In my experience, NG on a system made in Japan means "No Good" (error). NG might stand for something else, but regardless, it sounds like an internal issue with the amp.

This indicates the audio output stage in the receiver is loading down and triggering the overload protection circuit to kick in. Check the speaker wires for shorts, if okay! you will need a professional to assess the cost for repair.

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

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'll ask again... What brand/model of monitor?

Does it seem like a receiver-to-monitor On Screen Display message or is it something the monitor is warning about?

How are the the receiver and monitor connected?

No more sound from where? The TV. The speakers running off the receiver?

What source(s)?

Give us some clues, please.

First thing to check is the Speaker Select Switch. It will say, "A" "AB" or "Both" it will be displayed on the LCD screen as well. Second if that's ok, Check the "Direct" switch. If it's on, turn it off. Generally if it's on, you will see a blue light if it's on (most receiver's)

If you still have No audio, hook up your DVD to the "Direct" input and turn "Direct" on. If you have audio then. The DSP chip is probably bad and you should take it to a shop and have them bench it first to confirm. Hope this helps

All you have to do is connect the coaxial out from pc to any audio i/p at the back of vsx d512.but ensure you select the right channel to play the audio ( eg. tape i/p select tape at front control, aux i/p select the aux at front control )
