Hi, I think you refer to the lcd display that does not work. Have you tried to check if the info is displayed ok on a pc using for example the program rotator distributed with HRD (via rs232) ?
In that case the issue could be in something wrong between the pic and the LCD display connections.

potentiometers and wiring between the Yaesu control box and the rotors are
probably OK. If not, check for broken or corroded control cable wires and
2. If the meters work, then check the wiring and connections between the
Yaesu box and the LVB tracker.
3. The next thing to worry about after connections is the 5-volt
regulator and analog outputs from the Yaesu that give the position to the
Check the above, then let us know what you find.
