Picture Lock

PROBLEM: The picture cannot be locked into
the correct orientation. The particular
nonitor I encountered would only lock in
horizontally in such a way that the ends
of the picture would be in the center,
(i.e., the picture v.Uuld be split in half
horizontally with the ends of the picture
at the center of the screen with a large
black space separating it).
POSSIBLE CAUSE: '!he HA11244
horizontal/vertical processor hasn't, in
my experience, failed very often -but in
this case the nonitor was mounted in a
cabinet in such a way that some kids stuck
a screwdriver through the vent screen and
adjusted the controls.
The controls for the Vertical Linearity
and the Vertical Height had to be replaced
because they cane apart and some of the
pieces were missing. After I replaced
these controls and readjusted the other
ones, I could get sufficient vertical
height and it would lock in vertically
-yet the only way the picture v.Uuld lock
in horizontally was in the way described
above.
In addition, the Horizontal Frequency
control alnost had to be totally
counterclockwise before it would lock in,
and even then it was none too stable
horizontally.
After checking everything I decided to
replace IC501, the HA11244 chip under the
silver box. This proved to be the problem,
as I resubstituted back in the suspect
HA11244 and it went back to the sane
problem.
The failure in this case was obviously the
result of. tarrpering, but there is a
tendency for a small screwdriver to slip
too far through the Vertical Height
control and make contact with the silver
box when the adjuster is trying to tum
this control.

Wedges/Ledges Claws Plush

A Crane is a machine that gives away
plush. One particular plush machine is
also giving away the claws!
A plush and crane machine which gives away
plush-- and its claw as well? This feature
was developed by Wedges and Ledges-- by
accident, I hope. The problem is a result
of poor "back yard" design.
Liz Gannon from Wedges and Ledges referred
ne to Phil Lenod from Pals Merchandising.
He has lost three claws in three years,
and he felt that this was nonnal operation
for the machine!?
Wedges and Ledges knows that they have a
serious problem. 'Ibey are currently
selling a $19.95 fix kit consisting of a A
several dollar micro switch and a 25 cent •
bracket. A steel chain actuates the
switch. (I predict the chain will eat the
micro switch.) This kit will be returned
to Wedges and Ledges with my blessings.
So much for American Creativity! Make a
game that doesn't work, then sell a kit at
5 tines the cost to try to repair it.
Hallelujah!
Wedges and Ledges' crane machine has two
critical defects. '!he first is that the
claw can go all the way down the payout
hole and lock there. Secondly, the player
can reach alnost to the top of the entry
where the the plush is located! (I had a
customer get his arm stuck in the payout
chute for over twenty nrinutes.)
Because Wedges and Ledges is not doing
anything to help the problem, I will see
what has to be done to get the machine
working properly. Wedges and Ledges has
also attached the crane cable to the motor
with wire. It was explained to me that
A
this was done so that the customer could •
not destroy the cable when stealing the
claw!
