It can be your video card... do u happen to have another computer? If you do have another computer, then i suggest you take teh video card from this one and try plugging it in to the other one and see if it works , if not ull have to get a new video card.
If it does work in the other computer, then it might be something you did in bios. Try clearing the CMOS battery on your mobo (motherboard) [google ur mobo and look it up on google images to see where the CMOS battery is}. That should reset the bios and if you're lucky, your monitor will get a signal back.
pls be kind and rate my response... ill try best to further help you and also if u can pls write back and tell us if u fixed teh problem...thnx

Do you hear the harddrive start up? When you push the power button (or switch on the back) do the lights go out? If you hear fan running and hard drive start up then the computer itself might be on but the monitor isn't. Check the power to the monitor, the connection between monitor and computer to make sure they are all on and connected.
If you don' t hear the fan running then you have other problems. Any blinking lights would indicate something is getting power. I'm assuming the computer was working before the power button was pushed... If the monitor is actually working, you could hook up another monitor to check too then you have other problems but need more info to know what that could be.
would need to know the answer to the above questions as well as if it was working before, what was done, what changed between it working and this problem. Also what age the machine etc.
After repairing the on/off button for $100.00 and then rehooking up the monitor to my pc, the monitor has power but stays asleep even when I push in the menu button, I can't get anything to happen. HP techs tell me that the problem is with my computer although it worked perfectly fine before I unhooked all to send out the monitor.
I hooked all back up again as before but now the monitor will only say "monitor going to sleep" and nothing happens.
More likely to be bad capacitors (bulging top/seal) in the power supply, that will be the first palce to start, post back what you see inside so we can guide you further (it can also be bad inverter circuits, main power supply, etc), see example of failed Samsung monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums
If the CD drive door won't open, odds are that at least you know the drive is without power. Have you had the case opened up at all? With what you've described here your computer needs the tender, loving care of a technician.
First check the monitor sleep mode for your monitor in windows control panel, check that its not going into hibernation/stanby. if thats not it. and the monitor keeps shutting down. You may have to replace it newer models have more features and could be cheaper by saving you the hassel check newegg.com or orverstock.com
if nothing works and you cannot access your monitor settings via the menu button on the monitor then you have no way of correcting it. as far as i am aware the only thing you can change with the monitor from within your operating system are its resolution, refresh rate. so i think you need a knew monitor.
I think you have the display shut off. the button on the bottom left will shut screen off. It will come on for a few seconds if you touch the screen, but will shut off again. just push the display button again and it should stay on.
Your monitor has brightness and contrast controls either on the bottom or the right side. Sometimes you have to push the menu button and then scroll to the proper setting. If this is the case, there will be an "up" and a "down" button to use. Once you are in the correct menu, you will have to push the menu button or the enter button to activate the setting. This all depends on the monitor model.
