I have a question for for you guys. I have a Lowrance LCX15 MT. The depth number is flashing and the screen display speeds up and then slows down. I checked my connections, there all good. It is connected to a separate battery so interference isn't an issue. Voltage is at 11.8. and the battery is fully charged. I didn't have the problem last year and don't have a clue what started it this year. I'm going to clean and check the cable connections at the back of the unit itself. Can't think of anything else to check. The tranducer (transom mount) seems fine as well. Anyone with any ideas? Appreciate the input!
