Purchased a new LCX 28C HD last fall. Used it once before I had to store my boat for the winter. Got back out on the water last month, and now the sonar display works intermittently. Works for a few seconds, then flashes for a few seconds. Then works again, then flashes again. Voltage is good, wiring is good.

I am stumped, has anyone else had this happen to them, and how did you fix the problem. Called Lowrance tech support, not much help there.

Thank you in advance for any help you can lend.
