Re: Tempest Color Vectors

Been working on a Tempest for a friend. At first there was no video but the game played fine.
I found a broken trace between K5 and K3 as someone long ago attempted to replace a 2114
and in the process, burnt a trace.
So I got video back, however have come across the most peculiar problem. At first I thought it
was a simple issue of the color transistors, so I replaced Q2-4. Nothing changed. I also replaced Q8-10.
I am completely missing Red, Green and Yellow. Has anyone else come across this problem?

Bad color vectors:

What it should look like:

Thanks for any help.
