Screen goes black after booting up

amprich63, You should try to evaluate the state of the "switch-mode-power-supply" in the F1503 unit. Reconnect it to a FULLY booted KNOWN GOOD PC that is currently displaying the WIN-desktop screen! Then and only then push the "ON" button for the F1503. Did you see the desktop window?? if only for 1 second? What did you see next? Did you see a BLACK and BLANK screen? or Maybe just a BLACK screen? Do another post to this and tell me EXACTLY what you see or don't see when you shine a bright torch 2-3cm from lcd panel!!! I think you may have a BACKLIGHTING or POWER SUPPLY problem. I'm12fixlouie on fixya. if this was of some help rate this on fixya
