Chris:
Do you have audio? If not you need to start back from the high voltage. Also it is possible that those .1 caps are bad. In what circuit are they? Don't overlook the obvious, tubes could be bad. Check the horizontal output and the 1B3. Assuming all that's good a quick check to see if the horizontal section and flyback transformer are working is to take the top cap off the 1B3 and wrap the leads of a small neon bulb around the wire. Turn on the set and if the bulb glows everything up to the 1B3 is working and the problem is between that and the CRT. I think you can still get neon bulbs at Radio Shack.
