echoplex problem

["Matthew W. Prull" <prullmw@whitman.edu>]

Anyone know if this a fixable problem on an older Oberheim EDP?  Any
suggestions would be appreciated.

Problem: Sound passes through, 3 pots are very loose, they do work, they
do control volume and mix.  When turned on, the word loop and a number 33
continuously moves across the screen and does not stop scrolling. It will
not record a sample, parameter and function buttons do not work and
neither do the lights under them.
