Mount will not power on or boot up

David Woolf

1100GTO will not power on.  Main battery shows 12.76V and backup battery shows 12.5V.  Keypad simply says "Astro-Physics Ver: 4.19.3" and will not proceed beyond that point.  Reads drawing 0 amps and LED light on GTOCP4 is not lit.   No change with Regulated Power supply.  Is there an internal fuse or a reset procedure?
