Ok, so I've spent some time trying to understand where the problem might be (on top of my very limited knowledge) and here what I find.
When I start the scope, for a fraction of a second I see a trace (more frequent if I have the beam finder pushed). Does this mean the CRT is still working ?
Once the scope is working, if I push the beam finder I see nothing.
I was then trying to see if there where some signal in the defl plates and I found that I do have on both horizontal and vertical.

I see also that on the ASTIG I do have some signal as well, but still no single sign of trace... to be honest, I do have much knowledge to understand if even I'm going in the right direction.. should I be seeing anything ? or this can simply mean the problem is someplace else ?
PS: according to the service manual, the horizontal signal should be between +25v and +63v from the wave forms but I no longer have an oscilloscope to test it ... if so, getting 7.3v only on point 9 means something is wrong already ??
Thank in advance for the inputs.
