EDP Not Working

["Matthew Wiley" <matthewf5@hotmail.com>]

Turned the EDP on and the loop 4 screen came up and everything was normal, 
input was getting signal.  the front panel buttons won't work when you 
scroll through the functions, nothing comes up in P1...P2....the front is 
lit up except for overdub and undo they aren't lit at all.  any ideas?

thanks
-matt
