perfect pass display going out

last weekend my PP display started going on the fritz. worked fine saturday, get out there Monday and it wouldn't show current speed or anything. just completely blank screen. we shut down after a few sets and it came on next time we started. I realized that its still working, but the screen is out. beeps when set, holds speed perfectly. just can't see anything.

likely OEM from 2006. can I just replace the screen? have no interest in upgrading or having some whiz bang feature, just want to fix what I've got.

Multi line display BTW

whats going on with it?
