Howie usual for the VDE caps to burn up or explode on a 240V mains but seldom on 120V.
No overheating as the event is rapid and the caps are inside the EMI / IEC modules.
Also check the LV PSU board for blowing rectifiers and lyrics as well as tantalum caps.
See th¨¦ EEV blog 75 pages on 2465B teardown.
Bon chance
