Hello again. I used a DVD player, and ran it through my VCR to get these signals. Sorry about the extra trace in the pictures. I couldn't figure out how to make it disappear. I appreciate all the help so far, and could use some feedback as to where to go from here.
Photos #1 and 2: Output of first sync amplifier. About 60 volts. Probe X10, Scope X2 scale.
Photo #3: Input to sync separator. About 25 volts, which would be low. Should be 35 volts. Probe X1, Scope X5 scale.
Photo #4: Output of sync separator. About 80 volts. Probe X10, Scope X5.
