Troubleshooting Your Touchscreen

Problem 1

The touchscreen appears to lose calibration if you touch the screen while
touching the metal on the cabinet (this particular problem is most likely to affect
upright and cabaret games, not countertops).

Solution Make sure the controller and/or the cabinet is properly grounded. NOTE: For the

19" upright, you may have to remove the paint from the hinge that the ground
braid is attached to in order to get a better connection.

Problem 2

The touchscreen won't calibrate correctly. This is a vague problem that requires
more information to determine the cause. To investigate further, go to the TEST
SCREEN mode and slowly pull your finger down the screen in a vertical line.

A)

If the crosshair moves in a wavy line (sine wave) then there is a bad EEPROM in
the Microtouch touchscreen cable connector.

Solution Replace the touchscreen glass. NOTE: TO PRESERVE THE VALIDITY OF

YOUR WARRANTY, CONTACT MERIT TECHNICAL SERVICE (at 1-800-445-
9353) BEFORE ATTEMPTING ANY SERVICING.

B)

If the cursor generally follows your finger, except for one particular area on the
screen, the EEPROM is not correcting for flaws in the touchscreen glass.

Solution Repair or replace the touchscreen glass (or you can try switching touchscreen

controllers, if you have another one. This can cause the EEROM to reinitialize
itself, leaving you with both controllers working).

C)

If the crosshair moves continually towards one of the corners (the same corner
each time), every time you run your finger down the screen, the touchscreen
glass has a broken wire.

Solution Return the glass to Merit Technical Service to have it fixed.

D)

If the controller works for a while, but stops working (the TTL LED does not
respond to a touch), the controller may not be properly grounded.

Solution Install the TTL Ground/Static kit (#SA1089-01) and the CRT-266 Electro-Static

Discharge Board kit (SA1088-01). On the upright model, you may want to check
the gray and green wires from the touchscreen controller cable. They should be
attached to the ground on the power supply.

Problem 3

If the glass is totally unresponsive, check the LED on the touchscreen controller
(board).

1.

If the LED isn't flashing, touch the screen while keeping an eye on the LED. If the
LED reacts to your touch (i.e. gets brighter), the problem is with the CRT-260
board.

a) The U41, UART chip has been minorly affected by a static hit.

Solution Turn the game off, then power up. If that fixes the problem, call Merit Customer

Service for software that can prevent this problem from happening again.

b) The UART chip or the U39 Maxim chip (on the upright model) has been burnt
out by a static hit.

Solution Call Merit Technical Service at 1-800-445-9353. NOTE: Make sure to install, if

you haven’t already, the SA1089-01 Ground/Static kit to help prevent this from
happening again.

If the LED is flashing, refer to the following chart for interpretation of the error and contact

Merit Customer Service.

Advanced Touchscreen Calibration

The following directions will help you calibrate your touchscreen more accurately.

1.

Enter calibrate mode. When the first dot appears, intentionally touch the screen about 1”
away from the dot, diagonally, towards the center of the screen (repeat this procedure
for the second calibration dot; see Figures 1a and 1b). You are now in TEST SCREEN
mode. As you test the screen, you should notice that the crosshair is considerably out of
calibration. By completing this step, you have shown that the machine is accepting
calibration input.

Figure 1a

Figure 1b

2.

Go back to calibrate mode, but this time touch exactly on the center of the calibration
dots, to more accurately calibrate the screen (see Figures 2a and 2b). You are now
back in TEST SCREEN mode. 

Touch

 

the approximate location where the first dot

appeared

. If the crosshair is not centered on your finger, note the direction and

approximate distance which it is off center. Repeat this procedure 

at the approximate

location of the second calibration dot

 (see Figures 2c and 2d). (If the crosshair is

centered on your finger, the screen is calibrated accurately.)

Figure 2a

Figure 2b

Figure 2d

Figure 2c

3.

To compensate if the screen is not calibrated accurately, return to the calibration
screen. Recalibrate the way you normally would, but don’t touch exactly on the center of
the dots. This time, touch slightly away from the dot

, 

in the SAME direction and

approximate distance

 which the dot was off center (see Figures 3a and 3b). For

example, if the crosshair comes up slightly below where you touched, when you
recalibrate, touch slightly below the calibration dot, if the crosshair appears slightly
above and to the right of where you touched, when you recalibrate, touch slightly above
and to the right of the dot. This should compensate for the individuality of the
touchscreen glass and the way it was mounted on the CRT.

It may take several attempts to get the screen calibrated exactly.

Removal and Installation of Microtouch Touchscreen Glass Overlay

Removing the Touchscreen Overlay

1.  Remove the monitor assembly as explained in the 

Cabinet Information Section - Removal of

Major Parts

.

2.  Remove the first layer of black tape around the edge of the glass.
3.  Spray alcohol over the second layer of tape to loosen the adhesive.
4.  Carefully cut the second layer of tape by running a razor blade along the gap between the

monitor and the touchscreen overlay.

5.  While continuing to spray the tape with alcohol, remove the remaining tape by CAREFULLY

running the blade under the tape and gently peeling it up from the glass. Do this until all tape and
adhesive have been removed from the glass.

Installing the Touchscreen Overlay*

Countertop model:

1.  Place the touchscreen glass over the monitor glass, so that the touchscreen cable is to your right

(when facing the monitor).

2.  Apply one piece of the black, double-sided tape to each edge of the glass, to hold it to the

monitor.

3.  Apply the black cloth tape around the entire perimeter of the monitor, securing the touchscreen

glass to the monitor and covering the double-sided tape.

4.  Place the monitor assembly back into the cabinet and secure it in position.
5.  Run the cable through a hole on the side of the monitor chassis and into the CPU section.
6.  Attach the touchscreen connector to the back of the SMT-3 controller.

Upright and Cabaret models:

1.  Place the touchscreen glass over the monitor glass, so that the touchscreen cable is to your right

(when facing the monitor).

 

Upright models only*:

 

Install the supplied foam tape around the edges

of the monitor, where it meets the bezel.

2.  Place the monitor assembly back into the cabinet and secure it in position.
3.  Run the cable through the rear of the cabinet and into CPU section.
4.  Attach the touchscreen connector to the back of the SMT-3 controller.

* When installing a new touchscreen overlay on a 19” upright model, make certain that the metal of the
monitor bezel door does not contact the glass. The bezel should fit snugly against the foam tape,

WITHOUT CRUSHING THE TAPE. 

You must also recalibrate the touchscreen after closing the monitor

door.
