Hi guys,
I'm hoping someone on here can give me some advice on my humminbird 757c. I think it got some moisture in the unit. It has since dried out but now the screen just shows lines once it powers on. Any suggestions on fixing it? I don't have it in the budget to buy a new one so I was really hoping to fix it. If not i have the transducer and other parts related to the fish finder if someone can use it. Send me a message.
Thanks for any help or advice,

Jason
