I have one of these fish finders……came with a boat purchase. Every so often the screen goes blank. I’ve tried the reset procedure to reset screen but this hasn’t fixed it.
Does anyone know if it is repairable?

Is there power to the unit when it goes blank?

OK, thought it might have been a loose fuse. I've had that problem before.

The pins in the power socket and transducer can get gunked up and not make a good contact that bouncing of the hull produces a temporary disconnect. I would try a spray with electrical connection cleaner.
