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. 12fixlouie on fixya.
bonannorl, Can you see the WIN-desktop with flashlight when connected to fully booted PC to determine status of units SMPS? Will you do DIY fix or trade unit for new. If you read my older posts on fixya you will be able to make decision on what action to take with your Gateway lcd display. Your monitor still works. It just needs a little work to enable SMPS/inverter circuit to sustain voltage to light-up the CCFL tubes that provide white light so you can see what is on the screen. Some tech type people repair their units because they understand the top 1 or 2 causes of ccfl lcd monitor failures and know how to do the inspection and common repair for black n blank or black screen problem. Sure, when my Jan 2006 Gateway goes to black screen, I will open it, and attempt a DIY fix if only to keep it as a working spare. 12fixlouie bonannorl, Can you see the WIN-desktop with flashlight when connected to fully booted PC to determine status of units SMPS?
