Try going into the control panel and select power options see if there is way to adjust the display brightness or try holding down the "Fn" key and use F7 to increase the brightness

The screen goes very dark within a minute after booting up = I can just barely see the menu page


When you say screen goes very dark when it booted to windows so it means that when you turned on the laptop when the dell logo flashes the screen was fine? if thats the case could you please try this. after turning on the laptop you will see the dell logo flashes immediately keep tapping on F2 and then it will show you the BIOS setup utility, please check if in BIOS setup display goes dark as well. If yes then try this, after turning on the computer when dell logo flashes keep tapping on F12 to boot menu then select utility partition to run the diagnostics. Please run test on the LCD check if display goes black when running the LCD test. Then try this when you sees the dell logo keep tapping on F8 to boot in safe mode check if in safe mode display goes very dark. Try this too, boot in F8 then select last known good configuration check if the settings on your display will be fix. If you can boot to safe mode no problem then uninstall the display or video driver. then restart computer.
You can also try to connect an external monitor if you have one just try to isolate if issue is on the LCD or the video card. If the display is dark as well in external monitor then video card needs to be reseated if fails then replaced. In situation like this most video cards is integrated to the motherboards. So replace motherboard.

My Emac will boot up but it will not light up.What can I do?


Look closely at the screen, can you still see the icons in the background?
If you can and it seems extremely dark. then your problem is likely an lcd inverter board. This isn't a terribly expensive part but getting it replaced might not be cheap labor wise. An lcd inverter is what powers the backlight for the screen.

Backlighting issues on tv set (I think). Screen goes extremely dark after about 30 min. of viewing. Does not return to orginial brightness unless unit is left off for a long period of time


Lcd tv sets are lit by small glass florescent tubes called cold cathodes and, are powered by: ballasts called inverters... these go out just like your office florescent lighting the parts can be purchased online from electronic parts houses and, are easily replaced

My ViewSonic computer monitor keeps displaying a Vga Not Support Message upon booting then the message Out Of Range comes up on a completely dark screen. Need Help


It sounds like the computer is trying to use a resolution that the monitor cannot handle. Boot into safe mode by pressing the f8 key during boot up and select safe mode. Once booted, right click on the desktop and select properties. In settings lower the resolution by moving the bar to the left and reboot.

I would move it all the way down, you can then move it up a step at a time once you are in normal mode again.

Hope this helps

When I turn on my monitor I can see the Gateway letters come on the screen but then it just goes dark again. It comes on for a split second and then goes dark again.


joel_herrera, Yes, this is a very common symptom of a failing Switch-Mode-Power-Supply and/or Inverter circuit! Very common in 2-4 year old lcd/fpd's. How old is your's? Do you have warranty? Have you tried the Flashlight test? DO THIS! Reconnect lcd monitor to your fully booted PC with a known good WIN desktop screen. Then power "on" the HD2201 and tell me what happens and what you see or don't see after the screen goes BLACK! Shine a bright flashlight onto the screen at different angles and let me know the results. I'm louie12fix on fixya or lmistyrel @aol.com BYE
