Having problems with your Computer Monitors ?

I have a model Q7C4 when turned on it immediately turns off again even if not connected to the computer (ie power only)

Answers :

Most modern monitors will not run if the signal from the computer is not present. If you can borrow another monitor, see if it will work. If ok, the problem is within your monitor. If the new one doesn't work either, then the problem is likely the video circuit in the computer--a bad video card if it's a desktop, but a bad circuit IC if it is a laptop.
