Hi...

I have this problem of No Signal Meassage on my monitor for the last a month ago . It takes at least 20 minutes of time to start by using on and off button at least by 20 to 30 times .

Please tell the problem and the solution as well.

Well, if you can, test it with another monitor and see if you get the same problem.

At this point it could be your monitor, a loose cable, or the graphics card of the computer.

What type of monitor is it (make and model preferably)? How is it connected (HDMI, DVI, VGA, etc)?

Does this happen right away, even when the computer is still starting up? Or does this start happening after the computer starts up? After it is working, if you shut the monitor off, do you have to go through the whole process after you turn the monitor back on? Or does this only happen when the computer is turning on for the first time?
