    I am not familiar with the GP335, but does it have a scan lamp sensor? ccd? If the lamp is coming on and it codes out anyway there must be a way it reads the lamp. Lamp regulator?
    Is the glass half full or half empty? I say neither. The glass is obviously full, full of potential. The potential to hold more water or the potential to quench a thirst. Life is all about how you see it.

        we do face this problem very often, is due to composite power supply, normally is caused by dry joint of the pcb ass'y.
