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.)
