Try to separate the power cord of your monitor from your system or maybe if your using UPS(uninterrupted power supply) directly plug the UPS to the wall outlet. either you can use pretty voltage regulator to the regulate the AC power.
if not solve the problem try to examine the your system power supply.

How to fi a phillips 20fp shuts off in 2 scs.


Here's some tricks I would try...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your monitor on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.
Good luck.

this works for Dell monitors with a similar problem: shut down, turn off monitor and pc, turn off at wall socket, and remove power plugs from wall socket. wait about 30 seconds. plug back in, turn on, and all should be well? I have used this 3 times on a Dell PC with a Viewsonic monitor.

Make sure the plug from the monitor to computer is plugged in securely. Then, if the problem continues, replace it. It's on it's way out.

Here are the service manual (not usre which model you have, downloads are limit to two per day):

You need to do some voltage checking make sure you do have 5 and 12v. The caps the secondary DC side should all be replaced at the same time, it may look OK but they can have high ESR, and they also should be low ESR type such as FM or FC series by PANASONIC.

Monitor just turns itself off after 2 sec.


disconnect all the cables except the power cable and then turn the monitor on you would see a test screen if it still happens your monitor is faulty and better buy a new one as repairing is usually expensive .

Monitor turns itself off


hi, you must have enabled power saving options. Thats why your monitor shut down. you can disable, just do the same:

1.Right click on desktop
2.Select properties.
3.Select "ScreenSaver".
4.Select "Power" under Monitor power option.
5.There select "never" from Turn off monitor (drop down menu).

Now your monitor will not turn off automatically.

2 pcs - 1000 microF - 25v
1 pc - 2200 microF - 25v

Resolder the 2 transformer legs for the inverter.

Hmm... is still not working


Start your computer and tap the F8 key as soon as the computer begins to power-up. Keep tapping until you come to the Safe Mode screen. When the screen alerts you to the fact that you have chosen Safe Mode, click OK.

When you get to the desktop go to the control panel and launch System Properties. Go to Hardware and Device manager. Click the arrow next to the Display Adapter. Point at the adapter, right click and chooser Properties. Click the Driver Tab. Roll back the video driver to previous driver.

If indeed you have installed a new driver that is not compatible with your video card, then rolling it back to the original may very well take care of this problem.

Good luck!

Look up the BenQ website. http://www.benq.com/support/
These monitors have a 3 year warranty in most cases.

Failing that cantact BenQ directly with the phone numbers on that same site.
