THANK YOU! THANK YOU! THANK YOU! THANK YOU! THANK YOU! THANK YOU! We have a Koss DVD Player Model #: KS3102 . . Your instructions worked EXCELLENTLY! I too think it is a problem with the refresh rate. 50~60 hz incompatibility. But once it happens - you can't read the screen - very bad! . You said: To fix this turn on your system and the tv. hit the menu on remote push down 3 times then push to the right then hit arrow down then push ok. You are most-excellent-Nerd! Be Happy DONALD!
I and my wife own a koss ks3102 home theater system. I enjoy watching old movies that are ignored by NETFLIX. Be happy, DON.
