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.

Need the code for a Panasonic TV remote to operate KS3102

I found a few manuals that may have a similar model number but none of them contain the Koss Receiver, you may want to try a few random receiver numbers and see if anything works, these are all the universal codes i could kind for koss receivers:

Salutations robn7499,

There are a few things that may cause this to happen. First I would check your connections for your center channel speaker. in movies with 5.1 surround sound almost all the vocal tracks come out of the center channel.

Otherwise there maybe an issue with the volume levels for the center channel as well, these can normally be adjusted through the setup of your home theater system.

I hope this helps.

Sound but no video

Run your yellow cable from the DVD player directly to the TV in the port connected to the red/white cables. If this is already done or doesnt, work, let me know

Had the same exact problem today. Called and e-mailed Koss today and was told player was made by Koss Electronics, not Koss headphones and that Koss Electronics went out of business. Finally just started hitting random 4 digit combinations and would you believe 0000 works? lol
