specifically EV900-7000595
The last day it was working it was randomly clicking a lot and the
screen would jump when it did it. Now it wont power up but clicks
(buzzes) quickly making a racheting sound if I try.

As you can tell, I haven't pulled it apart yet or know the correct CRT
jargon but I'm good with a multimeter and soldering iron so I'm not
afraid to dig in.
People mention the fbt a lot with this model as a common failure spot.

Somebody please tell me what to check.
Thanks
