LED light on the computer monitor is green, but does not display anything.? | |
Friend of mines has a computer problem. She usually has her computer on and it hasn't been having a problem, but after shutting her computer down and trying to power it back up this morning, the LED on the monitor is green, but it isn't displaying anything. There are 3 pins missing from the plug but it has been working fine before with those pins missing. Any suggestions would be helpful. Thank you
Answers:
1The video card might be fried. How old is the computer setup? Has any trauma occured to the computer lately? Ex lighting storms, being kicked or dropped, etc.
Green LED means that the monitor is receiving a somewhat usable signal, while yellow means that the video card isn't pumping anything out.
If you can, try hooking another monitor up to this computer and see if you can produce similar results. If so, it's an issue with the video card (or a deeper issue inside of the computer). If the second monitor produces video, then it's the monitor itself that has just finally gone bad.
If the video card is standalone (meaning that it's not built into the motherboard, you can also taking the paneling off of the computer itself and reseat the video card. Do this by pulling it out (remove any screws first) and pushing it securely back into where you pulled it out of (or, if there is room elsewhere, try sticking it into another slot of a similar type). Remember to screw the card back in.
If none of these work, run out to an electronics store, buy a cheapie video card, and throw that into the machine. If THAT doesn't work, then something's wrong further up the chain. If it does work, the elder video card is to blame.
Another avenue to think about: when you turn on the computer, can you hear the hard drive(s) loading up the operating system? Usually they make considerable noise if you're listening close to it. If so, you know that the computer is operating normally.
Sorry this is so scatterbrain, I just hammered it out as I thought of it. Good luck!
Edit: the three pins, as pointed at by some other answers above, don't really matter. Even if 13 pins were missing, you'd still get some random coloration. My monitor's missing 4 pins, three video cards later... and I still get a great picture.
