Broken BENQ FP731 LCD Monitor

Hello,

I have a BENQ FP731 monitor that does not work correctly and was
wondering if it is worth fixing.

When you turn it on the power light comes on, you see the momentary
BENQ logo flash (screen looks normal) and a second of video from the
computer and then the screen goes black. When the screen is black the
power light stays on and is green, if you turn off the computer it
goes into yellow standy. I asume the signal section is working, but
something is shutting down the LCD. If I turn it off and turn it back
on with the power button it does the same logo + 1sec of video then
black screen again.

Any ideas? Is this a common fix?
