A common
problem with early solid-state Gottlieb® pinball machines is damage to
the color filters of the backglass score windows. Often the displays
tubes will rub marks in the fragile color filter, or the filters may be
cloudy, cracked, flaking or scratched. These eyesores can ruin the
otherwise beautiful artwork of these classic games.
|

Backglass
with new filters installed |
The
Pinball Pal score window color filters are transparent, self-adhesive vinyl, cut to the
proper size and ready to apply to your backglass. They are available
in blue and green so there are filters for every Gottlieb pinball machine
that uses numeric displays. Just pick the color that you want when
you place your order.

Good backglasses for
these pinball machines are getting harder and harder to find, and it is a shame
when the appearance of an otherwise nice glass is marred by flaws in the
color filters in front of the displays. Your eye is drawn to the
displays so they become the focal points of the backglass and this makes
even slight flaws much more obvious.
The Problem

Do your score windows
look like this, or worse?

Same score window from
the rear of the backglass
The
color filters used on these Gottlieb pinball machines is a thin layer of
ink that was deposited as part of the artwork silk screening
process. Unfortunately, after decades of use and abuse, this fragile
surface is easily damaged by environmental changes that may leave other
parts of the backglass artwork unaffected. Besides the effect of
age, there is a mechanical weakness in the display printed circuit board
(PCB) which has marred up countless score windows over the years.
The display tube is soldered to the display printed circuit board and the
display is bent to a right angle so that it is parallel to the
backglass. The display tube is supposed to be held flat by some
sticky double-sided tape, but when that tape comes loose (and it will),
the display tube pops up from the PCB and often rubs against the score
window. This rubbing won't hurt these replacement color filters, but
we recommend that you check for loose display tubes on all of your
Gottlieb games, whether you are planning on purchasing our replacement
filters or not - especially if not.

The Solution
Now you
can replace your fragile and deteriorating score window color filters with
these precision-cut and color-matched adhesive filters. Once the old
score window tint has been removed, the new filters are simply peeled off
the backing material and applied to the rear of the backglass.
These
replacement color filters come as a complete set not only for all of the
score displays but for the credit/match and ball-in-play windows as
well. We even provide enough filters for oddball games like Striker,
which has two additional 4-digit displays. Printed installation
instructions are also included.

We recommend that you
replace all of the color filters rather than just the heavily damaged
ones. Even an undamaged filter window will have some degree of fade
and cloudiness and you would probably notice a color mismatch if you mixed
these new color filters with the old original ones.

Installation Instructions
Installation
of these replacement filters is not complicated, but it requires a couple
of delicate, irreversible operations which, if mishandled, could damage
your backglass further. Before you begin, please read through these
instructions to familiarize yourself with the steps involved. Only
you can decide if you are willing to proceed, and we obviously have no way
to control how this product is used, nor can we take responsibility for
any damage that may occur. This concludes the CYA disclaimer.
Basically,
you just scrape off the old tint and stick on the new ones. Here are
some pointers:
-
Do not
let water or any liquids get anywhere near the ink side of your
backglass. Ever. Most liquids (including water) will dissolve
the tint color, but it is too risky for us to recommend using liquids on
the backglass inks. It is too easy to unintentionally (and
permanently) remove artwork that should not be touched.
-
Use a
new, sharp blade to remove the old tint. You can use a single-edge
razor blade, or an X-Acto type knife with an appropriate blade.
The common #11 blade does not position the cutting surface at a good
angle for this operation, so you will have a much easier job using a
chisel-type blade. The best tool we can recommend would be a #2 X-Acto
handle with a #18 chisel blade. The #2 handle is larger and
heavier and the #18 blade is just a half inch wide - a good size for the
smaller credit/match windows. Hobby shops and the tool department
of large hardware stores should have these, or there are many on-line
sources for small tools (such as http://www.towerhobbies.com).
-
Keep
the work area clean. Any dirt that gets trapped in between the
filters and the glass will be there forever. Try not to touch the
adhesive side of the filters, especially if your fingers are
dirty. The fingerprints typically won't show, but all of the dirt
that gets pulled off your fingers will.
-
To
avoid light leakage, the replacement filters are slightly larger than
the score windows, just as the original screening was done oversize. The
new filters have a strong, permanent adhesive that will last for many
years. Once the filter is attached to any of the surrounding
backglass ink, you must not pull off the filter because the backglass
ink will likely come off with it. Because the filters are slightly
oversize, there is some latitude when you place them down, but once you
start putting one down, there's no backing up. If this is too
scary for you, there is a compromise: Just apply the filters to the
front of the backglass. It won't look quite as good that way, but
it is easier to do.
Here are
step-by step installation instructions:
-
Verify
that you have the correct filter set for your game. This
includes checking the color (blue or green) and also checking the
size. We have made every effort to insure that the filters are
precisely cut to the proper size, and we have surveyed the backglass
window size of many (but not all) of the 41 particular games that are
supported. Plus there is always the possibility that there has
been some differences across production runs, or other unknown
variables lost in the game's history. These game were made about
the year 10 B.C. (Before CAD), so all of the original artwork was done
by hand. Because of this, every window is slightly
different. So although all of the new filters are cut to the
same size exactly, don't assume the backglass is the same To check the size, simply
place the filter sheet against the front of the existing score windows
with some sort of light source showing from behind (the score displays
themselves might work fine). You just want to verify that the
new filters are at least as high and wide as the existing filter
window. If any of them are not, do not proceed with the
installation and notify us immediately. We need your feedback so
that we can make any fine adjustments, if necessary, for you as well
as future users.

Removing old tint with X-Acto
chisel blade
-
Scrape
away the old tint with fresh, sharp blades. Follow along the
black key line that outlines the score window rectangle.
Obviously, you want to work very slowly and carefully. One
technique is to first scrape off the middle portion of the window with
fairly quick strokes, but keeping well away from the edges. Then
follow up with more careful strokes to clear away the old tint just up
to the black outline. It also helps if you have a non-glaring
light source on the other side of the glass, which will make the
tinted part stand out more readily. The neater that you make the
window, the better it will look up close. However, minor nicks
in the black outline or small amounts of old tint around the edges
will be just barely noticeable. If you do accidentally take off a
chunk of the outline, you can touch up the line now or after the new
filter has been installed. It may look a lot more ragged when
your nose is up against the glass while you're scraping than it will
once it's all back together and lit up normally.

-
Scrape
the old tint from the two smaller display windows. The
Credit/Match window and Ball-in-Play windows are each two-digit
displays which are each one half of a single four-digit display
glass. There is a fairly fine line dividing the two halves of
the display, so you should take additional care when removing the old
tint from these smaller windows.

Credit/Match
display windows after removal of old tint
-
Make
sure that there is no trace of the old tint in the central part of the
windows. That's where it matters most since it's the score
display that is what will be showing through the window. If
you're careful, you can use a swab or cotton ball very slightly
moistened with glass cleaner or alcohol and clean just the central
portion of the score windows. Do not get anything even moist near the edges
of the score window.
-
Remove
the old tint from all of the windows before you apply the new
filters. Once all of the old tint has been removed, clean up the
places that the fine dust has accumulated, such as your blades and
handles, the bottom edge of the backbox frame, and (most of all) your
fingers.

Applying a score
window filter
-
Now
you simply apply the adhesive filters to the back of each display
window. If this is your first attempt, you should start with the
Player 3 or Player 4 window. that way, you'll be an expert by
the time you get to the most noticed window: Player 1. Carefully
remove the new filter from the backing paper and position it close to
the backglass window. Be sure not to slip and touch the adhesive
to any areas of backglass ink or you may mess up not only your filter
but your backglass. As you move the adhesive filter closer to
the window, make sure that there is some overlap on all sides - top
and bottom, left and right. As long as there is some overlap you
are fine. From the back, it doesn't matter if the new filter is
slightly cocked or off-center, as long as there are no open gaps along
any sides. Just move slowly closer and closer until one side or
the other makes contact. Then, you are committed. Gently
run your finger horizontally across the center of the window.
You want to work out any possible air bubbles, so start at the middle
and gently work the filter down completely. You do not need to
exert a lot of pressure. After the filter is completely
down, wrap your finger in a lint-free cloth and again work the filter
down, using a variety of strokes - circles, left/right, up and
down. The filter is now a permanent part of the backglass.

Repeat
this process for all of the other score windows, including the smaller
Credit/Match window. In this case, the filter will cover the
fine line of artwork that divides the display in half. Since
this artwork is already opaque, it makes no difference that the filter
is behind it, and we have just saved you a little time by doing the
two windows in one step.

This
completes the installation. Close everything up and fire up the
game. If you had damaged any of the window outlines during the
tint removal process, you may see some light leakage around the
window, and possibly around the new tint window as well. If you
find this objectionable, you may wish to touch up the back of the
backglass with an opaque paint such as Testor's enamel hobby
paint. Unless you are confident that you can do more good than
harm by touching up the artwork, you are much better off leaving it
as-is.
-
If
your backglass hasn't yet been sealed, this would be an excellent time
to do it. The most well-known sealer is Krylon's Triple-Thick
Crystal Clear Glaze, which is widely available. Coating the back
of your backglass will help prevent further flaking of the backglass
ink, and will serve to lock down any loose or hanging flakes that are
still attached somewhere. To seal the backglass, you will have
to remove it from the backbox frame (just unscrew the nylon wedges
around the edges). Then the backglass should be laid face down
in a dust-free space. There is no need to seal over the display
windows, and it is better if you don't. The light from the display digits will
be slightly distorted by the layer of Triple Thick - not seriously,
but it is noticeable. The good thing is that now that you have
these fresh, new filters installed, you don't have to worry about
damaging them when you mask them off. You can use regular
low-tack masking tape or you can cut heavy paper that is the same size
as the windows and hold them in position over the windows with small
weights such as coins. Remove the masking material as soon as
you have finished spraying the sealer, wait for it to thoroughly dry
and it's ready to go back in the machine.

We hope
that you are pleased with the results of your work. This is hardly a
"plug and play" kind of restoration task, so pat yourself on the
back for taking it on. Along with the risk of really screwing things
up, is the even greater satisfaction from a job well done. If you have
pictures of any of your projects that have utilized Pinball Pal products, we
would like to feature them on our Gallery Page.
Just get in touch with us and let
us know what you've got for the gallery.
