any way to turn off the display while keeping USB connected?

Ramps 1.4 with RepRapDiscount full graphic controller. When I don't use the prineter I turn off the power supply but the display remains on because the ramps/arduino is connected via usb to a always-on pc.

Is there a way to make the display turn itself off when idle? I don't want to ruin the backlight or some pixels over time...

Thanks!

[reprap.org] suggest backlight and all other parts are connected to 5V and GND through EXP1.

If you take out power from board, SD card and buttons lose their power. So there is no easy way to do that.

You could try this,

He cuts the 5 volt wire of the usb cable, for another problem.

You will not be able to use the adapter for programming. But it should work
