Does anyone know what the red indicator light signifies when it is blinking. Ours is usually on steady. The light is hard to see in this pic but it is just below the silver screw head bottom right of the selector switch.
My assumption would be that it is an indicator light verifying that there is DC to the panel. If it used to be solid, and now 'flickers' it may be a bad connection to the bulb or a dying bulb.
