My monitor has a nasty habit of going out any time it feels like it, just like somone has switched a light off. It happens most of the time shortly after I start the computer but it has happened much later in the day. The off/on light remains on so I turn it off and on again and the screen lights up, for maybe 20 or 30 seconds, only to return to black shortly afterwards. It's an LCD and it's about 2YO. Would appreciate any help, Thanks for your time.
Hi Rahni, It's a very common problem. LCD's use four small Cold Compact Fluorescent bulbs to back light the display. (thats what gives the LCD it's brightness allowing you to see it) The inverter board runs these lights and when they go bad they will typically show symptoms like you have or the monitor power light comes on and you have either no display or a very dim display. If you ever have one that has no display but the power light is on you can check by shining a flashlight directly into the LCD from the front (right into the screen) if you can see an image then it's either the inverter board (most likely) or the CCFL bulbs have gone bad. The inverter board and CCFL's are replaceable. Good Luck, El Duderino
