Monitor picture comes on for only 1 second and then it is blank (black) Color bars appear to be OK (for that second) when running the Self-diagnosis function.
timothy henr, Do you understand how the new screw-in, curlie-Q, energy efficient, CFL light bulbs generate white light?? You will when you find out just what makes the WHITE fixya background on this web page you are looking at!!! Black screen of death can strike at any time!! Do a reply when finished with your research of repair video clips at YOUTUBE. Your search terms are: "lcd monitor disassembly" and "lcd monitor repair." That should get you started. Your unit could have a "switch-mode-power-supply" that detects a problem with itself or another circuit and goes into "full" or "partial" shutdown mode. You should be able to tell the difference if you shine a bright flashlight 1 inch from screen when it goes black!! Partial=still see win-desktop. Full shutdown=no see desktop!!! What wil you do??? Fix or just trade up for new display?? 12fixlouie
