My GX Touch 50 was plugged directly into the Cerbo GX and operating normally. I added a 3 meter HDMI cable and USB cable to bring the touch screen into our RV living space. When I plugged in the Touch 50, it did not power up. I plugged the Touch 50 USB into a phone charger and still no power up. I plugged the Touch 50 directly back into the Cerbo GX and it still does not power up. Does the Cerbo GX need to be power cycled? What do you suggest? Thanks in advance!
