if the whole display rocks up and down,bottom ,fish and jig with a squealing noise its just a matter of time before the motor takes a dump.that's what all three of my marcums did..but if it clears up when in a warm environment maybe your battery is getting weak due to cold and recovers a bit when warmer..those vx1pros,lx3tc and lx5 motors go out frequently thats probably why marcum stopped making that line up and went brushless.jmo
