NAD Audio Players & Recorders - Recent Questions, Troubleshooting & Support

This is the technical solution, you have to open the unit:
Locate IC33 and connect pin 6 to ground, connect power, and then remove the ground connection at pin 6.
The unit will then boot up in factory default.

It sounds like the DVD region (a setting in both your OS and your DVD hardware) may have been changed. DVD regions are the agreed upon method (by entertainment companies, hardware manufacturers and governments) to limit cross-border sharing of media. Most valid (read: non-pirated) DVDs have a region code. Your DVD drive will only play DVDs with a region code that matches the DVD region code set on the DVD drive.

You didn't mention your OS but if you are running Windows XP then go to Start->Control Panel->System->System->Hardward->Device Manager and find your DVD player. Right-click the DVD player and select Properties from the menu and you should see a properties dialog-box with a DVD region tab. This is where you can change the DVD region that your player will recognize. Be careful, don't play around here, most DVD players have an embedded limit on the number of times (4-or-so) the DVD region can be changed.

Hope this helps.

Hi Michael, check inside your NAD C542, there are 4 fuses, check that none is open, if all are well, you could have problems with the capacitors in the area of the power supply or in the case of the Transformer
If you do not have technical capabilities to evaluate the above, consult a specialized technical service
I hope you can solve the problem
Greetings Franco Dosil

Hola Michael, revisa en el interior de tu NAD C542, hay 4 fusibles, controla que ninguno se encuentre abierto, si est?n todos bien, podr?as tener problemas con los capacitores del ?rea de la fuente de alimentaci?n o en el pero de los casos el Transformador
Si no tienes capacidades t?cnicas para evaluar lo previamente indicado, consulta un servicio t?cnico especializada
Espero puedas resolver el problema
Saludos Franco Dosil

To reset the the T743 hold down the video 6 and the source up buttons for 3 seconds. then power up from the back button

Check the rectifier diodes in the power supply for shorts and look at all the filter capacitors in the power supply. Look for puffy discolored and domed tops. All filter capacitors must have flat tops. Check the windings of the transformer for darkened or burnt spots and test for shorts in both the primary and secondary windings

Hi aartman

Yes it does have backlamps.

They are soldered to the PCB so you will need a few tools like a soldering iron, philips screwdrivers, solder, and some replacement lamps. Replace the lamps with this type from Farnell electronics. They have a 15000 hr life expectancy and last alot longer in the unit. I have tried many types of lamps over the years, and found these are the best choice if you want them to last.


To get access to the lamps, you need to pull the main PCB out of the chassis to then get access to the bottom side of the printed circuit board where the 2 screws that retain the white lamp reflector assembly. Change both lamps with the type I mentioned,
6ab9edb.jpg Be careful not to flex the LCD display that is now exposed, it is quite fragile with the support of the lamp reflector cover no longer in place. ... reverse procedure to reassemble and away you go.

I am more than happy to talk about this solution with you further. Just ask away. Cheers

If the take up spool stops taking up the tape, it wraps itself around the capstan and jams up the mechanism.

put a magnet on the side of the relay or you must have a bad cap that drives power to the relay it is getting to much ac to it

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.

NAD Audio... | Answered on Mar 06, 2019

Did you make sure that the wiring is correct? did you make sure its +12V and ground and not the opposite way? If you checked that, please remove the remote wire for testing. If it then doesn't work, remove the wires from the speakers from it and try again. If it still doesn't do anything, bring it to a repairshop.
