Lowrance HDS7 repair?

[MyKey]

A new fishing friend of mine left his fish finder in boat storage this winter and the display isn't working. Hoping it's still in warrenty but wondered if others have seen this issue. It seems to still pick up fish just can't get the screen to work, it's all fuzzy and flashes.

I had a G2 HDS 7 and it used to turn it's on and off randomly...  I sent it back after 2 years and they replaced with with a G2 touch HDS 7.  I was told I would be charged for it, but they never did...  Their customer service is very friendly but leaves a lot to be desired.
