Re: Open-close tray swithc

The only way to solve that problem is to replace the belt to eject the tray

followt this step and fix it. God bless you
However there are a small hole in the CD/DVD burner use clip and make click and open it.
  1. Open the housing by removing mounting screws and anything blocking the tray. Press the open/close control to the extend tray, then unplug the unit. To remove a clip-on tray front, brace the tray and slide the panel to one side.
  2. Unplug cables between the front panel and the interior. Remove any screws securing the front panel and remove the panel. If it won't move, check beneath it for clips or additional screws.
  3. Remove the hold-down on top of the disc tray and gently pull the tray out of the player. Clean the travel rail and guides with a swab dampened with denatured alcohol. Lubricate lightly with white lithium grease.
Remove the drive belt (using gloves or tweezers) to inspect for dirt, water, or damage. Clean with a lint-free cloth moistened with denatured alcohol. If the belt is damaged, replace it. Service a DVD tray motor:
  1. Unplug the player and test the motor with multimeter
  2. Unplug the motor plug and spray it with electrical contact cleaner, then plug it back in.
To remove the motor, unscrew or depress the end of each bale and lift out the motor. Replace the motor if necessary.

CW088D CD-RW Tray ejects with CD in it but not empty

If the tray retracts but doesn't close 100% then it will open back-up. If it is closing fully then returning open then it is a bad drawer switch. It's hard to get to but if you do get in there, a little WD40 lube might help it actuate. Good luck!

PC s/n = 0029975695: The tray will not eject. When

The usual problem with disc drives is a little belt that drives the loading tray. It stretches with age and slips, so the motor turns but the belt doesn't. If you want to take the time to try finding one, the belt is replaceable.

On the other hand, new DVD/CD burners are only around $30, so it's usually not worth trying to repair the drive. It's faster and easier to put in a new one.

Hope this helps. Thanks for using Fixya!

Blinking green light on 1 tray

You could have a faulty drive.
To open the tray, you need a paper clip, straighten it and place it in the small hole below the disc tray, push it in and the tray wull pop out slightly, remove paper clip and pull the tray fully out with your fingers.
Then try to close and open the tray with the push button, if it does not work you need to replace this drive with a new one.
