Found it, thanks Damen. R1, 2 & 3 were right there but somehow I completely missed them till I followed the circuit from the flyback up. Zeno you were also right on, sorry I missed what you were trying to explain to me, I only saw R10, 11, 12 at first.
I don't have that cap so will need to order it.
In the meantime, the set has developed another issue. If I turn the brightness down to around half, the video just cuts out. It comes back abruptly if I turn the brightness almost all the way back up, then it can be lowered again, but if I turn the set off at the lower brightness level, there's no video next time I turn it on till I crank the brightness. I'm going to guess it's Q703 again since it is what killed the video the first time, and I installed a used one that I grabbed from a junk board, so maybe I damaged it with all the heat. If it loses video altogether, I will check that one first.
