AT A STORE THAT SELLS BATTERIES

The only place to get that screen is through a Furuno authorized dealer. The unit is sealed and gas filled to remain waterproof. You're best bet would be to send the unit in to Furuno for repair. You wont save much doing it yourself because the cost of the screen makes up most of the cost of the repair. They will also make sure that all the software is up to date for the new WAAS satellites that recently went on line.

Have you tried adjusting the contrast? On that model I believe you tap the power key while the unit is on and you will see 2 sliding scales on the screen, one for brightness and one for contrast. Up or down arrows select the scale and left or right arrows adjust it. If the contrast and brightmness aren't tied into the power key on that model, they're somewhere in the set up menu.

If adjusting the contrast doesn't help then the screen has most likely failed. This is commonly caused by old age, however repeated exposure to extreme heat or cold can cause premature failure.

Possibly voltage too low, faulty unit, no power coming to the unit.

The GP31 manual doesn't mention language change

whereas the GP33 does

Try doing a Factory Reset and see if you are offered language at first Start Up?
