Threaded Mode | Linear Mode

I was recently given an HP-28S that looks to be in absolutely new condition. No battery compartment corrosion, no broken parts, the leather pouch shows no signs of wear. It powers on and I am able to adjust the screen contrast but there is no display.

The [ON] [<] Test does print numbers on the IR Printer, but the test message says "2 Fail".

Is this something that is repairable?

EDIT: If it is a lost cause, it is worth noting that the 28S leather pouch will hold a DM42 and a DM41X at the same time.
