You need to inspect and look at the pictures of failed monitor per Louie advise so you can make up your mind if you want to DIY repair or not.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, 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 monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Kancanara, You will need to contract out the repair work ($40 to $90) or DIY investigate the "switch-mode-power-supply board/CCFL inverter supply" to determine exactly what electronic component(s) has failed, and more importantly WHY!!! Your unit will be 5 years old in 4 months! Did you notice if the WHITE web page background was getting a little PINK instead of pure WHITE? Have you performed the "flashlight test" to determine the "shutdown state" of unit's "switch-mode-power-supply"?? Have you verifyied proper operation of your PC with substitute "known-good" monitor? Will you be doing the repair after viewing some lcd monitor repair video clips at YOUTUBE?
Let us tech's here at fixya know your intentions as to exactly what you wil do. You should also spend some time researching the fixya profiles of "budmrtn" "buddymc" "12fixlouie" "louie12fix" here on fixya before making any decisions. 12fixlouie

Monitor goes Black off and on .....


I had the same problem for about a week and solved it yesterday by downloading the latest driver by NVDIA who makes my video card (NVDIA GeForce 6200).
I had previously updated the latest Sony driver for the monitor. It did not solve the problem but could be part of the solution in conjunction with the new video card driver.

LCD Monitor Goes Black during Use


I had the problem sometimes, but then I connected a second computer to the analog input and found out, that the screen didnt turn black but switches between the inputs on an on.

I found out that the "input" button seems to be short or damaged, as the behaviour was invertable by pressing the button. I blew into the button some times (a very naive solution, yeah) but it worked, the switching stoppped.
