MERIT INDUSTRIES Megatouch XL, Technical Service Reference Manual

Page: 18 / 65

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.
