Interesting. I wouldn't think that the G2 would cause some kind of strobing red situation like that.
I have had a bad flyback pot before, and that did actually cause flakey flashing, but it wasn't set wrong, it was loose inside and the slug would pop in and out of the pot and cause wildly erratic brightness levels. I had to replace it.
The fact that you got red strobing probably means your color background (also called bias) is set wrong. If the G2 was to blame, it's bringing up all colors equally, and it shouldn't have looked red like that. It's needs to be balanced.
