We have a 1260 FLD G7121A This detector is showing an error "Emission motor did not find position (position mode). When we look in the service manual it appears as part of the assembly and the reference is G7121-60004. However, when we are looking at the Agilent page it does not It gives us information. The reference of that part was changed? Is there any test that I can do so that this motor finds its position again or should it be replaced definitively? If so, they confirm the parts that I should request. P.D: I was FSE with an Agilent ASP, for more than 10 years and now I work in the Metrology area of a pharmaceutical company, initially attending to the problems with the equipment.
