnect and test them one at a time (at relatively low volume.) For example, reconnect the left front speaker, test the system; THEN add the right front, test the system, and so on, ADDING one more speaker each time - FIRST MAKING SURE EACH OF THEM HAS AN IMPEDENCE OF AT LEAST 8 OHMS! IF there is a short (or bad speaker) this will help isolate it. Hopefully one of these simple fixes will get you up-and-running. Good luck!
