Did you re-cap this set?
I went through and replaced all transistors in blanking, video output, amps, etc. There was no change and I put all the originals back and kept the new for backups. I replaced the blanking diode and the resistors that work with it, but that didn't help. That leaves the three diodes around the horizontal output and I'll be ordering them tomorrow.
