Question about NAD C521 CD Player
I have a Nad C520 cd Player which works fine but emits a high pitched ringing noise which I located to a component on the circuit board the sound is not throught the speakers it is comming directly from the circuit board I was wondering if anyone has come across this problem before and is it fixable Thanks
From your description, it sounds as if the noise is coming from the circuit that controls the display backlight. If I recall correctly, the C520 has an EL backlight just like the C521 (which I have one of). On the front of the circuit board, there should be a little yellow trimmer potentiometer that controls the brightness of the display. It may be that the noise will go away if the brightness is turned down some. If the noise varies as you turn the controller, but doesn't go away completely, the backlight may need servicing.
