If the screen is lighting up for a fraction of a second when you turn on & then goes dark, this indicates a fault either with the backlights on the screen or the inverter part of the monitor. You can check the backlights if you have access to a backlight tester, you need to remove the rear cover & connect the backlight cables into the tester, if this checks ok then look for a problem on the inverter board, checking the capacitors for any signs of distress.

Ghosting My monitor suddenly has dark gray lines going horizontally all across the screen! The lines range from dark gray to light gray in colour and vary in thickness. These lines seem to sometimes correspond with things onscreen (for example this text box has lines extending out the top and bottom to the edge of the screen) but not always (if I am in microsoft word or something with a blank document it still has annoying lines) The screen itself also appears darker (less bright) than it used t

I have the same issue with my dv1000 "If I press the switch at the top left of the unit ( the one that puts the unit in standby when the lid is closed), the screen comes to life momentarily sometimes for 15 to 20 seconds.

My monitor only comes on for a few seconds and then goes very very dark, although the content is still there somewhere. But here's where I differ from the majority, if I can get to run System restore, the monitor will work perfectly fine again until the next morning when I need to switch it back on again. Unplugging the power lead from the back and utting it back in again will relight the screen for about two seconds before it all goes blank again.
