Have you checked your energy saving settings? Try to set the monitor to "always on" and verfy if the problem still persists.
Also check if your monitor drivers have their own energysaving options, although i doubt it.

I have a gateway FPD2485W tft lcd monitor and i start my monitor and after it shows gateway it then goes black. How can this be fixed


bonannorl, Maybe it can be fixed. You did not give any history of unit. Only "now" stuff. Is unit covered by Gateway warranty? How old is unit? Date of manufacture? Did unit work fine connected to your pc and this black or black n blank screen thing suddenly happen? Is screen also BLANK? Have you swapped-in old monitor to prove PC is OK? Your CCFL back-lit lcd monitor no different than any other brand in it's basic design and operation. Get into my fixya profile and read some of my testimonials and solutions to black or black n blank screen problems to help in your decision to DIY fix or contract out needed repair work. Most likely 2485w has problem with it's internal "switch-mode-power-supply"/"ccfl inverter supply"!! Let me know more info about unit.

Are you sure that your computer isn't just going into power saving mode? Not sure what operating system you have but go into the screen savers tab or video properties and find out how your system is set up for power saving It may be starting before your screen saver does so the monitor would just go black.

Sounds like the inverter is broken or have a short circuit. This is a common failure on TFT displays.

Here is a website explaining this kind of failure:

LCD monitor goes blank


It appears that the display resolution set in your display properties is out of the range that the LCD can display.

Try this.

Boot to the ENABLE VGA MODE by pressing F8 to get the Windows Boot Menu. If you can get to the desktop, then go to display properties, and see if you can change the resolution to higher settings and maintain video. (If the video blanks out, then it should revert to the previous setting in 15 seconds)
