Hi,
Normally, if I connect Touch Screen to the control board and power up the switch with the SD card, Touch Screen might to wake up and start installing the firmware.
However, my one doesn't wake up.
I certainly connect them and insert the firmware to the SD card.
What is wrong...?
I solved.
I only connect the ribbon cable in front of the Control board.
I think that ribbon cable should not twist too strong.
Thanks.
