Hello:

Is anyone familiar and able to service a CDM4 transport mechanism and Decoder board from a Beomaster 9500?

I have a mech that died recently. It stopped playing with the motor going into high speed rotation. I tracked the problem down to a bad transistor driving the spindle motor. After replacing the motor drive transistor pair, the fusible resistor and  a transistor that the failure took took out on the -9V power supply off the decoder board, I am unable to get the mech to function.

It's a bit beyond me at this point.

If someone on the forum has experience fixing this and is willing to have a look at it, please let me know.

Would love to have my 9500 CD player working again!

Thank You,

 

Derek
