This fish finder I got ain’t turning on no more.
Had it out couple weeks ago where the battery died while on the lake, it died kinda fast ish (about 3 hours after a full charge) didn’t think much of it.

Possible water damage but these things are sealed pretty tight.

Tried turning it on today but nothing. Took it apart and checked the board for any char but it looks fine, checked with a volt reader and it’s getting power. (Average about 4-5V with it just connected to the battery)

Batteries got charge too and is clearly sending electricity, but the screen stays black.

Bit of a novice with this kinda stuff, anything will help, thanks yall.
