Have you tried connecting this monitor to another computer?

Have you tried resetting the BIOS? That should reset any problem the video driver for the monitor maybe facing.

SOURCE: Benq FP71G LCD Monitor - Can't keep POWER ON / Button Problem?

I had the same problem and found that Q808, Q809 and Q805 had failed and which if left long enough can also cause PF801 to fail. I also replaced all of the electrolytic capacitors during the rebuild as it was only a few dollars to do so.

Although in my case Q815, Q816 and Q812 were fine I suspect that they may also fail in time.

Here are the parts which should be available at most electronic stores or online.

Q805 - IRFU9024N

SOURCE: Monitor goes blank , power light goes off.

Click start, then then control panel and click on the power management icon. When you see the screen, look at the power management "scheme" and pick the appropriate setting. I assume that what you are experiencing is what's known as "Power management" . In order to achieve an "Energy Star" rating, the computer must shut off various components to conserve power. If you don't want to have your monitor shut down, select never from the options in the Power Management screen. Thanks for using

Cant find driver for lg flatron 295lm monitor it keeps disconecting from my computer


OK, a monitor usually does not need any drivers to be installed. Hence, if the screen keeps disconnecting you might want to have a look at the connecting point between the monitor and your computer and the power connection.

Try different VGA cables and power cables, let me know if the problem persists, so we can try something else.

Kind regards

Monitor is not showing the display after booting.


Yes you have change the settings of your display to a higher resolution and your monitor is not compatible with that setting, to fix this you can bring your system unit to a friend or neighbor who has a computer and try changing it if your friends monitor is capable or compatible with your display settings. Or if you have other monitor you can swap it.

Hope I was able to help.

My computer cant turn on and its making noises

Did you your CPU Fan inside, that's the one who make some noises inside.
If your computer is failing to start then check CPU inside, all the peripherals double check on it. From VGA Card, Memory and other devices, maybe its not properly connected inside. Good luck!

Have a lg l1510s monitor and the power green ligt

Have you tried to substitute a different cable? Many times a cable can go bad, and you cannot tell, because of how they are made. Get a different cable to try as a replacement, and see if that doesn't resolve this issue.

Monitor problem

Your request for the exact problem will require a signal injector and use of an oscilloscope or even more test equipment. One possible cause is the contrast set to minimum.
