Hello,

I have a Sony SDM-P234 LCD monitor that has been stuck in power save mode for the past week. I remember that I was surfing the web like normal and out of nowhere my monitor suddenly went to a black screen with a message in the middle saying "No Input Signal. Input 3: DVI-D. Go to Power Save."(the screen goes blank shortly after displaying the message) The computer(Alienware, desktop, I have had for 3 years) is still running because I can hear it, but the light on the monitor has turned from green to orange. Pressing it will turn the light to red to turn it off. Pressing it again to turn it on, will cause the light to be green, but it will turn back orange again when the "No Input Signal" message leaves the screen. I get the same message from the monitor even when the computer is turned OFF. Nothing seems to boot at all - there is no POST beeps and I cannot get into the BIOS. I have tried:

- Restarting my computer. // many times
- Turning my monitor off and back on. // many times
- Unplugging and replugging DVI-D cable to computer. // many times
- Unplugging and replugging DVI-D cable to monitor (to the 3rd port which is a DVI port, not sure what the first two are).
- Restarting the power from the surge protector.
- Pressing random keys on my keyboard and clicking my mouse.
- Checked to make sure there are no bent pins on the DVI ports.
- Double-checked to make sure video card and RAM sticks are secured in place. The computer has never been dropped/kicked/etc.

(I encountered this same problem several months ago but solved it temporarily by pushing my monitor's power button off and back on. I also tried making sure it wouldn't happen again by completely disabling/turning off all my power settings in the Control Panel.)

I have received advice from friends that it could be a problem with my PSU but I was hoping to get this fixed without going through the trouble of hardware replacement. Any suggestions will be greatly appreciated, thank you!

sounds like your video card is going out or is already out.also if you have on board video try that first if so and that makes it work you need a new video card

Do you have video when first booting? If so, try booting into Windows Safe Mode (F8) at start up. Make necessary changes there.

If not then it is the monitor, the cable or the graphics card/chip.

Card may have died or possibly came partially out of the slot (not likely but possible). If you have two video out on the card/chip then try the other one.

If you have on board video and are currently using an add in card remove the card and try the on board.

I don't have another video card to use.. and I cannot boot into Safe Mode. I have tried hitting F8 repeatedly, but the monitor doesn't even display anything at all.

Did you hear beeps when booting the computer previously? Do you hear any now?

Yes, the computer makes the beeps back when it booted like normal. But ever since this problem started occurring last week, there are no beeps at all.

Then I would suspect a bad power supply as the first choice.

Try removing all the RAM and then booting. You should hear beeps then.
