My cambridge cd player 640c not able to close and keep opening, any advice?

Check inside with the power off to see if the belt that drives the tray has come off.

Might be as simple as cleaning the lens

The disk drives in the 640C/740C are Sony. Most people renew the laser, but that is tricky dealing with static electricity. Try renewing the flatcable from the laser unit to the servo circuit. Cheap. If this does not work, you can always renew the laser as well. Beware. There are (Chinese) non Sony lasers on the market. Success!

Half the battle can be won by just dropping a CD in and pressing Play. It WILL close.

Hello,
I have the same problem with my 640C.
Is yours solved? Tell me please.

the set is not loading because the loading action is not getting compplete. please look into the loading drive and correct the loading , check on the drive. if after it had loaded the cd is not loading the drive then check also onthe belt drive, clean the lens of the optical drive because if so it will not read and so stop action.
change the head if the cd is not turning or if it totate and not reading. Helpful? Good day

its a soldered in bulb, sometimes hard to do (cramped area), but if you are handy with a soldering iron you can try, I think the bulbs are 12volt.
you'd have to remove the old bulb to match it online or at radio shack

Try resetting the CD (Cambridge soundworks) by unplugging, then repluging. Then hold down the eject button while you turn on the power.

I have exactly the same thing. I am on my second one too.
Mine is an australian model purchased in Sydney.
