20 Most Recent Pioneer VSX-D412 Receiver Questions & Answers

take it in for an appraisal but it would be a good excuse to update and not feel guilty

Hi I have same issue and I also get feedback from one speaker and hissing from time to time. smarthome2 will you be able to assist? Thank you.

I also have the VSX D412 and DirectTV. My DirectTV remote controls the D412 fine, but I did have the same problem you're experiecing with a Sylvania flat screen that the remote wouldn't operate. I corrected my problem by turning the TV off, then back on using the TV's remote, then telling the DirectTV system that I didn't know the model number and let the system search for the code. Hope this helps.

It doesn't support direct connection of a microphone.

You could have a blown channel. This will keep your receiver from turning on. It is a protect feature to keep you from damaging more components

The audio procsesor could have some garbage in it and if you leave the unit unpluged for from the wall for 40 Min., that should fix the problem.

In case you didn't see this on the other post, it is not the function of unpaid Fixya Experts to do the web searches for or read the manuals to those who can do it themselves. Most questions submitted to us would find answers immediately if they were typed directly into a search engine.

If you don't have the manual I recommend you get it. There may be other questions. A search for "Pioneer VSX-D412 manual" finds it.

What sources fail. How is it with test tones? have you isolated (swapped) the speakers?

Here is the service manual if you should ever need it. http://www.kallhovde.com/pioneer/tricomp/Audio/VSX/VSX-D412_RRV2727.pdf

Speakers A and B are intended to be pairs on each, not one on each. Look in the manual.

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 possible root cause for intermittent shutdown.

The unnamed TV's manual would give some guidance about ITs end. As would this one...
