    output pcb,Drive voltage pcb,Data output pcb,MLVA filter wheel,MLVA lamp.But they are all ok.I check light flow from the
    MLVA face tube when Head cleaning.But no light outputting from the MLVA Head.Light is present on intigeter section.Light also

        Try to replace the LVDS-cable between Image Processing PCB and Data Output PCB.

          Had blank photo, when color wheel sensor didn't work. No any errors. Check output pulses with oscilloscope.
