PROBLEM
PROBLEM
SYMPTOM
Tired of finding and repairing
broken wires on the opto boards
time and time again?
Trouble with a Electrohome
GO7-CBO: The beam is at full
strength.
SOLUTION
SYMPTOMS
Try silicone glue to hold the wires
in place. They'll last l00x longer!
Changed transistors X303 and
X304, and all the capacitors that
are normally associated with this
circuit. The blanking pulse is
present.
An MTC9000 33" monitor was
brought in and on power-up, it
would shut down immediately. If
the monitor was turned off and
on in two second intervals, it
would fire up. When completely
turned off, the same result again,
it shuts down immediately.

when out of the
office -
The only difference between this
chassis and a working chassis is
that the 12v on the base of X303
drops to about 5 volts and in so
doing, cuts X303 off to the point
that it cannot control the beam.
SOLUTION
Check C107. It's the l0mfd @
250vdc capacitor on the neck
board. It causes symptoms simi-
lar to those described above.
SOLUTION
I found C35 to measure only
.89mfd when actually it was sup-
posed to be 22mf d @ 25v. After
this capacitor was changed, the
monitor fired up every time.
NOTE
This same symptom can also be
caused by C34 (22mfd @ 160v)
being off value and R94 burning
open. The reason for the R94 (3.9
ohm) resistor opening is usually
because too much current is
drawn. Check I Cl (TDA 1670) or
C57 shorting out.
this keeps
questions from
subordinates and
superiors at a
minimum.

ARCADE PROJECT
TECHNOLOGY
The US Amusement and Music
Operators Association (AMOA)
has announced participation in a
project to create a nationwide
interactive, digital multimedia
network. Beginning with a two-
state pilot, the association hopes
the network will eventually link
together 100,000 game terminals
throughout North America
within 3 - 5 years.
Konami Co. Ltd. has announced
that they have begun work on a
line of commercial game prod-
ucts that will employ the com-
puter graphics technology of
Sony Computer Entertainment
(SCE). The Sony technology had
been developed for use in con-
sumer video games. Konami
plans to release their first prod-
ucts next year.
The partners in the project are
National Amusement Network
Inc. (NANI) and EDS Corp., a
Texas-based information tech-
nologies applications firm. NANI
is jointly owned by the AMOA
and a Canadian company TV
Phone, Inc.
Konami has decided that the
quality of SCE's technology, par-
ticularly its computer graphics
and VR imaging capabilities are
best suited to it's needs and has
put it's own developments aside.
Konami is also planning to build
the equipment in its subsidiaries
in the US, UK and Germany.

Expectations are that the net-
work will allow its participating
members to run local, regional
and national tournaments, im-
prove management efficiency,
decrease maintenance &attract a
potentially larger customer base.
