Audio Systems: Koss KS3102, model numbers, reset button

Question
Well, My koss has been running great.  I recently bought a new samsung 23" lcd screen and was all pumped about watching movies on it.  As I was using the koss menu to set up the system, I accidentally changed the mode to pal from ntsc or something and now the screen can't receive the signal.  I can't open the menu to change it back and I just want to hit some reset button but I don't have my product manual.  Plese help me.

Answer
I will need model numbers for the Koss and the LCD monitor so I can look them up.

You can probably find the manual at the Koss web site.

It might reset if you pull the power cord for 30 minutes then power it up again.

I will await the model numbers.
