My CD changer's disk tray keeps opening up, refuses to play discs
I have been utilizing my Yamaha CDC-665 CD changer for 7 years now without problems. Recently it began opening as soon as I turn it on. When I load discs it does not play them, instead it waits for a few seconds and opens the tray.

You have a problem with the try control circuit. It could be the switch is leaking across itself. Could be a problem with the tray motor control IC, or the Microprocessor is not reseting the open tray line correctly, or theres a cam assembly inside the unit that tells the microprocessor where everything is by means of small micro/leaf type switches thats out of alighnment or broken. If its seven years old, you got more then it was designed for and I would'nt invest a dime or the time into the repair of this unit. Time to take a trip to the electronics store. Good luck

Hi. there is a tiny limit switch that regulates the actual CD platform drawer(The part where you lay down the CD). this switch if faulty. it is designed to shut of the load motor when the CD tray is fully inside the unit.
this limit switch must be replaced. this is a job for a qualified Yamaha service tech. contact Yamaha for this repair.
I've done about 100 CD transports so far. Try changing any belts in the unit. On some CD players ,if the open/close belt is bad, it wont allow the CD to be read either. Also,VERY lightly cleaning the laser lens and dusting the unit out helps too.
If you trust yourself enough to open the case w/o breaking stuff, then open it up UNPLUGGED, locate the laser lens (small,clear,plastic) gently clean the lens with a swab of lens cleaner for glasses. Also clean the chrome runners that the laser assembly tracks on.
