Pioneer VSX-D411 receiver "Amp Error" message

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 'nekkid'. 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 another possible root cause for intermittent shutdown.

hi
guess you blow the transistors. can be fixed by service dont panic.

I believe it's trying to tell you something is wrong with its digital sound processing.

This was the best source I could find on it:

If you switch it to satereo / direct and the light goes out I'd say that would clinch it.

I have a Pioneer VSX-D411 and there is dsp ng flashing

Circuit problems -- take to pro/tech for check put

Lo mas probable es que hallas recalentado los ICs amplificadores de audio y vas a tener que remplazarlos.

Yes techtod you are right you do have to tell the receiver what you want it to do usually on the front panel you can access set up menu and go into input set up This is an example Say you plugged the dvd into optical one or coax 1 you must go to the input that says dvd click down till you highlight dig input and then select optical 1 or coax 1 there can be as many as 8 digital inputs so just check wich one you plugged it into and then tell the amp then you should be back to watching your digital movies

Here's a link to the owners manual:

try turning the unit off in standby mode then hold down the enter button and then the power button for about 10m seconds that should reset the unit depending on how new the unit is it sometimes has a digital saftey setting but i doubt that would cause it to do what you are saying

I had this exact same problem, it can indicate that there is an impedance mis-match somewhere. i.e. using 4 or 6 ohm speakers instead of 8. However if you unplug the speakers and it is still doing it then you could have a problem with the actual amp circuit.

Mine was doing it with nothing plugged in and had dry solder joints on the circuit board with the two large output devices are. Simply resoldered those and it is fine now.

It had started crackling before it stopped working all together, which would also indicate the start of dry joints or bad connections somewhere.
