Can you get to the back of the display unit? That is where you will find the wire. Was very simple in my case.
I had this happen with the flashing lights but it was the inverter/converter remote display doing it. Like computerguy, the remote was connected with a telephone type connection. I pulled the display, unplugged it, and plugged it back in and all has since been good.
Look forward to what finally corrects your problem.
