Hello. I am looking for clues as to what is the cause for an Ursa Diamond CRT failure:after 3 weeks of being powered down it turned on ok, all boards on, all fans on, but EHT lamp allways intermitent and no test signals.Best regards to all:

You might want to check the red LED lights on the 2111 board (lower right rack first board on the left) and if one of the two staus on you should look at the small PSU inside the deflection amp as it is likely in need of replacement or adjustment.
