If L8 is shorted and video is getting through, should still work.

I would agree that the first thing is to check the horizontal oscillator frequency.

P.S. Wow - talk about corner cutting - only 2 video IF's and both sound and sync taken off the video output AFTER the contrast control. Yet, they spent money on a noise canceller stage. Must have had an extra tube section they didn't know what to do with.
