Why do I have dashes on my HOOK display | Lowrance

The power and transducer connectors for the HOOK family have a set of friction rings, which keep the cable properly seated in the back of the display. Any time there is a lack of sonar or temp data, or the power is flickering this is the first place you should check.

Do not use dielectric grease on your connector, as this will reduce the friction, and the connector will slip out.
