SYMPTOM
SUBJECT
SYMPTOM
We noticed when Phantom came
off location that the speech over-
powered the regular music.
Pinball playfield coating mainte-
nance. Starting with Star Trek
pinball, Data East is providing a
new"Stealth"Top Coating on the
playfield surface. This new coat-
ing has been proven very effective
in it's several years on test, but
for maximum life, a regular
cleaning maintenance should be
performed.
No response from STAR-ft-TECH
Journal's BBS service.
SOLUTION
Al though the sound boards look
almost alike, if you use a sound
board from an earlier Data East
game (Secret Service, Playboy,
etc.), 2 resistors located at Rl 7
and R18 must be changed to 43K,
in order to balance out the sound.
CAUSE
Apparently, our sound boards
were switched at some point.
Data East told me to check those
resistors, and then we even spot-
ted it in the manual prints too.
Now all sounds are in perfect bal-
ance with the speech.
Address Changes
Please use your account
number when updating
your subscription
information.
Your account number is a
five digit number found
on the top line - left side of
your address label, which
is affixed to your journal.
MAINTENANCE
We recommend Novus Plastic
Polish #2 for the best perfor-
mance. This polish is both a
cleaner and protectant and
should be used on a weekly or
bi weekly basis to insure the long
life of the playfield.
In addition, this same cleaner
may be used on plastic ramps in
the game, because it does not con-
tain petroleum byproducts. It
will not discolor or "fog up" the
plastics as other cleaners might.
CAUSE
A rogue summer thunderstorm
unleashed a direct lighning hit
upon the phone line serving the
BBS. All hardware was fried.
SOLUTION
S -ftT J is now looking for a loaner
modem and computer (IBM or
compatible) to quickly get back
online. All software, incidently,
was recently backed up and is
safe and valid.
Hopefully, the system will be op-
erational very soon. Any changes
will be announced in the next
issue.

Intermittently the Hook game
may perform erratically, occa-
sionally going into "Slam Tilt" or
kicking some solenoids for no ap-
parent reason.

CAUSE
~ An
intermittently grounded
• switch strobe line. (Typically the
green wire with the yellow trace
on the left Drop Target bank is
pinched against the playfield
support bracket.)
SOLUTION
Check the wiring on the left Drop
Target bank to make sure that
none of the wires can be pen-
etrated by the playfield support
bracket on the left side of the
cabinet.
PROCEDURE
If the wires look like they might
get caught when the playfield is
in its normal position, dress the
wires away from the edge of the
playfield and secure them to the
harness with electrical tape or a
tie wrap. This should prevent
them from drifting back where
~they might get caught between
the playfield and its supporting
bracket.
Any questions contact the Data
East Service Dept 1-800-Kickers.

EQUIPMENT
All bill acceptors and games em-
ploying opto switches.
PROBLEM
It is often difficult to quickly de-
termine if the problem with an
opto switch is in the LED or the
transistor portion of the unit.
SOLUTION
MURPHY'S

corruption
is always reported
in the past tense.
Purchase a Infrared Detector
Probe. I found an inexpensive
probe available from MCM Elec-
tronics that measures 4. 75 "x. 75"
for $6.95, part #72-003. This
probe is simply a piece of plastic
that glows pale orange when in-
frared is present. The size of this
probe works well in bill acceptors
and pin game opto units where
accessibility can be a problem.
PROBE USE
You can quickly determine which
half of the opto assembly is the
problem by simply exposing the
probe to the LED.
NOTE

It is easier to see the probe glow
under subdued light conditions.
Also, test both halves of the opto
assembly if you are not sure
which half is the LED portion.
