SUBJECT
games that use the Wells Gardner model
19K 7901 monitor.
PROBLEM
Games comes on ok, but after period of time
the picture goes blank. Logic and power are
present, but no filament voltage can be seen
in the neck of the CRT.
SYMPTOMS
This can be a very nagging and annoying
problem because often times the game will
seem to work fme, then when moved on
location, or left on, the monitor will go out. I
first suspected that the over-voltage protec-
tion had kicked in due to high line voltage.
CAUSE
However, this is not the case. I removed the
monitor chassis and gave it a physical exam
and noticed that on Tl, the high voltage
transformer, Pin 1 had broken loose from the
solder pad and was making an intermittent
contact with pad.

SOLUTION
PROBLEM
I re-established a good solder connection
with this pad, and with some of the other
pads, which seemed to be breaking loose
and I have had no problems since. This
problem has happened to 3 of the U /R After
Burners, and 2 of the Top Speed monitors,
possibly because of the high amount of
vibration and current demands put on these
pads by these games.
