Do you really mean that it won't turn on?

    I have The Nad connected to the computer via usb and when listen some music in the internet browsers after half an hour no sound coming out until I switch it of and on again.

    After looking at your owner's manual, there is no delay function. As long as it as input, it should stay on. Do you have another amp or TV to check to USB audio output? I think it's your computer or settings that are the issue; possibly software related. You could also try the NAD on another computer system. That would certainly narrow the issue down. I would use a scope to keep an eye on the audio, but I'm sure that's not a possibly for you. If you would like to inquire about repairing the amp, please visit my website at audioserviceclinic.com. You may contact me there.

Just says going to sleep


I will assume that you have already try this monitor with other PC nad also try new VGA cable but still getting the same result. Then the problem will be inside the monitor which you will have to open it up and inspect the inside for failed components. Most common failure in the monitors are capacitors in the power supply section, see some pictures here as a guide to what to look for: http://s807.photobucket.com/home/budm/allalbums

Very loud hummimg and crackling - even when volume turned down.


There are a few variants for this model depending upon the serial number. From your description, there are some capacitors in between the amp stages called coupling caps that are failing. The hum is some DC current being passed through the output stage. The crackling is probably just dirty controls.

NAD 3150 doesn't play any sound


I, too, have the 3150 and have experienced problems with it. With me the INPUT knob is touchy and needs micro turns sometimes to get both channels to come through. Also, it sounds like the pots are dirty as I get a scratchy sound while adjusting the knob. I have been told that these units are great middle of the road audiophile units. Actually, for the price of a used unit you can't do better. I just had an NAD 2400 THX amp delivered today and am using the 3150 as a preamp. My girlfriend is not feeling well and sleeping in the bedroom, though, and I can't listen to it :( The few minutes I heard of Steely Dan's Cousin Dupree made me bout **** myself (until I got the dirty looks). Sorry I wasn't more help! Goooooo NAD!

Need user manual for setup of the amplifier.


It should say next to the speaker terminals what impedance of speaker the amplifier is rated for. You can drive any speaker within reason with just about any amplifier as long as you are not trying to attain loud levels. Here is a link to the service manual for your amplfier. It states in the schematic power ratings for 2,4, and 8 ohm speakers so you can assume that this amplifier is compatible with those impedance speakers. NAD is generally known for their beefy amplifier sections. http://www.scribd.com/doc/7234868/NAD-3020-Service-Manual

Nad c372 prob


The unit is detecting a problem and shutting down in what is usually called "protect" mode. Look for bad connections on the board near the voltage regulators.
