I replaced C307, a 1UF/63V orange drop capacitor to fix the problem. The
question is what is wrong with the capacitor? I used a .47UF/63V orange
drop cap to fix it since I did not have a 1UF and the picture is perfect
so the value is not critical. The original cap reads .9XX UF, about 5.8
ESR ohms, infinity ohms leakage. In circuit there is -13 VDC on one lead
and a normal 55 VP-P vertical output signal on the other lead with very
little DC offset. The .47UF that I used to fix it reads .46X UF, about
3.0 ESR ohms, Infinity ohms leakage. So what the heck is wrong with the
original 1UF cap?
