In the convergence menu Green does not appear only the standard RED on Green and Blue on Green.
On the 801s set with COG board installed green appeared on the convergence menu.
I do have a couple of these boards and I have changed them but there does not seem to be any adjustment for it. Is this right or I am I looking in the wrong place for the adjustment.
I did try a different control board with later firmware and it simply said COG present but did not offer any way to adjust it that I could see.

There is jumper on the COG board that may need to be moved.
You should see "green only" in the convergence menu

Exactly the markings are really not clear. It has been a while but the jumper has two positions something like "7 series projector" and all other projectors. On both the 808 and 120x series you need it on the "7 series projector" side. It is totally counter intuitive. You won't damage anything by trying the other side. If you have the jumper in the wrong place you won't see the COG option. I have installed several COG boards in my time and they were all like this.

Change the jumper to the other position. Guaranteed that's it. I've never had a bad COG board, but have installed a few 'I swear the jumper is in the right place', and it wasn't. You won't blow anything up if it's in the wrong position.
Got your PM, but I won't have an 808 to test the convergence drivers on the bench for a couple of days.

Changed the jumper and it now works. So thanks. That jumper is confusing as it just seems backwards.
