RE: TECH: Battlezone 15" monitor question (G05-805)

Dave,
Diagnosis is pretty easy, repair is pretty easy, but the part is getting
harder to find. The symptom is called (at least on this list) "blooming,"
and it seems always to be caused by a failing HV diode. It can be replaced
with an sk7333, an sk7330, the original Varo h1812, an NTE527A, none of
which are currently in production. The 7330 and the H1812 are drop-in
replacements. Rodger Boots posted less than a month ago that he had 2 H1812s
available; he might still have one.

Subject: VECTOR: TECH: Battlezone 15" monitor question (G05-805)

I finished repairing both my Battlezone boardsets, but have a problem with
the monitor with both boards. When you turn the game on cold, everything is
fine. As the game warms up, the monitor picture expands until the radar/high
scores off the screen. I'm not sure if it expands side to side, but I
haven't really noticed it doing that.
 
Haven't worked on Vector monitors before, but I was thinking a cap kit...
until I looked and saw there were very few caps. Can anyone point me to
something to try? Is there a common fix for this problem? It's the last
repair I have to do to this machine and would love to get it out of the way
soon.
 
Thanks,
-Commander Dave
