I had the same problem with mine and the fix for it was to replace the Q401 transistor on the main board. I used a NTE382
replacement and has worked fine ever since.
Hope this helps

There was a possible solution to a buzzing problem posted on here earlier. Mine buzzes, whirs and whines because of a defective cooling fan. No solution other than to spend $150 to fix or buy a new system for the same price (NOT RCA).

My rca rs 2657 cd changer is stuck. door will not open. any ideas how to correct?

If you hit the open button and you hear a sound like a motor running than it is most likely a belt or connection that physically opens the tray. You'll have to take it apart, locate the cd player and check from there. If no sound of a motor running when the button is pushed then the motor is probably bad.

Buzzing sound and can't open stereo

Again RCA stereos **** for this factor, cheap transformers, replace the transformer and see if that helps as it seems to be the most problem with most RCA systems I've repaired in the past.

Buzzing noise

Of course it will stop buzzing when you mute the speakers. From the limited description, it could be anything from a power supply to loose wires in the system between the speaker leads and the motherboard. Best bet is to take it in to a technician and get a pro's answer. If he wants to charge more than what it's worth to you, get a new one.
