You're right, old_tv_nut, I did do that, didn't I. I guess I'm looking for a quick solution to a problem that requires deliberate troubleshooting. Sorry about that. It's not easy trying to help someone from a distance, and I appreciate the effort. Now to answer your question. The picture control does seem to work correctly. It's the brightness that had been working, but stopped. The syncing problems have been consistently present.
Also, I did replace and wiggle the tubes, Kramden66. That doesn't have any effect.
Thanks for the troubleshooting advice, Electronic M. The controls do affect the direction of the vertical and horizontal lines. Can you tell me if I would need an oscilloscope to check the video levels, or can it be done using a multimeter? I've got one, but it's been a while since I've used it.
