If the speakers are all good and wiring too, then it's likely that a fault has developed in the main amp section. Till this is cleared the protection will not go away.

the lamps i use on all NAD displays(and have done since the early 1990's) last heaps longer.You can get them from RS components in your country. They are a 14v 37ma type, and seem to last. Never had any come back for replacement again. P/N 351-9585. Increasing the ballast resistor where fitted by 25% in valua also helps preserve them

I have the same problem!

Apparently their is a ribbon cable on the tape drive mechanism that tore because of samsung's crappy design that ribbon cable sends a signal form the tape protection switch.

Since the ribbon is torn and the circuit open the camera thinks the protection on the tape is on

if any one knows where i can buy samsung parts, please let me know

SOURCE: Remove the write protection on 2GB USB Kingston Data Traveler 100

Found this on Kingston site, doesn't help much but may point you in the right direction.

Unfortunately this unit does not have any security or write protection feature. If you receive a write protection message with this drive, check for the following:

  1. Verify that you are allowed to write to removable storage devices. There may be a security setting in the OS that disables write access to removable storage devices.
  2. Make sure you have not enabled write protection on the drive by using a third party software.
  3. If none of the above apply, the drive may be defective.

My NAD T747 keeps shutting down in Protection Mode at 6db when it used to go much louder. I cleaned the unit. Still nothing.


Modern AV receivers such as your NAD have protection circuits to prevent damage when there is a short on the speaker terminals. Look carefully at the speaker connections on the back of the AV receiver- for example, the speaker cable for front left speakers labelled + and - : there should not be any stray strands of wire that connect from + to - ; this would be a short circuit. Check each of the connections on the AV receiver as well as on the back of each of your Speakers themselves. Also ensure all connections are snug (do not use pliers). If this does not solve your problem, you may need to take your AV receiver on for a service checkup. Good luck !

Nad C350 2 channel Amp continually in protection mode


That could indeed be the issue, but you must check your speakers, wiring, and also the oupt stages for problems. Maybe the prtection circuits are actually doing their job. lol

Hope that helps...

Assuming the protection circuit is not faulty, I would look to the devices on the heatsink to the cause of the fault.

Nad c370 keeps switching off


Check the speaker wiring for shorts, a common problem. If everything checks out there may be bad solder joints on the main board especially in the output stage, or there is a fault in one or more driver transistors.

NAD M3 power light turns red immediately and PROTECT message displays. Amp keeps functioning but volume control doesn't work up or down.


Hello
Check the connection to speaker with this amp, for any short or any other fault. disconnect the outputs, ie, speakers from the amp, and switch it On, and see the protect display comes or not. If it comes, the fault is internal and the set need service.
Your M3 dual Mono integrated amp, is of high output power and its outputs are protected against any overload or short circuit. If the system detect any among this condition specified above, it will show protect mode display.
Never load this amp, as protection display is there, as it may damage the speaker or its internal power amplifier section circuits, may cause more money to get it repaired. OK.

The manual would suggest you have a problem.

Try unplugging all of the speakers and see if that amp is still distressed. If it looks clean and happy start adding speakers until it returns (or not).

NAD 712 Display unit


On my system the bulbs burned out some time ago. Today, I bought a pair of 12v micro lamps at Radio Shack (part 272-1092). Then removed the board behind the display and replaced the bulbs. This required some soldering. The bulbs have held up for more than 6 hours, so I do not think they are going to burn out.

Amplifier is about shot, need to replace IC pack or transistors (whichever it has). Could, remotely, be the speaker lines are installed incorrectly?out of phase. + to +, - to - from amp to speakers. Some amps will protect themselves when this condition occurs till fixed.

Power light switches to red.


I suggest rechecking the speaker wiring in case there is a small "whisker" of wire touching either the case or adjacent terminal, also check the speaker end of the wires for same. Do you have a pet? I have seen wires chewed partly through by cats (& rabbits)! See the information from the manual below: http://207.228.230.231/manual/NAD-C370.pdf
