Hardware problem

Why your new bought 7-inch LCD has no display when power on?

Answer: It is very normal. Embest default delivered board is preloaded with 4.3-inch LCD image. Please refer to "Devkit8500 Quick User Manual.pdf" provided in product DVD to update the image for 7-inch LCD. Sorry for any inconvenience brought to you.

Why the touch screen could not be used when getting into WinCE system?

Answer: When getting into WinCE system, LCD displays as below, there is no response when touching the cross in center by figure.

There are might be two reasons:
1. The provided touch screen is resistive touch screen, so please use touch pen to click the center cross not use your figure;
2. It needs about 1 second touching time for calibration, if the touching time is too short, the operation will be regarded invalid.
