hi i have a c7000 machine with an intermittent touch screen and key pad.
the screen displays okay, except there is intermittent response from the touch screen.
similar for the keypad sometimes it works and sometimes it doesnt.
for the screen our current workaround is to plug in a mouse, for the keypad i can plug in a USB keyboard but i have not found a combination to access the admin settings.
what components would i need to replace to fix this problem ? the entire screen or entire keypad or some control board ?
thanks
