My Computer Turns On But The Monitor Doesn't ?

[llaurzz]

I have a Acer AL1716, recently the monitor has been turning off or refreshing when i'm on it, but now i go to turn the computer on, everything is fine but the screen doesn't switch on. but as soon as i turn the computer off, the screen will switch on and vice versa.
I've unplugged all thw wires from the monitro and back in but still nothing.

Help me please
Thanks in advance

This sounds like a computer problem and not a monitor problem. Try another monitor first, to rule that out
