When it's turned on, the light on my monitor blinks but the screen doesn't display anything. Why might this be happening, and how can I fix it? It's two years old and it worked fine until today. I always keep it on, but today I turned it off and when I tried to turn it on again, it didn't work. PC works well with other monitor
Thanks for solution1, but I unplugged the vga chord and plugged it again. Also, the light flickers when I turn power on, even if PC is not on, which makes me think that might be a problem with either something in the monitor or, perhaps, the switching adapterThanks for solution1, but I unplugged the vga chord and plugged it again.

I have to add that monitor usually had a fixed green light when working and a fixed amber light when pc was shut off, after displaying a "no signal input" signI have to add that monitor usually had a fixed green light when working and a fixed amber light when pc was shut off, after displaying a "no signal input" sign

Check for blown capacitors on the power supply board, this is a very common problem with LCD monitors. Here is a link to a web article showing what to look for. The second link is to a source for capacitor repair kits for that series monitor.
Disconnect the lcd from the computer. Turn on the LCD and see if it still flickers fast. If it doesn't then go ahead reconnect the lcd back to the computer. If its still flickering, then go ahead and hook it up to another laptop or desktop. If it doesn't flicker on another computer then that means there is a problems with the video card on the original computer.
If it still flickers then that means the lcd is bad and would need to be replaced.
It could be the Monitor, the VGA adapter, or the PC itself. If you power on the monitor without anything connected to it, do you ever see anything on the display?
If not, it is probably the Monitor. If yes, it is likely the vga adapter and/or PC.
I was called to repair similar incident last week. A Compaq box (don't remember the model) with a 'smart' usb keyboard. By this I mean that the keyboard had a row of what I'll call hot buttons. The client had pushed a button with a moon on it causing the monitor to go into sleep mode. I suspect that whatever key you pushed had the same effect.
After plugging a known good monitor into the faulty box I verified that the box was OK. This left me to think the monitor itself had a problem. Plugged the suspect monitor into a known good machine.. and it worked fine!!!
Set machine and monitor to original configuration and still had no video. Decided that the monitor was too smart for its own good and maybe there was something in the monitors menu. Pushed and held the 'menu' button on the monitor for a few seconds and menu comes forward. Green power led also comes on (surprising me) so I powered up the computer and lo and behold the problem is fixed!
