We have a Lowrance HDS7 on the bench today with a defective sonar.
This one was giving the customer quite a bit of trouble, even making networked sonar unusable on other devices.
After a couple burnt up components we were able to successfully diagnose and repair the issue!

So impressed! I have same unit and sonar stopped working last time I used it. I will do a little more trouble shooting and if I can't figure it out I'm sending it your way! Thank you!

I purchased a brand new Elite 12 Ti2 this past November. When I installed it and went through setup, it exhibited the SAME exact sonar issues as the HDS7 you repaired in this video, and we're talking a brand-new, never-used unit. My guess is it had a similar issue with the actual sonar circuitry...shorted components, who knows. Was very disappointed considering it was a new unit (obviously being under warranty and brand new, it had to be replaced rather than repaired). I wasted hours troubleshooting the unit (and went through a transducer replacement) thinking I was doing something wrong, considering that everything else worked fine (GPS, mapping, etc. worked). Lowrance must be doing some cost-cutting with the electronic components.

Awesome job ! My depth and speed are in and out using gen 1 and a 2 with the structure mod and transducer even plugged a 3 in 1 into them and it's the same scenario

Classic symptom of a failed sonar preprocessor, unfortunately

Hds 9 doing the exact same. Blew a fuse 4 weeks ago. Replaced and graph wouldnt work. I get a running static screen and no depth reading. What kind of eta is your turnaround?
