Keypad says its shorted

microwave started going to 1 min timer and starting on its own, I unplugged it and it , plugged it back in, did the resets and it worked for a while. now it says to press clock, when I doo nothing happens the it says there is a keypad short. anything I can do to fix it without calling a repairman or tech?

I have a ge microwave model jvm1540dn1bb its about 6 years old. I tried unplugging and replugging to reset it at first it worked asking to press clock etc etc then later the pad quit responding to anything and scrolled a message that the keypad may be shorted. is there anything I can do to check and/or fix the problem?
