I have a Koss Surround sound(KS3201 is the model number) system and it is from 2004, it recently stopped outputting video from the DVD player, and then sound all together. What it can do is be used as an AV switch so i dont have to unhook my PS2 every time i want to use something else that uses AV cords. Does anyone know what i can do/try to fix it? Or is it just because its not high quality and it just died. I have tried the speakers on a different stereo and it works but that is just a regular CD/cassette player so its not good for me.
