Does any one know of a electronic repair shop that can work on a Lowrance HDS 9 Gen 3.  My on / off switch does not work all the time.  Thanks   Mike

Have you checked with Lowrance directly?

Always try washing electronics in warm, soapy water.

 

Just kidding.

Where are you located?

Lowrance is a big N-O for me.  I spoke with 5 people total, 4 of whom told me the charge to diagnose & repair, how to send it to them, etc. ... and the 5th (an actual technician) telling me there's no way they would repair a 4-year-old unit.  I'm in the central Illinois area, WRB.  

There is a place in Springfield MO called Clear Cast that works on electronics.
