Monitor switches off!

Well, a driver is not required to use the internal speakers! You just have to plug the OUTPUT from your computer sound card into the input jack on the rear of the monitor. For this, of course, you will require a suitable lead (or cable) with stereo jack plugs on each end. The sound output from the speakers is only 1 watt so don't expect wonders..but it does have a headphone socket so it would make a convenient point for you to plug your headphones to, but of course, you've got to feed the output from your sound card to the monitor first.

You need to determine if you is turning off or going into standby mode. When your monitor shuts off, the power light will turn orange if it is in standby or the light will turn completely off if the monitor turns off. If your monitor goes to standby, that means that your monitor is losing signal which indicates a problem with your PC. #1 Make sure cable is firmly secured and both screws are tight #2 Check your video card make sure that it is firmly in its slot. Take it out and put it back in. *as long as your computer is open give it a good cleaning with compressed air* If those things check out it is possible that your video card has failed and needs to be replaced.
If your monitor is powering off #1Check plugins- try something else (i.e. lamp) in the outlet #2 Try your PC's power cord in your monitor

1) No. The switch color should have been Green

2) No Signal on the monitor, indicates the monitor is not receiving a Video Signal from the computer.

A) Could be due to a faulty monitor cable.
Monitor cable is used on a working computer for a test,
Or,
working computer's monitor cable is used on the Advent for a test.

B) Could be due to the graphics 'engine' on the motherboard, or on the graphics card is bad.

[Graphics 'engine'.
GPU
Graphics Processing Unit.

http://en.wikipedia.org/wiki/GPU ]

If the computer is using Integrated Graphics, the GPU is on the motherboard.

(Integrated Graphics is also referred to as OnBoard Graphics. Meaning On the motherBoard)

You will know if it's Integrated Graphics, because the monitor cable will be plugged into the VGA connector, on the motherboard

http://en.wikipedia.org/wiki/VGA_connector

Since you indicate an adapter was included, to adapt to a different port (Connector), it could be a VGA to DVI adapter, or a DVI to VGA adapter.

Your monitor may just have a VGA connector on the monitor cable.
Hence you would use a female VGA to Male DVI adapter.

Your monitor may be an LCD flat screen monitor, and has a DVI connector on the monitor cable.
Hence you would use a female DVI to Male VGA adapter.

DVI
Digital Visual Interface

http://en.wikipedia.org/wiki/Digital_Visual_Interface

VGA monitors are Analog.
LCD monitors are Digital.

A computer puts out a digital signal.

If a VGA monitor is used, the computer has to alter the Digital signal to an Analog one.
This slows down the video signal.

If your monitor (In any case. Not just this one), is an LCD flat screen monitor, it is best to use a DVI monitor cable, and plug into a DVI port on the computer, if available.

If your monitor is a VGA (CRT. Cathode Ray Tube), monitor, and you have a DVI connection on your computer, using the adapter will do you no good.

The adapter just uses the contact pins for VGA, that are present in that DVI adapter, and hence the DVI connection on the computer.

You're still just getting an Analog VGA signal.

Example of a female VGA to male DVI adapter,

If the Integrated Graphics are suspected to be bad, a graphics card is used in the appropriate expansion slot, for a test.

If the graphics work then, the graphics card is left in service.

After I test the monitor cable my next procedure is to suspect the Power On switch, or the Power Supply, and go to the graphics next.

The reasoning is that Power Supply failure, is the number one cause of computer failure.
The next is the Power On switch, then Electrolytic Capacitors used on the motherboard.

(Specifically, any Electrolytic Capacitors used in the motherboard Voltage Regulator Circuit)

If the Power On switch is bypassed, the diagnosis will reveal if the problem is the switch, or Power Supply.

Bypass the Power On switch, and the Power Supply comes on?
Problem is the Power On switch.

[One Power On switch I have found to fit a lot of computers. The Power On switch goes into the plastic Power On button,

http://www.directron.com/atxswitch.html ]

Bypass the Power On switch, and the Power Supply does Not come on?
The problem is the Power Supply.

The Power On switch is bypassed using a jumper wire, from the green Soft Power On wire, to ANY black Ground wire. The contact made is a brief momentary one.

The jumper wire is used at the back, of the 20, or 24-pin ATX main power cable connector.

Hi! Try to check if there is a hotkey to turn on/off lcd display. If none, try to power drain the machine by unplugging ac adapter and removing the battery.Press and hold the power button for 10 secs and then after that put the battery back and plug in ac adapter.Press power button and then check if you will see anything on the screen,if still the same then try to connect the laptop to a external monitor and then press FN+F5 to switch display to external monitor, if you see something on the ext monitor it means you are dealing with a faulty lcd on your laptop...Hope this helps...

Hi

Thank you for your query

The fault you are explaining can be either the monitor or possibly even the VGA card

To rule out one or the other please try try the following

1) Plug the monitor in another PC, if the monitor works fine then the VGA card may need to be replaced

2) If it still occurs then the monitor is at fault and wil need to be replaced/repaired

I hope this helps

The monitor requires a adapter with a current output of 4 amps. but the Western Digital Book adapter can only supply 2 amps (half the current required by the monitor).
This means using the WD adapter on the monitor will stress this adapter beyond its capacity and continual use of this adapter on the monitor will cause it to fail and/or switch off if it has overload protection.
If you are having problems with the 2 amp adapter on the WD Book, then the power adapter could be faulty or it maybe OK when the adapter cools down.
I suggest you get a 12 volt 4 or more amps adapter for the monitor.
You may need an adapter for the WB book too if the adapter is faulty.

are you using a Mac Mini-DVI to DVI adapter or any adapters? This is a VGA video output type of KVM switch so probably the problem is with the adapters involved to it.

Well, suddenly it worked again. But I waited the whole day >.>

This type of problem is so common nowadays. What I did is open up the casing, pulled out the RAM and by using pencil eraser, rubbed the contact pattern. Put it back and turn on your computer. Always work for me and hope it might work for you too.

Try another power adaptor. Check the delivered voltage and go get a universal power adaptor that has a switched for varios voltages and a number of connectors. Simply match connector to the voltage switch.
