Default Marantz CD42-The disk ejects but it is not closeing up...

Hi, Has anyone experienced the problem with this model where pressing the open/close button will not close up the tray?
Pushing the tray in manually will (only) get it to close.

The TACT switch on the main board is ok and the Micro is seeing it.
The motor and orange gear wheel look all ok.

Can anyone shed some light? Cheers.

You may have greasy motor (inside - could be greasy commutator / semi shorted - requires high current to “get going"), or insufficient current drive (usually an OP with complementary transistor pair as the current boost), or slipping belt.

The uPC is seeing the button press, I recon follow the signal from uPC towards the tray motor: check the motor / belt / current drive.

Good luck,
Boky

If you read more closely you'll notice the button reads 'open' not 'open/close', hence this is user error, or a classic case of RTFM, don't blame the CD-player! To close the tray simply push it gently, or press the play or any numerical button to select a track directly.

Best regards,

Or push the actual switch sitting below the tray on the face plate, that said "open" button mates with when tray is closed. Ie, the switch is an open close switch but as the button part is on the tray it only allows open.... you get what I mean I hope.

Had this stupid open button on my CD850, used to push the switch below the tray on that one....

Same thing on my Marantz CD62

Just use the "Play" buton. I wouldn't advice pushing the tray back, even gently. The tray gears already break after a few years of normal use, don't put more stress on them.

Default Ah ha!

Yes. Pushing the tray in does start the loading sequence up.
It also makes sense to use the play button instead.
After obtaining a copy of the S.M. I checked the entire data/drive path right up to the tray drive motor itself. I could not fault any waveform from the manual and now all is making sense. Not a bad sounding old player.
Thanks everyone for your posts...
