My DVD tray on my Yamaha DV C6480 (it holds 5 DVDs) got stuck in the half open half closed position. It may have come off the track. I opened the case and reinstalled the DVD Tray. Now the tray...


This happens to us all the time. Here is the note I keep on how to fix it quickly:
When tray gets messed up, the drive wheel (with pegs that interlock with pegs on the tray) needs to be such that the tray slides in and out freely. Push tray all the way in. Turn on.

Hope that gives a hint.

Disk stuck in Koss c928. DVD powers up and says waiting. How do I get the disk out and how do I reset unit


There should be a small hole on the door of the disk tray. insert a paper clip in the hole to manually open the disk tray. remove the disk and see if the tray will open and close normally. If it does put another disk in and see if all is well. If not I would have a repair center look at it.

I am getting the locked display


Hi Blackhawk,
This sounds like you've accidentally set the "tray lock" feature.
You can set this to stop unwanted tray ejections:

I hope this solves your problem..

Koss KS2503 "MSG 04" problem


I had this MSG 04 problem. Opened the player up. Messed around. Figured out that the 5-disc tray was hanging up a little during the initialization. The issue is that the tray screws into and rotates around a stand-up beam. On the underside of the tray are gear teeth which are spun by a gear on the main unit underneath. The real culprit is the stand-up beam in the very middle. It is too long. The fix is to first try just tightening the middle black screw holding the tray onto the stand-up beam. If this tightens and MSG 04 goes away, you're done. If it does not tighten at all or much at all, then remove the screw (actually a bolt) and using a razor or sharp blade, scrape the top 1/4 millimeter off the stand-up beam. Apply some grease around the beam and on top. Note, you may have to remove the tray to do all this. If so, that is the most tricky part. Carefully lift on the tray on the front side as you rotate it. Try to free a disc circle edge over the top of the front DVD cover and free the tray. To re-set the tray, put it on the stand up beam with the front side of the tray slanted up and slowly rotate while setting it in and down. After re-seating the tray, screw the bolt down but do not tighten all the way. Tighten it enough to allow rotation and enough to rid the msg 04 problem. I shaved my stand-up beam and have never seen a MSG 04 since.
