Fading Display on NAD M3


Hello Everyone
I just noticed that display on my NAD M3 is fading in upper
left and lover right corner. Also letters BALANCE; TONE DEFEAT; SPEAKERS A; BI AMP 40,60,80,100Hz are almost
unreadable. Has anyone encountered similar problem. Is that
just the display or something else.
I would really appreciate any opinions about this problem.
Thanks in advance.

The manual on how to update the M51 is supplied with the new firmware. I do not have a clue how to do this on a M3
I am already in touch with NAD in Austria. Right now it takes more than two weeks. Till now no answer on how to update my M3.

Thats why I joined in. 

Regards
I used to own an M3/M4/M5 and had a similar problem.  I returned the (two week old) unit to my dealer and they did some sort of software update which solved that problem.
In the past I've owned several NAD components and have found they just need repairs, not enough to abandon the brand, but nearly every NAD component I purchased needed repair.
I wrote to NAD quite some time ago. They mentioned that they will get in touch with the "producer" and will come back to me. .....

Can anybody who upgraded to 1.12 send me a manual on how to to it?
