The model is AN-PR1000
ERR80 indicates a problem reading valid data from the EEPROM at power-on ("Protect area read error").
It is probably necessary to replace the EEPROM to fix this.
It is then necessary to re-set valid values for each address in the EEPROM by following the instructions in the link below:

You may need a repair center to do this for you if you are unable to do it yourself. A Sharp specialist should be familiar with this procedure.
You could try the re-set procedure first without replacing the EEPROM in case it's just a data loss.

Here's a link to the user manual for the remote. There's a section with codes for programming your devices.. Also, it says, if code isn't listed, there is a "code search" function on the remote..
Good luck!
