KOSS KS5190 incompatible disk error message
Well I assume you've gone through the usual steps of making sure the discs are clean. Assuming thats not the issue, and If you're lucky, the problem will be a tiny speck of something which has made its way onto the DVD's lenses and stuck there. These lenses are used for focusing and detecting microscopic light beams that bounce off the the DVD tracks. Occasionally you can fix this without opening the unit, using a DVD lens cleaner kit. You can google them and happily they can be found for less than $10. So its definitely worth a try. I often run into this with DVD players/burners in PCs. I guess despite manufacturers attempts to shield the sensitive optics, PCs are notorious for sucking in dust. If the disk cleaner doesn't work. you might go a step further manually cleaning. But I'd try to find a youtube specific to servicing your machine first. Manufacturers are getting good at disguising the procedure to take these units apart. Good luck.
