Find somebody with an old CRT-style monitor -- they are essentially WORTHLESS -- because they take up too much space, and not as nice a picture as an LCD, and offer to take it off their hands. Use it as a "test" monitor.

Or, it could be the video-card in your SEVEN-year-old computer.
Try replacing the video-card -- some friend probably has a "dusty" and "spare" video-card that can be temporarily used.

The l226wtq goes black


Try shining a flashlight on the screen, or without the flashlight, try to see if you can distinguish anything on the screen at all, if you do, the backlight is dead, or the monitor has an internal most likely unfixable problem.
