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.

Removal/Access of Monitor and CD Player - Countertop

1.  Turn off the game and unplug it from its power source.

2.  Remove the lid (for lid removal instructions see the decal located inside the rear door).

3.  Remove the touchscreen controller and disconnect the touchscreen controller cable from the

back of the controller. Also, disconnect the Molex connector connecting the orange and gray
wires from the touchscreen controller cable to the main harness, and the green wire with ring
lug, that is attached to the metalwork, next to the controller. See Figure 1

 

for touchscreen

controller location.

4.  Disconnect the monitor signal cable from the motherboard. See Figure 1.

5.  Remove the four nuts securing the monitor chassis to the main chassis; two nuts are located

on each side of the monitor board. NOTE: BE CAREFUL TO AVOID THE FLYBACK
TRANSFORMER AND HIGH VOLTAGE WIRE RUNNING TO THE MONITOR. See Figure 2
for locations.

6.  Disconnect the monitor power connection (black and white wires running from monitor board to

right angle connector plugged into power supply).

7.  Pick up the monitor assembly and remove it from the cabinet.

8.  The CD player is located underneath the monitor assembly.

Degaussing

Degaussing your Monitor

If your monitor is displaying “purity problems,” (a display with purity problems will have parts of an all-
white screen affected by blotches of color) the monitor needs to be degaussed using a “degaussing coil.”
A degaussing coil is a circular electromagnet, used to cancel out any stray magnetic fields that may build
up on a metal object.

All of our monitors have built-in degaussing coils that are automatically activated on power-up. If your
game is experiencing minor purity problems, try powering down the game for 5 minutes and then
reapplying power to activate the degaussing coil. If the problem is not corrected, you will have to use a
manual degaussing coil.

Follow the instructions below for degaussing a monitor.

1.  Plug in your degaussing coil.

2.  Hold the coil about three feet from the monitor, press the trigger to activate the magnetic field (for

circular-shaped coils, orient the coil so you see the monitor through the hole in the middle; for wand-
shaped coils, point the wand towards the screen).

3.  Move the coil in a circular motion around the face of the monitor and slowly approach the game.

4.  Continuing to move the coil in a circular motion, slowly back away from the monitor.

5a. CIRCULAR-SHAPED COILS: When you are about three feet away, quickly turn the coil perpendicular

to the monitor and release the trigger.

5b. WAND-SHAPED COILS: When you are about three feet away, point the wand away from the monitor

and release the trigger.

Monitor Colors Adjustment Procedure

For adjusting the colors on any of our monitor types, we suggest following the procedures described
below.

The vertical/horizontal controls and brightness/contrast controls are located on the monitor control panel,
Velcroed inside the game. The monitor RGB controls are located on the monitor neckboard. Adjust the
RGB controls until the screens look as suggested in the following steps.

Ducksan/Telco/Tatung Monitors

1.  Set the game to the Run 21 game screen.

2.  Adjust the vertical and horizontal size and vertical and horizontal position to make sure that the game

screen fills the monitor screen and that the game screen is centered.

3.  Adjust the brightness and contrast controls until the playing cards are a light, ivory color. (Adjusting

the brightness and contrast can also correct for a lack of sharpness in the picture.)

4.  Exit Run 21 and enter the Hoop Jones game screen. Make sure that the court surface is greenish in

color and look for a clean, white border around the number on the player’s jersey.

5.  Exit Hoop Jones and enter the Great Solitaire game screen. Make sure that the game background is

a light, greenish-gray (may be bluish-gray for Tatung monitors).

Re:

Over-torquing the screws, securing the I/O board standoffs to
the motherboard, in Megatouch XL games.

When reinstalling the I/O board on any XL game, be 

extremely

careful

 not to over-tighten the screws securing the I/O board

standoffs. Over-tightening can cut traces on the board, causing
the board to short out when power is applied.

Merit recommends 

no more than

 9 in./lb. of torque for tightening

the screws. It is also necessary to replace the existing sems
screws (screws 

with

 star washers) with #6-32 x 1/4 machine

screws (screws 

without

 star washers).

If you have any questions, contact Merit Customer Service at
1-800-445-9353.
