1978 Sylvania console problems

[jg6364]

I have had this set for several years. About a year ago the HV tripler was replaced. Just recently I was trying to play it and the picture is scrambled. The audio is great and if you turn the fine tuning ring the picture will go completely black just when you think it is going to clear up. I'm attaching several pictures and a video What should I be looking for? I pulled a lot of the transistors and cleaned the connections just in case that was the problem but no luck.
