If your Engage Health Touchscreen doesn't switch on when you press the red power button, there are a few important things to check before contacting support. 

First, check your Touchscreen closely after pressing the power button, are there any flashing LED's on the bottom of the screen? Can you hear the cooling fans running? If so, this may indicate a fault in the Touchscreen display. In that case, refer "here"

If you see no lights, and hear no fans, that would indicate no power is reaching the screen, in this case, carry on with the following checks.

1. Check the power cable is plugged in and switched on at the wall.

2. Check the power cable is securely plugged into the back of the screen. (See here for instructions for removing the screen from the wall)

3. Make sure to test the power socket which your Touchscreen is plugged into, to do this, plug in another device to ensure the socket is powered.

4. Check the power cable itself, this can be done one of two ways, either use the cable to power on another device, like a monitor or desktop PC. Or, preferably, try another power cable from the practice, borrowed from another PC or Monitor on your touchscreen. This second method is preferable, as using a faulty cable on another device could lead to damage.
