try orther monitor yet?
power getting to monitor?

Hello
That is a video device problem.First you need to check you monitor cable,it runs from the monitor into the back of the pc into your video device.
Hopefully you have a video card,but check that the cable is secure and tight.You may want to remove it and put it back on just to be sure.

If this doesnt help try restarting the pc and hold the f8 key down and select safe mode.If you get a picture on your monitor you may need to reinstalll the video drivers.If not then you have a bad video card or a bad video chip depending on what is in your pc.

Try your monitor on another machine - if it is working you have operating system/hard drive/motherboard/memory/heating problems. You must work that out if the monitor is good.

Check you rmnitor data cable from CPU its not connected

ok sounds like you have a broken pin on your cable if you look in the end of the cable plug the part thet goes into the box but also check both ends if they are there
failing that take monitor to roof and heave ho away it goes

HI,
You should connect the monitor to the graphic card.

You may need to replace the moniter cord or check the video card on the computer.

Hi
First thing, change the cable and use a digital cable, Power everything off, disconnect the power from the moniter and the pc, leave it for 2-5min and then connect them back again.

Let me know what happens

Take the post (power on self test) disconnect vga cable and connect power cable if monitor shows no signal check signal cable massage then monitor is ok fault is in cpu. open it and clean the dust
by vaccum cleaner you will get the display again
