SYMPTOM
A Terminator 2 video game with
a 25" Wells Gardner color moni-
tor that suddenly went "greenish
white".
THE PLAGUE
then the monitor is at fault. From
there, you then start to trouble-
shoot the bad unit (monitor, CPU
or wiring harness).
The background got very light
with a green tinge. In order to get
the background neutral again the
green screen must be turned all
the way down. The other drive
controls had to be remixed to get
some sort of balance.

We are no longer at

PROBLEM
Now, the background is black,
but the color isn't right. It looks
all blue and red and turning up
the green drive screws the picture
up. Obviously, something failed.
Any clues? Where do you start?

Thanks to Todd Erickson for his
valuable article about the new
Williams flipper Mega-links
(S*TI Apr93, Dec93).
Broken links have been an abso-
lute plague for pin mechanics and
the new Mega-links should cor-
rect most of the problems. Cheers
to Williams for offering an up-
grade for older games at a rea-
sonable price. It's nice to know
that they are concerned about
past sales.
PRECAUTION
After installing the kit, care
should
be given to adjusting the

or binding will result.

SOLUTION
First thing to be done is to use the
built-in monitor test patterns
(very nice to have, thanks Will-
iams!). Check the various color
screens and color bars.

the problem is, simply switch the
color wires around at the moni-

moves with the wire, the board is
