I have a Pioneer 302D, 3 disc tray, dvd player. The disc will not advance in the tray. I have advanced the tray but, I cannot find the disc. Any suggestions?

You should be able to open up the case using a screwdriver, at which time the missing disc should be reachable.

Warnings:
* Opening the case may or may not void your warrantly, if you still have one.
* Make sure you don't lose the screws.
* In the future, make sure you "seat" the dvds in the exact center of their trays. If this problem occurrs again, your player may need to be repaired.

Good luck.

I'll give it a shot and let you know how it went.

Thanks Bud!

Problem solved!!!!!!!!!!

After removing the outer case, I was able to free the disc. I noticed that the inside of the disc had some glue on it which was prohibiting the player from disengaging the disc.

Da!!!!!!!!!!!!!!!!!!!!
