NAD M33 issues, don't know where to start

I hope this is the right forum to post this in, if not sorry..

I have owned my M33(used) for 3 months now, everything was just fine, then a few days ago my display went out, it lights up, but blank screen. I have tried the factory reset and nothing changes. Everything still works via the remote or the BluOS app, but not having the display sucks, anyone have a fix or any ideas they could share? I was hoping that I hit some kind of setting, but it happened when it was left on for a working in the morning, came back and blank screen. Do I call a repair shop off the NAD website? What would you guys do??


Yes, contact an authorized NAD repair shop.

My sister has a NAD CBEE something integrated amp which developed a fault.

The repair service was fantastic.

That amp has been working faultless for over 15 years since.

I would start by installing the latest firmware if possible.  If it is like some other Mxx products there is a menu to test the VFD screen.   

As far As I know, it's automatic, and I just did a factory reset, but will dig, thanks


Not sure if yours does, but some NAD can be upgraded with USB stick and correct power on sequence.  Like press a button while powering on.  Thats how my m51 updated.   Good luck

OK just picked mine up after a month at the repair shop.
Tech notes are- no characters in the display but backlights present. Need LCD unit in order to correct.


The LCD Display was $332.10 and 4 hrs labor $360

total of $730.17 after  $38.07 WI (USA) sales tax


I talked to the guy who did the repair and he said it was not an easy swap, glue, 2 sided tape, etc.


Also noticed another M33 sitting on the rack, I asked about it and all he said it was different issues and they haven't gotten to it yet.


Anyway I fell I'm still ahead for buying at $4200 used, they are now $5999 new

Don't have a NAD myself, but one item you might check is to remove the case cover and see if all the connections look right.  Computer display screens are typically plugged into the mother or video board using a flat ribbon cable.  Yours may have worked loose.  And check the connection at the display end of the cable, too.  Finally, note the ribbon cable may not have an actual "plug" on the ends, but rather just a stiffer section of cable with silver or gold connectors. They slide into a female connector on the circuit board that has a up/down slider that moves maybe n 1/8th of an inch to lock it down, so are a little trickier to use than a normal plug.

Ouch.  That's a pretty new unit to be incurring that type of repair charge.  I did consider this model.  

I had the exact same problem. Sent it back to NAD under warranty, they sent me a new one although it took 6 months!


How is the sound quality of the M33?  Are these quality defects isolated or common?

I had one for while and found it kind of un-engaging.  Great bass, takes control of the speakers but (for me) it just didn't do it.  Sold it and replaced it with a Gold Note IS-1000 which I much prefer.  No cool display, but the tone seems much richer and the presentation really hooks me.  FWIW.
