Question about testing flyback

[Aperna1985]

Okay I went through the set again, I installed the new cap on the focus control, found one defective new cap in the damper circuit. I also found someone had replaced the socket on the 1V2 and they did a terrible job of it, the wires were making intermittent in contact. So I redid that whole section. I now have almost 15,000 volts the picture is plenty bright. But I have it changed the main filter caps yet. It's actually the only old capacitors left in the set at this point other than discs. The tuner isn't getting high voltage at the moment. So I tried to inject a signal in on the video amp. This TV has a video input which is pretty cool it connects right to the grid of the video amp. As I reach down to connect my pattern generator it actually Drew an ark. So I went to go test the voltage on that tube. What was interesting is I had no voltage on pin one pin 2 or pin 3 I had 272 on pin 6 and 50 volts on pin 7 and no voltage on Pin 8. Also will the image not lock if you don't have a video signal? I'm getting patterns on the screen but I can't seem to get it to lock and just become like a blank picture.
