My computer monitor is a black screen....the light is lit solid green and I can hear the software playing just no picture

If the light is green, I suspect that the backlight has gone out on you. This could also be caused by you having the brightness turned all the way down.

Screen trys to show desktop, but quickly fades to


Since the power led button is on, the problem with your monitor is the that the picture board of your monitor has develop fault, that is why it tries to show your desktop and quickly fades away.

The picture board of your monitor is bad and will need to be replaced in other for it to display.

The best thing for you to do is to take your monitor to a local repairer or any service center within your vicinity to help with the replacement of your picture board because the fault is not something you can fix on your own in other not to complicate issues.

Take care.

Gateway FPD1750 monitor's keep go black screen, no picture at al

tgordon60, If you know how those NEW "CURLIE-Q" energy efficient CFL light bulbs produce WHITE LIGHT, then you will know what makes an LCD display panel produce all the pretty colors and the WHITE BACKGROUND of the FIXYA web page!!! Only difference is that your "cold-cathode-fluorescent-lamps" are thinner and straight, and hung on rear of LCD glass panel and have a DC to AC electronic ballast called an "INVERTER" circuit to produce 600 to 1000vac to light them up. Get to my FIXYA profile and read my responses to other BLACK screen lcd owners to learn about all your options for repair. Follow any of the links to other web pages you find there. Your monitor not any different than ACER, DELL, VIEWSONIC, BENQ, SONY, AOC!!!!! 12fixlouie aka louie12fix

Lg2234s monitor goes of blinking...cant turn monitor off (blue light remains off) then monitor turns on ..screen pic returns but is totally green, the OSD becomes garbled, if set to return to default then...

emale36, Could be problem with the "switch-mode-power-supply" inside the unit. If dc voltage rail is noisey or marginally on the low side of rated specification then strange things will start to occur on screen. Contact LG (Lucky-Goldstar) if unit is covered by warranty. The unit will need to be evaluated by technician. Visit YOUTUBE to see video clips of monitore being repaired by their owners. Read more of my profile responses to other LCD owners. 12fixlouie

Monitor Not Showing A Picture. Light flashes Yellow and Green.

use the onboard graphics instead of a seperate graphics card (if installed) to test the screen.if it still doesn't work then unplug your monitor from the mains supply and plug in again to reset it. i doubt it's your monitor that is the problem though. but look on the back of your pc for another connection for your screen. the onboard graphics connection is normally vertical near your ethernet port and mouse and keyboard inputs.

please rate me and give me a fixya! if it helped.
