Blown output drivers

Have you checked the power supply section? Also look out for any IC's in the amp stages. They can go causing that kind of fault.

In regards to getting a digital output off your CD player there really is not any point in doing this. With standard CD quality you are not going to get any audio benefit from upconverting to a digital format with the player.

You would have to purchase a $50 to $100 Analog to Digital converter and then you are still limited by the audio output of the Luxman d-90 cd player.

So I would recommend that you just use your analog outputs. If you are wanting digital output for your CD player you would be better off buying a new CD Player that has digital output.

Also note unless you are wantling to play digital CDs that are in a DTS for Dolby format there is no need for digital output on a CD player.

Let me know if you have any more problems or questions

Make sure that you have the turntable connected to the PHONO input. If there is none (I don't know your specific model), then you will need a phono pre-amp. Connect the output of the pre-amp to tape-in or Aux in and the unit should work as expected. The alternative is that you may have the tape monitor turned on. Check that as well.
This unit is old enough to have pre-out and amp-in connectors on the back. Make sure that those are connected to each other. Use standard RCA cables.

If none of those resolve the problem, there is an internal problem that will need a bench to resolve.

did the left channel work when u switched speakers, if so then the left speaker or wiring is a fault.if not then the output circuits on the amp are blown or the fuse is blown some amps have internal fuses in the output to protect the output transistors. unplug the power cord and take the cover off, look to see if u can find any fuses and check these for continuity u can hold these up to the light and u should see a fine filiment in one piece and not broken. these fuses sometimes blow just from age and use at high volume like a regular light bulb.If the fuse is blown replace with the same value else the output transistors will need to be replaced most likley along with the drivers.

The problem is still there, but I am expecting HELP fir free.

Hi....

Check on the speaker connections. Make sure theyre firm at both ends. Do you have another set of speakers you can try on it? If so,try that too.
The chatter is the speaker protection relay.

Let me know...Thanks

(1)When the unit is switched on the relay clicks in,but no sign of life, and then five seconds later the second relay clicks on/off don't know which. This symptom is DC outputted to speaker terminals. Check any DC at power amp stage output.(2)Must have blown up.
Positive. If Caps blew, your amp shutted itself down within 5 seconds due to + & - power supply creating an unbalanced +B & - B voltage not allowing your amp to turn on.

well it sounds like u may have blown the channel or your amp was powering your rear speakers

Hi: If the Amp has an audio output transformer, check for bad solder connections to the pc board, This are the wires from the transformer to the PC board. Another place to look is the earphone connection plug. If the jack has a bent contact inside of it, you will have all sound cut off. Good Luck.

If the outputs were blown, the 20 pin HIP4080 probably needs to be replaced.
