I do know how to use an O-scope, but I am new to monitors. The one I have at work is typically used for our microwave radio system.
I have tested all of the diodes in the circuit and they appear to be good, but I really need to lift one end and test them that way. R219 seems to be good. I will test T113-T118 as you suggested and see how those look.
I have recapped the monitor and everything looks good there.
If the voltage at TP6 is high, does that indicate a short somewhere in the deflection circuit?
