I have lenco trim tabs with the led control panel that is suppose to light up along the sides of the up and down buttons to show what angle the trim tabs are at. Well my leds are not working. The tabs work fine and the up and down buttons are working great, as a matter of fact I just replaced the control pad because the old one was doing the same thing, and I thought it was a bad control pad. Anyone have the same issue? or have an idea what it could be?
