Default Marantz CD84 tray motor dead?

Hi All



My Marantz CD84 was working perfectly a month or so ago when I lasted used it. I am wondering if the spell of humid weather has caused the problem with the playing most of the cd and returning to the beginning? maybe some oil for the swing arm mech?



Another issue is the tray wont respond. I checked all the jumpers , also took of the belt and tried to power the motor with a AA battery, but there was no respond. I had itinally thought it was the open close button on the tray??



Thank you

Regards

Sam

Check there's power going to the motor. If so it should be a simple replacement, 5v mabuchi dc motor.

Disconnect the motor from the logic feed before testing with a power supply of around 3volts. If no action, replace the motor. If you power up the motor when still connected, damage may occur to the driver stage.

Thanks for the reply Sq, i will look out for the motor 5v dc. The CDE84 wasnt playing again so I think the cables must need checking and the seating of the connectors. Motor didnt work with 1.5v battery so it must need more juice to test

Thanks Jon, yes i disconnectred the wires to test it but not with 3v only 1.5v, I will try again if no action will replace iwth motor that SQ mentioned

This thread is in the wrong place so I'm going to move it to digital source.

Thank you Kevin,

After taking the CD84 partly apart, checking cables etc, the motor is now working, along with lights.
