Hello, dear group.
I´m servicing to a C-Arm Pulsera from Philips. When making fluorospopy get blurred images. I´ve already checked voltages on image intensifier power supply. Voltage measured at test point Vg2 is +3.15v, but according to technical specification on service manual, it should be +0.8v. Those grid voltage values make me think that II power supply is damaged, but I´m not sure about that. Could anybody help me to make a better diagnostic? Your assistance will be unvaluable.
Thanks before hand.
Regards
adjust g1 voltage to balance edge focus to center focus, g2 is the main focus adjustment, g3 is the size adjustment. They all interact a little, so adjusting one a lot may require a minor tweak of the other two
Hello!
Have you tried the other zooms, too ?
Same issue ? Is it completely unsharp or only little bit ?
Usually the focus can be adjusted at II power supply, but only by smaller deviations
You can also remove the camera from II and hold it in the room ….if room is sharp seenable you can be sure that problem is not from camera side -
