WhenI check LCD stability in SU mode (withTEC password) it does not show stability at all and values goes to extreme to 32768. it happens to all color randomly. 1) Changed step Motor 2) Cleaned color filters 3) changed Lamp, 4) changed PCBoard, next to filters.

MALACAL Posted December 26, 2010 Report Share Posted December 26, 2010 the photo diode is located in the center of the plane of exposure, remove the two screws and separate with some bands to remove the plastic piece to which the sensor is fixed Quote Link to comment Share on other sites More sharing options...

MALACAL Posted December 27, 2010 Report Share Posted December 27, 2010 check if the voltage of the lamp power supply is stable check the engine that drives the filters, check the zero position replace the photo diode Quote Link to comment Share on other sites More sharing options...
