There will be no waveform at the collector lead. Disconnecting the HOT will stop the horizontal sweep and high voltage pulses from being generated. They are the most likely source that drives the ringing since they are the largest currents and voltages in the set, but may not have the ringing themselves anyway - they may only be exciting the ringing in related circuits. With the HOT disconnected, you can look for the ringing elsewhere, but it may no longer exist.
Edit: have you tried experimenting with auxiliary grounding wires just to see if the on-screen pattern changes? If you see a change, it will help to identify hot spots for the ringing.
