SOURCE: Can i fix the tray on Yamaha CDC-585 that will not close?

See if the tray motor drives a belt to move the tray, if so, check if the belt is loose or broken and replace if necessary.

You can find replacement belts in electronic part stores and on internet, you need to measure the diameter of the circle that the belt forms so you'll know what to purchase, but keep in mind that the new belt will be of a slightly smaller diameter than the used one).

Also check the tray homing switches for dirty contacts or physical damage and clean/replace if necessary.

These switches are usually of a touch contact type (something alike relay contacts that are being pressed to make a contact when the tray is in either of the extreme positions - open or closed).

It may as well be something else like tray motor control section, loose wires or connectors, physical damage to any of the tray drive gears or other tray parts, a stuck/obstructed gear... i only described two of the fairly common problems that often cause the tray mechanism to fail or malfunction.

Hope you can fix it...

SOURCE: The disc tray of my Yamaha cdc-745 CD player does open properly.

It's the belt inside the machine - open tray and look in front left side and you will see it. Easy to change out with new one.

How do you replace the belt drive in the Yamaha CDC 615?


The drive belt on my CDC-615 stretched out this year too, and needs to be replaced. Unplug the CDC-615 from power. Remove two screws on the left side of the housing, two screws on the right side of the housing, and one screw from the middle top of the rear panel. This will allow the top panel to be removed.
Temporarily re-connect the CDC-615 to power and power it on. Press the "PlayXchange" or "Open/Close" button, which will drop the laser pickup/play head and spindle, and start the open/close motor. Power the CDC-615 down while the motor is running, to leave the laser pickup/play head and spindle in the "down" position. You should now disconnect the CDC-615 from power once again.
From here, you can simply push on the CD tray from behind, until it's in the fully open position. This will reveal the drive wheels (one large and one small pulley) just beneath the tray on the left side, with the tray facing you. This is where the replacement belt goes.
Reverse the steps to put it back together.

I have a cdc 675 CD changer, When I close the draw it stays close about 10 seconds, the display reads "open" and it opens back up whether there are discs in it or not


It's reporting that it (correctly or incorrectly) detected that the drawer has not fully "closed", i.e., it thinks that there was a "jam" while the drawer was sliding towards the "closed" position.

This sounds (pun intended) like you need to take the unit to a qualified audio/video technician, to trouble-shoot, and maybe check the "alignment" of the drive-tray.

The gears have probably come out of sync, meaning the tray is riding on the limit switch. You need to remove the deck, dismantle and re-sync the drawer mech. Check the limit switch isnt bent, it's quite flimsy

Hi,

The most common problem is a slipping belt.
You have to open-up the player to check it.
If you're not familiar with it, then please don't.
It's not such a big problem, look for a local repairshop.

Disc door keeps opening.


The drawer belt may also lift the laser up to meet the CD . If the belt is bad , the CD player will kick out the CD.

Cd Tray


Hi Fred..

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.
