    Hope someone out there has any tips on this. The unit came in
    with absolutely no vertical sweep. The horizontal line has also shrunk
    in from each side by two inches. There is audio. R14509, 300-ohm, in
    the 13v+ source, runs very hot and is discolored. I replaced CR14704
    in the 13v+ source and U14501 vertical output chip. No improvement at
    all. Any help will be greatly appreciated!

    Check for high ESR caps in the vertical def amp, and also in the power
    supply to start with. Defective caps are common in many of these sets.
