i was out the other day and when i looked up at my lowrance 113, as the screen was coming in it was all white i wasn't sure what was going on, the unit is only 2 years old and i just replaced the antena this year. i went down to check this issue out and it looks to me that the soldered wire on the fuse block is lose and if you hit it just rite it will shut the unit down. what should i do i'm no electrican?
