Bonjour WORGH, have used,and fixed 2465/7/B since 1990s.
I am very wary of any older SN, or no suffex 2465 or A.
Any vendor with "government" is also a flag.
Repair can be PS, or HV, and control board,A5 CAL,RAM, SMD,lytic corrosion
CRT damage is rare, unless it,was dropped or mispackaed in shipment
The very,severe defects appears more,than a PS, or just bad HV.
Even for very experienced 2465 veterans, with best CAL equipment, it can take hours, days weeks...
One,dog I have had on the bench since 2018!
You should get the full service manual for the model and serial, follow the excellent flow charts and check each board and subassembly in sequence
Alternatively just write it off as,a parts,donor, and look out for a,100% working 2465B.
Bon courage
