The RCA Rs 2650 stereo i have will not close. There was a cd that had fallen back but that has been taken out. The stereo still wont close or open..?

SOURCE: buzzing noise

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).

Does it have problems spinning up the disc, so that the disc will start very slowly, like if it didn't have enough power to spin?

If so, the problem might be oxydized brushes and commutator in the spindle motor.

One way is to replace the spindle motor, another way is to clean it (which is not very simple, but it's also not impossible, so if you think you need to clean it and you want info on that, just post me some feedback, i can explain the procedure).

Another thing to check is the door closed switch (you might want to do it prior to dismantling and cleaning the motor, it should be somewhat easier). If the door switch doesn't get activated or if it doesn't work properly, the CD will not start spinning at all.

If the door switch does not get activated when you close the door, then some part of the door that activates the switch might be bent, broken or otherwise damaged, and if the switch does get activated but doesn't seem to make a proper contact, then either the switch has oxydized contacts or it is damaged and needs to be cleaned or replaced respectively.

You can check the switch with a resistance measuring function on a multimeter - it should show just about zero ohms, a few tenths of an ohm maybe when the switch is activated, meaning that the switch is good.

You can also check it with a continuity (diode) test function on the multimeter - it should show about zero millivolts, maybe a millivolt or two voltage drop or give a sound alarm when the switch is activated, again meaning that the switch is good.

Other causes may include problems with electronic motor controller IC (chip), problems with power supply, bad connector contacts or bad solder contacts, just to name a few.

I hope this helps somehow.

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.

Testimonial: "A motor is running when i hit the door open button. A humming loud noise. Will take apart and explore and keep u posted . thanks"

Remove the case screws on the left and right side panels. Pay attention to the long screws that come out of the middle of the panels to make sure they get back in the right spot. Remove one screw from the top rear back panel. Lift side panels of in a hinged motion from the bottom. Remove the top panel in a hinged motion from the rear. In the center of the disc tray remove 1 screw from center. Note the orientation of the tray for re-insertion. Lift the tray up and out. look for small dc motor and spindle. this motor is used to spin the tray. You should find a black belt between motor and spindle. Make sure it is in good condition. Look to the right rear of the unit. there is a second motor and belt which drives the tray. This belt may be broken or off its spindle. repair or replace the belt as necessary. Plug the unit in and test the open/close function and ensure the gear train, belts and carriage move smoothly. reassemble.
