you could have a shorted speaker I would disconnect all speakers and test them 1 at a time to see if you can get the amp to make some sound before I did anything.

Myryad ma120 power amp,loud pop when switched off


Sounds like a Electrolytic capacitor has failed. Search backwards from the speaker connections inside the unit to the main PC board. Replace the first ones that you come accross that are linked with the speakers.

My rear and center speakers suddenly quit working. No sound


try a different source. if there is output on all speakers in test mode, then the amps are good but the source or source switching may have a problem.

Kustom Profile One 100w PA -loud bang!


i have three of these in my amp repair shop. one of them does exactly this. as well, the other two are suspect to the same issue. i believe it is low quality leaky or shorting caps. are you using the xlr inputs or 1/4 inch inputs? so far, these are working good thru the 1/4 inch jacks, but the xlr inputs are squeely with feedback and i get that loud bang/pop from one of them. kustom wants me (my shop) to be an authorized repair station for them. i want to be able to resolve these three amps before i accept. if they are a nightmare to deal with, then i will tell them no way.
i will post back with in the next week with more results and hopefully i will have precise solution with parts and procedures.

LOgitech x230 - problems with sound


If the sound only happens when sound is being played through them I would check the shielding on your connections to your sound card. Make sure that any protective coverings are in place and that the connections are tight.

If it happens at random times even when sound is not being played through them I would see if you are picking up interference such as a close cell phone, fan, ham radio operator, etc.

Nad c370 problem....


Hi arda5
Did you try swapping speaker connections left for right on the back of the amp to isolate the problem. If the fault stays with the speaker, then that is where your problem is. Try this and get back to me here with the results.

maybe the first step could be checking the subwoofer's fuse.it is located over the power supply connector.
