I believe the max resolution this LCD can support is 1440 x 900 / 75 Hz. If you set your display resolution higher then that, you will receive the input signal out of range error. Your LDC turns off to protect it self from the invalid settings. If you can not change it back once your PC boots to windows, you may have to do it in save mode by pressing F8 once you power on your PC and before the windows loading screen starts. Regards,Chris
What happen when you hook this monitor up to other PC that has the video setting 1280 X 1024 60 Hz? Just ant to narrow down the problem before opening up the monitor. You may have logic problem in the logic board. If it does the same with other PC, then open it up and inpsect the inside for such thing as failed caps on the logic board or on the main power supply board, I think more likely to be ROM chip on the logic board is scrambled.

change windows resolution and refresh rate to 1024 X768 and 60 Hz. start->control panel->display->settings-> change the screen resolution to 1024 by 768 pixels-> advanced-> monitor->change refresh rate to 60 Hz-> ok-> yes -> ok.
There may wrong setting of refresh rate. Most monitors work at 60 to 70 Hz refresh rate. Above that they tunned blank screen or out 0f range message displayed. Also check the output video signal. Please confirm technical specifications from the documentatation of the monitor.
