See one version of the owner's manual here:
http://www.amano.com/timeweb/PDF/HP3000_M.pdf

There are some dip switches on the back of the unit which can be used to reset the unit to factory defaults, switches four and five are used to retain the user data or fully wipe the machine to factory specs, respectively. If you have tried those and the unit still fails to display properly, it has a defective logic board or display panel and will need to be serviced.

The one I have does not have DIP switches. just the single white reset button at the back. If it is indeed the logic board or the display panel, would it be possible to try and repair it on my own, or should I just salvage the parts for other HPs that come in for repair down the line.

Thanks!

It is always worth taking a look inside the box to see if it is something obvious that can be repaired. A cracked solder trace or a burst capacitor, etc. There may also be some places that repair stuff like that relatively cheaply. The dip switches may also be beneath the cover, so take a peek and see what you find. Maybe you can become the place others send theirs to be repaired...otherwise there are lots of independent repair shops such as http://www.providenceindustrial.com/ that are able to repair these things for you much cheaper than replacing them.

Thanks for the input. I am going to give repairing it on my own a shot!
