I have a PD3200u that won't turn on. The computer recognizes the monitor and I can adjust all the display settings. No LED on the power button and no controls. I never see the bootup screen when powering or plugging in the monitor. I made sure the power switch was in the correct position and have tried different cables.
There is a touch-sensitive power button on the bottom right corner of the front of the screen. Have you pressed that?
