Problems And Solutions When Your Screen Won't Turn On

You turn on your computer and go get a cup of coffee. When you come back, you hear the computer running, but are staring at a blank screen. Oh, no!

There are many reasons why a computer screen just won't turn on all of a sudden. The important thing is to relax and analyze the potential cause of the problem in a calm manner. Many people start to panic thinking that their computer is gone for good. Whatever you do, do not open up the monitor to inspect the problem yourself. The cause of the problem might be something far simpler. Also, a computer screen has intricately assembled parts that should only be handled by experienced technicians. Let's take a look at some of the common problems you can run into.

Loose cables - Most of the cases of computer screen problems arise out of loose cables. The VGA cables that are connected to the computer and the monitor will usually have a couple of screws that will securely hold it in place. Over time, they might come loose and the pins might have loosened enough to make the monitor go blank. Check the cables and tighten up the screws if you have to. It sounds simple, but it works.

Power to the monitor - The surge protector or the UPS that you monitor is connected to might have failed or short circuited. You can check this out by plugging your monitor or your computer straight in to a wall socket. If it works, you will know that you have to replace your UPS or your surge protector.

Check with another computer - Most households have a couple of computers. Take the monitor that is not functioning to a computer that is functioning well. Substitute the working monitor with yours and see if it works. If it doesn't work, there is a good chance that your computer screen needs fixing. If it works, it could just be a problem with the video card on your computer. You can use the next step to look into that.

Checking the video card - A loose video card in your computer can also result in a blank screen. Turn off your computer entirely and remove the protective cabinet cover. Pull out the video card and reinsert it to make sure that it is securely in place. Put the cabinet back in place and try connecting your monitor to see if it will work. If it works, the loose video card was the culprit responsible for your blank monitor.

The above checks and solutions will most probably be enough to fix your computer screen problems. If not, you might have to take your screen to a repair technician to have it looked at.
