I press "clear" and shortly a message reads-"Sharp the best demo"
Everything else works.
The
first thing I would suggest is a hard reset. Unplug the unit for a
minute or so. Then plug it back in, set the clock and try again.
If that doesn't work,
leave it unplugged for maybe an hour. Then let us know if the hard
reset does not fix it.

It sounds like the magnetron may have
either failed or is not being supplied with the extremely high
voltage required to run it.
YOUR
SAFETY IS PARAMOUNT
This is a job for a professional but if
you are safety clued up, here's instruction.
Make sure the !!!!any
capacitors are discharged!!!!! before attempting any sort of
repair.
Check the door interlock switches first then the high
voltage diode with either an AVO model 8 or moving coil meter on high
resistance range for short circuit, (DVM's won't show the fault!),
the capacitor can fail and go short circuit, the feed fuse on the
primary of the high voltage transformer and then finally, the
magnetron is best checked by substitution.
Hope that helps.
