Check the capacitors in the power supply and replace the ones that are large and/or leaking. They usually look puffed up on the top. Also check the solder connections on the power supply. Very common with these "KOSS" units.

Not much info on the device but check the scart lead by substitution, also they often loosen causing problems so reseat both ends and
check in the setup menu that you have selected the correct audio on the output.
Also does it have a headphone socket? If so plug in your headphones to see if audio is on that.

Some Koss players are locked to only one region/zone so this might not work. Try this.

1. Turn on the player (without a disc inserted)
2. Press MENU
3. Press 1, 6, 7, 1, 9
4. A menu should pop up
5. Press OK
6. Press the button for the desired RC (0=code free)
7. Exit menu

Either there is a disk jammed inside or the player mechanism has failed.

Get a Universal remote and look up the code for your DVD

Set-up (Programming) procedure is too much to type in here, and is not practical and it will differ brand-to-brand remote controls. If you wish to get more; check the sites linked here. The site has set-up code list & set-up procedure to many popular brand remote controls. The site has general set-up codes to check with TVs and other devices are given, in the order of the 'device's brand name list' in alphabetical order. Set-up code list to many brand remote controls also is given. Pull up older posts. Search the sites by type in the brand name to your device in its search box at the top right part of the display window. It will help you to find the document easily. http://homenol.blogspot.com/ http://remotesearch.blogspot.com/ http://electronicshelponline.blogspot.com/ http://electrohelponline.blogspot.com/ Programming Notes • If your device does not respond to the remote after trying all codes listed or your brand is not listed in the code list, use the Auto Code Search method to program your remote. • Sometimes the first code that "works" with your device may operate only a few functions of your device. There may be another code in the code list that performs more functions. Try other codes from the code list for more functionality. This is a trial and error procedure; and quiet time consuming. You might have to check different codes said for your device.
