Screen Issue
Hi all,
I have an inspiron 8100 laptop and my screen seems to be no longer functioning. What happens is that the screen will flash red for a moment and then go black. This happens on power-up. I checked the screen and the LCD is working, I held a flashlight up to it to see the picture just no backlight. I was wondering is the backlight dead or is the power inverter broken?
Thanks

To test out your LCD do the following.
Attach the system to an external monitor to see if the problem occurs there. If video shows properly on the external monitor, it may be possible that the LCD is no longer functional.
If the problem occurs on the external monitor also, then it may be possible there is a problem with the video card or video drivers in the system.
Some systems also have a small plunger that detects when the lid is closed and activate power management features. If your system has this, depress this plunger several times to see if this changes the effect.
Also see if there is any change in display while moving the screen back and forth.
Also try running the Dell diagnostics on the system to see if the problem occurs in diagnostics as well.
