Have you moved it recently? The monitor has a sensor that tells when the computer is on. Some times the computer settings tell the system to go in to standby mode and this will remove the signal that tells your monitor to stay on. Check your computer to see if it's running. Usually a green or yellow light on the machine will blink. If everything is good, check the pins in the cable from the CPU to the monitor. Check both sides. If a pin is bent or bad. replace the cable. Trying to straighten it might break off in the plug. Also, the video part of your computer may be bad. Try the monitor on a diffrent computer to see if it powers up.

My comuter w0n't stay on


o.k. unfortunately this may mean your monitor is in need of a service repair technician. The same thing happened to my hanspree monitor. Lucky for me mine was still under warranty. How about yours? how old is it? If it is not over 2 years old you may still have a warranty on it. please also try this: --------------------------------------------------------------------------------------------- so, it automatically shuts down? try turning on your pc and do not wait for it to boot to windows. instead, immediately tap on F8 key several times as soon as you see that there is power. it should lead you to Windows advanced options menu, highlight disable automatic restart on system failure using your down arrow keys then press enter. it should start normally or if problem still persists, try safe mode instead. it would isolate the issue. if in safemode it will still shutdown automatically then you need to replace your harddrive. if not, then you should just reinstall your operating system to have your system work fine.

I have an HP flatscreen monitor that worked great til the other day. Now it only stays on for about a second and then goes black. If I turn it off and then back on it again will only stay on for a...


i,m guessing that what has happened to your monitor is that there are caps (capasitors ) in a few of the monitors on the market today the company bought caps from capxon which is a bad company.... i see a lot of them in all types of systems anyway when the cap fails the screan fails most people throw the monitor away but the cost to fix it your self is about 1.25 cents
just open the monitor up unpluged of course
look for the cap that is not flat on top or has brown coming out of the bottom write the number down
( looks like 1000uf at 16volts ) example go to radio shack and get a new one soldering is not hard just be careful and put the new one in the same way as the old one ( remember + & - do count

Monitor displays breifly then goes to blank screen


If tried the monitor on two other computers with the same result -- definitly your monitor is faulty. Take it to the repair shop. To make double sure, run your computer with another monitor. If everything is fine now; you can blame the monitor.

HP a400n monitors


Sure but you shouldn't need to tell the computer what type of monitor it is, windows should simply send the signal to the monitor and poof up comes your display, more advanced versions may auto-detect or youc an select it in the control panel under display. Try craigslist to pick up a cheap monitor in your area. I got a 15'' flat for 20 bucks.

Samsung monitor


Try to plug the monitor into another computer and see if the problem reappears.

If the problem reappears - you have a monitor failure...if not, try checking the monitor connection at the computer side for bent pins or loose video card in your computer and test again.

Lastly, make sure your computer is not coming out of hibernation power mode (control panel, power settings etc).

Hope this helps!
