Troubleshooting
Display Image Inverted (Rotated 180°)
Disconnect and then reconnect the LCD cable connectors. To open connector
J660, insert your thumbnail beneath the dark brown part (hinge) and the cable.
Carefully lift up the hinged brown part to release the cable. Reseat the cable and
close the hinge. J660 pin 1 must 3.3 VDC for correct display orientation.
Touch Screen Does Not Operate
Try the following:
Disconnect and then reconnect the touch screen cable connectors.
J4 pins 1-8: verify that pins 1, 2, 3, and 4 of connector J1 are at +3 VDC
when the touch panel is not pressed. Verify that pins 1 through 8 toggle their
value when the touch panel is pressed.
If these do not resolve the problem, replace the touch screen panel.
