You cant test those two diodes with a multimeter. You need to use something that applys in excess of 200volts like an eye type tube tester in the leakage test mode.
The smaller of the two diodes is the boost diode. Check with you meter to verify you have boost voltage coming out of it.
The long one is focus.
BUT, those solid state tubes can cause all kinds of issues like super high voltage.

Until I get some more time for troubleshootin', can you tell me (us) more about these solid-state tubes? I've never seen something like this, and it seems especially odd since the LAST thing to become solid-state was typically the HV rectifier.
Was this some kind of aftermarket part? Who made them? Why?
As for measuring voltage after the boost diode, that requires the cage to be open... Is that allowed by the TV safety gods? I'd hate to have "always seeking better gray scale" on my tombstone.
