first of all thanks to the group members for providing great info on how to repair/troubleshoot the 2445A power supply - all working fine now.
So scope is working fine except option 5 (Video Waveform Measurement System).
When I got the 2445A the option board was not connected so I'm not sure how to reconnect and even if all the cables are there.
Added a photo is the Photos section - is it only cables A/B/C ?
Your help is appreciated.
