Most common failure in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed Dell monitors to get some ideas what goes wrong: http://s807.photobucket.com/home/budm/allalbums Post back what you see inside so we can guide you further.
The fault is a back-light problem and the fault could be a faulty inverter board or a faulty CCFL lamp. For service, parts and DIY info check out LCD Parts WEB site, please click on this link :- www.lcdparts.net
1. Check the cable with the blue connector. Make sure it's plugged well to the back of the computer.
2. CHeck the light on the CPU's power button. If it's solid green, press the numlock key on the keyboard. Tell me, if the numlock light on the keyboard turned off or on. You can press it again if you didnt catch anything.
3. If there are no lights on the keyboard or the computer when you turn it on, the computer is the problem.
Just post here what lights are present or what happens when you press the numlock key.
Problem solved! The main power thingy (the thing with the big red wire coming out of it) was all black and dusty. There was 'soot' all over the whole insides of the monitor. I concluded that this monitor should be laid to rest, and a new flat-screen monitor erected in its place.
