of Don's Video Repair of Shelbyville, Tennessee has
written this complete Beginners Guide to Repairing
Video Card Games and 8 Line Machines.
New! Just Published. All about Switching Power
Supplies. From the very beginning! Switchers are
covered from when they first appeared in our In-
dustry up to the current models and uses.
Learn From Experience. Don has been in the
business for over 20 years and has seen it all. In this
manual, he presents the topics in a logical order
bringing the novice technician along at an even pace
while allowing the expert serviceperson to extract
the data needed to keep up these specialized games.
Theory and Circuit Analysis. Voltage Measure-
ments, Substitute Parts and Failure Modes.
Modifications. Getting negative voltages from
positive-only switchers, Identifying power legs on
ICs, Capacitor Replacements.
Theory & Symptom/Solutions. Since there are
quite a few Video Card Games on the market, and
older ones are still being operated, Don has elected
to go into depth on a few of the more common ones
and to list symptoms and solutions for a great many
others. Game pinouts and prints are included.
Troubleshooting. Peter Chou, Condor, Wico, Power
Plus, Nintendo, Sieracin, HiTron, Penn-Ray.
Never before published information outside ofour
journals. This info can not be found in any of our
current service manuals.
Covered From A To Z. The goal of this manual is
to enable anyone to repair a Video Card Game up to
and including the Printed Circuit Board. Chapters
are devoted to Tools, Testing the AC to DC sections,
and Schematic Symbols. On the Printed Circuit
Boards, the most common problems are discussed
including the Input circuits, the Video circuits and
the Reset circuits of many of the popular games.
So, if you' re looking for the definitive word on Switching
Power Supply servidng and repair, this is it. Now, you
can determine if that switcher is repairable or simply not
worth your time. Look up the symptom, perform the
solution and you' re back in business. Take another look at
that pile of useless supplies in the corner of your shop-
are they really beyond help? Maybe not!
