Question about Gateway FPD1976W LCD Monitor
When the computer turns on for ten minutes or more the sheiled comes up and the screen turns black and white. I want this problem corrected
If the screen is all white light then you can have a number of problems.
One could be a bad video board, the next could be a simple loose wire from the video board to the back of the lcd screen OR a simple blown fuse on the back of the actual lcd screen can cause the same thing.
Snaps are all sround these things and can be really stubborn at times. Best to start the bottom first then work up each side to the top.
Something flat, thin and with a decent sharp edge on it will help. A pocket knife held parallel to the joint between the front and rear plastic works, you can also sharpen the edge of an old credit card with a file (nail file works) This isn't as strong as a blade , but safer if you slip !!

wjfarm48, Sure sounds like a power supply problem. How old is it? How many hours of use? Do you understand what a switch-mode-power-supply and an inverter supply is? If not, then here are your options. Check with Gateway to see if there is a swapout program. You box up and ship them your monitor+cash, and they return a REFURBISHED same model with new CCF tubes and inverter/SMPS. When you box up the monitor, follow this lead. "A 3 inch thick layer of breathable air shall be the only thing touching the lcd front panel" Next option is find some local TV/Monitor repair guy who can get parts and or replacement boards/CCFtubes from Gateway. Last but not least, is to repair yourself. Not Recomended.. But do a search on lcd monitor repair or Bad Capacitors In LCD Monitors or Repair of SMPS in LCD/FPD Monitors. Also check for videos on YouTUBE related to lcd monitor repair just for your own info. Here 's what you are dealing with. The light that makes your FPD bright white is generated by Cold Cathode Fluorescent Tubes (2) that require 600-1200vac at high frequency that is generated by an INVERTER which gets 12-24vdc from the SMPS. Almost the same technology is used in the new style screw-in curlie-que Compact Fluorescent light bulbs. Only they call the inverter a electronic ballast. Anyway, thats about all the info I have. Let me know how you make out in you quest to get your LCD up and running again. I'm louie12fix on fixya or lmistyrel@ aol.com BYE for now.

The problem is not the setting on your monitor...The problem is the backlight inverter located inside the upper and lower edge of your screen..
It is busted. The backlight inverter is the light source responsible for the displaying image on your screen. If these were busted.. then the only thing you will see is black screen.
It is very risky for you to replace it by yourself if you don't have the knowledge and the right tools to open the back of your lcd..My suggestion is to bring your monitor to a credible technician to have your backlight inverter replace. if there is warranty for your lcd, please avail this.
Hope it help..
Much appreciated if you rate this solution..thanks..

davea47, Your monitor's internal "switchmode-power-supply" is probably having a problem. You may need to do some electrolytic filter capacitor replacement!!! Problem not new one!! You or qualified lcd monitor technician will need to open unit for inspection/evaluation of power supply board. Do some reading in the fixya profiles of "budmrtn" "buddymc" "12fixlouie" (me) and follow links you find there. After investigating your unit let us tech's here at fixya know what you will do to repair unit. 12fixlouie
