[Test-Equipment] Does my 141T have a terminal illness?

[jeremy-ca]

It was working fine and then the trace came and went once in awhile. 
Excellent intensity and focus.

Then it just went blank. I can turn up the intensity and get a backround 
glow. When I go over to manual I get a single dot on the screen.

Is this the dreaded CRT death or have I got a sweep problem?

Dont even have a manual, its been working fine for 10 years.
