WILLIAMS
GORGAR SOLENOID PROBLEM RESPONSE
BY AARON TOSTIEVIN, SERVICE TECHNICIAN, ED'S DISTRIBUTING, LANSING, Ml
W
e recently received the following
etter from one of our subscribers,
responding to an article in our April '84 issue
from Australia regarding . Williams' Gorgar
solenoid problem. Mr. Tostievin's letter reads
as follows:
" .. . I have had a similar problem with some
Williams games as described in your July '83
and April '84 Journals. On close look with a
light and telescope, I have found small solder
bridges across the control pins and power
supply pins. Also, I have found internal shorts
on the PIA chips used in the switch strobes at
the same points.
There has been just enough feedback
current to turn on the driver chips without the
game in the play mode.
The chips affected are IC5 and IC11 on the
driver board (pins 19 & 20 and 39 & 40).
To stop the problem I removed both chips,
cleaned the board, and installed low profile IC
sockets in case the problem happened again.
I have not had any more problems with burning
coils in those games since September '83."
