Flyback lines? Is the picture all white with no brightness control with faint horizontal faint lines? If this is what you are saying, the screen voltage could be bad, and if thats the case, the picture tube or the flyback itself could be bad. You could also have a bad connection on the crt socket

crt beam current too high causing shutdown as you know. Check cathode voltage of each cathode, normal levels depend on picture is around 130-150V. Missing 200V to crt board. Screen voltage problem normal 300-500V. Flyback or bad crt. ABL circuit problem. Jungle IC.

I could still make out 68 over 2kv on the burnt capacitor. Replaced with a 680 pf 2kv that I bought at a local TV repair shop. works great.
