Hi everybody I have a very starnge problem with my CTP Screen Pt_R 4000
During work maschine said that there is a deviation 5% on some diodes and start calibration after that exposing the plate but when I see the plate is not exposed with corect power (the power is very low).Then I go to service and check the diodes thei rIopd was very high aprox 600ma wich is not possible. The CTP is not calibratinig corectly. When I made manual calibration the Iopd going on its correct values and everything is Okay. Some times I have to make two manual calibration or to restart the maschine.
Do you know what could be the reason? , I have cleaned the calibration sensor and put contact spray on all plugs on the CTP but the problem steel remain.
Thank you in advance .
