To you too!
Q402 looks a bit weird. Q402, Q404, and the Video IC have all been replaced with new parts to check for any difference and none was found.
Also, the waveform on the other side of T401 looks correct. The rest of the set is not connected to Q402,404 besides the 134VDC supply, but even then only through a number of other components
All the parts in that whole section have been removed and checked for values with an LCR meter.
