Beseler colourhead for 45 and CB7 series question

[MarekWarunkiewicz]

Hello all!

I’ve searched the net looking for a repair manual for these.

Does anyone have one or can provide repair guidance?I have two that work, one has a sticky dial. I also have three that I cannot get to work. Want to see if I can repair the three that do not work and sell or should I just sell them for parts?

Thanks!

There are many version of color head for the 45 and CB7. I had the dichro DG for the CB7 and the 45 computerized color head for the 45. The computerized color head I had broke and it's electronic was over my head. The Dichro DG is quite simple in term of electrical.

Yes, specifics on the particular head you have are needed. There were many different ones over the years. There are numerous threads about repairs if you can be exact. Fortunately I got a tip from the seller of one of the electronic heads that has never failed me so far: open it and unplug and plug back in the 3 circuit boards a couple of times. I keep waiting for a more catastrophic failure but his has brought it back to functionality every time.
