The touch screen function for one of my MP90 systems is not working. Everything else works but is not responding to touch. The model for the display itself is M8033C. I already tried calibrating it, but it will not allow me to calibrate screen. Any help will be greatly appreciated. Thanks.
Probably wrong port on the back of the MP90 CPU. The MIB ports are soft-configured to support the monitor. Move the RJ-45 plug to the monitor amonst the 4 MIB ports on the bottom of the CPU until the touch screen function returns, or enter the "service mode" (requires password) and re-configure the output to the monitor with the soft keys.
