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 !

Start by searching for internal fuses! Testing for a broken switch. Looking around for burnt or damaged parts. Check the power supply section for faults.

Remote controls have an operating code which entered right will cause all functions to work. However if you were given the wrong remote or it doesn't have the right code, certain buttons will not work. Check that the appliance it operates is the right model for the remote. Some remotes will allow reprograming others are fixed. If you can reprogram it will be just a question of finding out which code the amp uses and entering that. You can search online for the codes for your model. It's not uncommon for the wrong remote to be sent out when first sold. Some people don't know it's wrong as the remote works nearly all the functions, just not all.

Try a factory reset of the receiver. To perform a factory reset, press and hold the MENU and SOURCE buttons until Factory Reset is displayed. Then Power Off from Back panel for 1 minute and power up normally. You may have damaged the receiver if you did not power off before installing the Onyx module.

If you have cables running to speakers, ensure that the cable's have not been disslodged, broken (need a circute tester). If the speakers are within the unit, I suggest you get a technician to check it out or serious damage can be caused. Last suggestion is if you have the manual or can get one, read the setup instructions. Good luck.
