Those are usually easy to find, and are almost always a leaky electrolytic. Or a leaky selenium could cause it, but more likely, a leaky selenium would have shorted out or passed enough AC to overheat the electrolytics and blow.
If it's causing the vertical to flip, I'd look at the main B+ supply, and see if it has AC riding on it. 99% sure you have a bad filter. OR, the set is getting a hot loop through the antenna line... NOTE: Hot chassis; use an isolation transformer when poking for AC in the B+. You might read AC falsely if the scope or VTVM is plugged in opposite polarity to the TV, as well as posing the obvious risk of shock or damage. Charles
