Hi John

Expert:  Pete replied 1 year ago.

First, try a hard reset:

Turn off the unit and remove the CF card and reinsert it again a couple of times.
Then hold down soft button 1 while powering up the unit, keep it held down for about 10 seconds.

Let me know if the unit starts up normally again?

Can't try until next weekend. Any other suggestions?
Expert:  Pete replied 1 year ago.

Other possibilities are the firmware may be corrupt and need reinstalled, or the display has failed.

If a hard reset doesn't work then the unit will need to be sent for repair.
