Hi I know you probally don't support this monitor any more but could you tell me possibly why it would go blank (black screen) and a minute later come back on. I am not typing or touching it, just watching television.
Thanks for any help you can give me. It is running from a Gateway GM5442 system with Vista.

elvisy71, If different monitor will display the Win-desktop screen with no problem, then Gateway 2275w will need you or qualified electronics technician to possibly repair a defective internal "switch-mode-power-supply" / CCFL inverter supply" !! Check the status of unit warranty first, and check to see if Gateway has a swap-out (exchange+cash) program. If that dosen't work you will be doing a lot of reading about DIY lcd monitor fixes. You will also need to view some DIY video clips at YOUTUBE on "lcd monitor disassembly" and "lcd monitor repair" that will help you decide what to do about your now BLACK or BLANK n BLACK screen unit. You can find tons of DIY stuff here on fixya in my and other CCFL back-lit lcd monitor tech's fixya profiles. Elvis, remember this! Your 2275w isn't any different than any other brand of ccfl back-lit lcd display in it's basic design and operation and some can be DIY repaired for under $6 in parts cost. Just do some reading of the higher numbered (>16) pages in my fixya profile and my old profile "louie12fix" and follow the web links you find there. If this was of some help to you please come back to fixya and rate this response and tell me and all the other black screen lcd owners what you are planning to do about your monitor. 12fixlouie 42610
First make sure that all the cords are connected properly from the back of the CPU to your Monitor.I suggest you to unplug all the cords of the CPU and then plug them back in after 10min. and make sure they are all connected tightly.Next check if the power cord connected to the Monitor is attached tightly.
If you still face the problem then you will have to replace it with a new power cord whih connects the CPU to your Monitor.It is black in colour.
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.
