My nad 1700 tuner hooked up to a nad 2400 power envelope works at times for radio, no music. The cd player works all the time. So that means it's not the power envelope amplifier ? It's the tuner ? Do I have my monster cables hooked up from the amp to the tuner in the wrong manner ?

if the receiver turns on and operates then eventually turns off due to protection mode its because a wire is shorting out the receiver.if it doesn't turn on or goes straight into protection mode then its probably time for repairs or a new receiver.

Maybe an FM amplified indoor antenna could help you to get a stable FM signal.

Sounds like your control pots are dirty. Remove the knobs. Get some good cleaner at Radio Shack. Something with alcohol, and some other ingredients which will remain. Try tuner cleaner, blue shower, etc. Spray the cleaner into the pots and rotate end to end. May have to do this several times to get all the dirt. When it starts to sound like it used to you are done. Let me know how this works out.

your constant power wire is not hooked up or it has come loose that is why nothing will stay saved on the unit have it looked at and see if they wont fix your problem cheap...... its a easy fix

Yes, you must hook the center speaker to a tuner, or it will not work.

Amplifier is about shot, need to replace IC pack or transistors (whichever it has). Could, remotely, be the speaker lines are installed incorrectly?out of phase. + to +, - to - from amp to speakers. Some amps will protect themselves when this condition occurs till fixed.

1.due to some short circuit in your receiver circuit has made the fuses blown
2.Replacing the fuses alone does not get solve.
3. Check the reciever power circuit
4. check whether output is being short circuited
5.Contact service centre

I have the same problem! tuner works just fine. I cant access the dvd mode. i can only access tuner, video input, and rear cam. Ive tried different cds and dvds and it did not help. Also it seems like the ejection mechenism is running continuesly.

There should be some sort of outboard amplifier. Mine had an amp at each speaker, and also a receiver mounted behind the passenger seat. Could it be that the power antenna lead from your headunit is connected to the amp turn-on lead? That way, when the radio is playing, the antenna lead is powered and thus the amps are too, whereas when the CD is playing, the antenna lead would not be powered and thus no sound. Try reversing these two wires (Power antenna and amplifier turn-on) and your CD should work.
