If connections are OK then check for bad wires by wiggling short sections of the cords while monitor is on, see if anything happens.

If you don't get any reactions from those tests...
Is it a skinny LCD flat screen or a big heavy CRT flat screen monitor?

If not heavy can you move it around or shake it to see if that makes it go on/off??

It would be one way to maybe find out if it is an internal problem or external.
internal not as easy to fix, a wire or connector can be replaced.

Hi there!

I'm wondering if the little 'on' light on the front of your monitor goes out or does it stay on when the monitor appears to have switched off?

The reason I asked about the 'on' light was that if it was an LCD monitor, then maybe there's a part in there that might be on its way out or flickering ready to fail.

I don't have an LCD monitor and not sure if you do, but maybe the back light might be the only problem and if that is the case then I think that can be replaced.

I'm just guessing here though... could be so many things.

Thank you Jo and Lara. The monitor is LCD skinny flat screen. I will try all those things.

also dont be afraid to try a new cable. i dont know how many times sive gotten to a clients office and they were so in need of a monitor and went to buy one and it was just a bad cable from the computer to the monitor.

but if your selling it at a flea market put it out and sell as is.....

Thank you Roger. That may very well be the problem. I hooked up the monitor in question and in doing so I noticed that the bottom screw could not be tightened up with the nut? I'm not sure what they're called. I will look at it again when I feel better. What has me more concerned at the moment is that my puter crashed after hooking up the old monitor. Since the old monitor in question kept blinking I could not tell much of what it was saying. I did see that Windows Vista would not come up. After hooking up my current monitor my puter checked for errors and then it asked me if I wanted to do a system restore. I wonder why my computer crashed when it was turned off when I hooked the old monitor up. I thought that monitors were plug and go?

the funny thing withmonitors is... that if the older monitor had a resolution set to high it would also make the monitor not show a picture. i have had this happen a few times over the years. so i usually set up a new monor that i know is better and if it turns on then i set the resolution a bit lower. like standard 640 resolution then gradually build it up to 1024x 768 . whichis where i keep mine at. it can go up almost three times that but then everything would be soooo small...

try with the monitor that works. to set it up to a lower resolution. then turn off computer. hook up old monitor with a new cable and see if the picture comes on. if it does boot up with it then you can change monitor resolution a bit highr at a time to see when it brok at.


sound good...

That is odd - I don't think the monitor should have caused anything like that.. it's just a screen to show what the computer is doing...

Let us know if it OK after you get it all back to your normal set up.
