Equipment: bv pulsera c arm philips

Hello, dear members of forum.

I have a Philips Pulsera Mobile C-arm system. Recently, I have been facing up some error codes. It is M326 and M050. After checking it, I found the fan in ESU unit stuck. It was already replaced, but equipment is not working yet.

The whole battery set was recently replaced, but after a 24-hours charging cicle, battery voltage is just +339 Vdc. I know that it should be +360 Vdc. Could someone help me to solve out this issue? I´ll really appreciate any help. Thanks in advance.

Regards!

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, it does not change eventhoug I change format to 17 cm or 23 cm. 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
