Sony ICF-CD7000 played a cd just fine. I immediately took it out, put in a new one, and the cd player suddenly doesn't work, just makes vibrating noise.

I've been able to prolong the life on mine by doing this:

Insert the disc, then spin it by hand and quickly close the door and hit play.

It's always worth using a laser cleaner first, as it may just be dirty and stops spinning because it cannot read the disc.

Belt either came off or is slipping. You can open the system up and view it yourself, just make sure the stereo is unplugged.

Hello
Unplug the unit and replug it after 5 minutes or so. Then Hold Down the CLOCK/DATE until a short beep sounds. If this beep sound cannot be heard, be sure that the internal circuit has some trouble, and has to be repaired. Normally, any other button get strucked, there will be no response with other buttons. OK.

It is a circuit fault. Seek tech assistance.
