NAD 705 out if order

I just purchased a used NAD receiver model 705 on eBay. The unit is not working at all. It will power on (the power led turn on and I can hear the relay clicking). The tuner display won't show any thing. The amplifier section doesn't work. I check all the fused inside and they all seemed to be OK. Any advise for trouble shooting.

These are EXCELLENT receivers with GREAT FM tuner. Worth fixing. And the fix is super simple for someone who knows how to hold a soldering iron. For instructions how to fix the display (with pictures) see

As the display lights are blown, you can't see that the unit is in the wrong 'listening' mode. USe the Listen switches to get to the input you are tring to use. The blown lights can be replaced with White or Blue 'wide beam' LED's, one leg connected in series to a 6k-ohm resistor.

    I have done this repair and it LASTS -possibly my favourite reciever ever after 21 yrs.


The LED's inside the display are burnt out, thats all. When the green light is on the unit is in standby, ITS NOT ON. I just picked up one for $10 with same problem. Try to get something to shine on LED and you can see LED and switch it to the input mod you want, you'll quickly find out its ok. Good luck

This seems to be continuin problem with those. Not sure of exact fix yet, but believe it is just a fuse or bulb that needs replaced.

I have owned an NAD 705 Receiver for many years, and am just now having problems (probably over 20 years old). I'm getting a message on the screen of the receiver that says 'protection' .

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.

NAD T741 goes into standby by pressing power. It turns on after selecting a source button or by remote. but after 6seconds it turns itself off with a blinking power led. Pressing the sorce buttons gives...

I just had the same problem wit my T741. It was a malfunction of the DSP motherboard, not a repair for amateurs. Repairs at the Dutch NAD importer cost me about 130,= euro.

The unit will not stay on

I got similar issue and managed to fix it with excellent tech support from NAD. Flashing LED means system goes in to protective mode. Most probable reason is presence of DC voltage on amplifier out puts. In my case it was both surround amps. It had faulty resistor and a dry jpint at power line

My Archos 705 is not turing on.

704/705 will not power up at all without a bettery that has a little charge. If these batteries are not used they have a tendancy to die. you could try charging it on a DVR for a few days. then when you disconnect it from the DVR immediatly connect it to a DC charger and your lights should then work. Either way I would consider id a warranty claim.

NAD T751 constant buzz

It is a known problem with this model. The source of the buzz is the Dsp power supply. On the DSP board itself there is a 2200my\f/16v capacitor that is defective . Usually the capacitor will turn brown and swells due to overheating. Replace it with a higher temp rating capacitor with the same capacitance and voltage specifications.

Can I connect a power amp to this unit?

If your 2100ES has a selectable INPUT AND OUTPUT and if you're intending to send all signal to the power amp, i.e. not bi-wiring or using the 2100ES to run mid-range or treble then you simply send Left & Right audio (White & Red cable) from a 2100ES output, probably AUX OUT ( it doesn't really matter apart from Phono on some units) straight to the power amp on AUX IN.
We should be just dealing with audio here, so connect the NAD audio output to CD or DVD IN. Select CD or DVD IN on 2100ES input switch and switch output to AUX OUT (whatever you decided goes to the power amp) on the 2100ES. Turn power amp to AUX IN and it will now get an audio signal from the 2100ES for amplification.
Speakers connect to the power amp as a normal amp, so pos and neg etc. The 2100ES now only acts as a signal feed, the power amp does all the work.

So, summary - switch on the NAD, press play - video goes separately and audio goes to the 2100ES. Turn 2100ES to INPUT for NAD. Turn 2100ES to OUTPUT allocated for power amp. Turn INPUT on power amp to allocation for 2100ES.

Turn it up!
