Re: SCX-4200

Hey guys,
I have a problem with SCX-4200. Gives white (barely visible imprint). Second cartirdges - the same. In the service manual I have find directed that might be grounding OPC drum. Zener diodes on the HV board. Has anyone changed and if someone could explain to me and where it is exactly on the HV board? And if you have Part no.?
Thank you in advance for any help

Another sad one...
