Screen freeze on Lowrance Elite 4 HDI

[Fishin' Magician]

I was getting all set to head out tomorrow to try for some yellows or maybe even the elusive bluefin tuna and wanted to test out the FF just to make sure that it was working. Good thing I did. It went through it's normal start up and then suddenly froze up. None of the buttons worked and it wouldn't power down. So I finally had to disconnect the battery. I tried it a couple of more times, but each time it froze on the opening screen and wouldn't progress any farther.

Anyone had the same problem? How did you fix it (assuming that you did). it's only 6 months old, so I'd hate to think that it's already dust. Right now it's nothing more than an expensive paperweight.

Any suggestions would be greatly appreciated. Thanks in advance!
