Just a guess but it could also be the power supply for the display. But I suspect it is the display itself that is failing. Contact NAD it may be a common problem that they may have a fix for.

Thank You much for respond.
The problem is that I recently purchased an Amplifier here
on Audiogon and seller and I trying to resolve the problem.
I really don't know, should I return the Amplifier or to try
to fix it. The new display itself is $210.00 plus $100.00
labor fee. If is the power supply problem it would be even
more expensive. I also contacted NAD and I am awaiting answer
I have the same issue with the M3. It seems NAD may have a quality control issues based on purchases of their products I have made in these later years.
Also, the volume button on my M3 remote became very difficult to engage without continuous pressure on it. It wasn't covered under warranty and was about $100 for another remote.
My M3 is just over two years old and still under warranty but my dealer is about 100 miles away. I will return the M3 for repair in about a week while I am on business in that area.
I have been with NAD about 30 years. Although their products sound and perform great I am moving on to other options in the future.
I just found this thread. I am actually having the same problem. My M3 display is not as bright and hard to read. I noticed that someone mentioned that it was a software fix. Can this be done buy the consumer or do you have to take it in to NAD? If it can be done at home where would the software be and how do I go about fixing it?
Any help regarding this issue would be greatly appreciated.
Firmware update installation will solve this issue by allowing you to push the tone and balance button on the facia at the same time for about 5 seconds and the entire vacuum display will light up and you let it burn in for 48 hours like that. The fading is simply unused areas that don't glow as brightly as the commonly used areas. I had the same problem and this took care of it completely. Contact NAD support and they can email you the firmware to install using a RS232 cable from a PC to the M3.
Bavarian05 is correct - i just did this and it WORKED!
However, it is NOT the tone and balance button you need to press for 5 seconds (this only makes a factory reset), it's the balance and mode button you push down. Here is a short manual, after you've installed the recent software (version 1.9) - you can get it by writing to NAD and follow the instructions in the program exactly.
- Shut down the amplifier totally
- Turn it on and wait for the "NAD M3" logo to disappear and the amp clicks.
- Hold the balance and mode button on the front of the amp until the display totally lids up - if you think you can see words, that is funny enough the functions used the most.
- Wait 48 hours, DO NOT TURN OFF THE AMP.
- After 48 hours, if the amp has not gone back in normal state, you can now put it in standby and then turn it all the way off and let it be turned off for at least 10 seconds before turning on again.
That should do the trick :) if anyone needs it, put your email and i will send the installation file from NAD. Remember to use a USB-->RS-232 DB-9 cable, and installing the driver before using it, then everything will go smooth.
