Monitor turns itself off

Dell (E773p MPRII)
April 11, 2007 at 02:32:38
Specs: Windows XP, Dimension 8400 P4 1024MB

My monitor after pressing the on button comes on then 2 seconds later turns itself off and the green button flashes on and off. My computer is just over two years old so the warranty has run out. Any suggestions as to what is wrong? I used it at the weekend and it was fine - the next day it would not turn on again!

I had the same thing happen to a DELL CRT monitor after 3-4 years. It sounds like its shot.

Try the monitor on another computer or another monitor on this computer. It could be a problem with the monitor, the monitor connection, the display adapter, or something else inside the computer

If you plug it in on its own it works and comes up with an error message (can't remember what it says)

Disconnect the data cable from the PC and leave only the power connected, then turn the monitor on. If you get a display message such as "signal out of range" the monitor is fine and your problem is in the PC. Troubleshooting a non-booting PC has been described many times here.

I used to have a signature but it disappeared and I just couldn't be bothered writing another so please feel free to ingore this.

Something like data cable not connected. It amazing how much error messages help to determine what a problem might be.

Try plugging it into the computer with the computer turned off. If the message disappears then it's not the monitor. It is something inside the computer, probably the video card but could be almost anything preventing the video card from initialising.

Does the computer sound as if it is booting up. Disk drive lights flashing and sound from the speakers?

If possible you can remove any ? of your graphics card or something else having to do with your PC being the cause of this,a friend or neighbor that you know letting you swap out their CRT to your PC ,if the swapped out CRT works with out the same prob then you will know its your monitor thats on the blink ,you can also bring your CRT to someone elses place and have them hook it up to their PC se if it works !Just a couple of thoughts ,better then paying a$75 bucks to a repair tech to diagnos the prob ,you can find a used 17"or maybe 19" CRT for around $50 or less !
Good Luck Nick

Are there three buttons to the left of the power button on the monitor? If so, press the one on the far left and see if you then have a display.

Life is more painless for those who are brainless.

Monitor came up with "Check Signal Cable". This is OK seems my computer is no longer booting up and beeping three times (now that I have had a nose inside). Will look at answers from others then get brother-in-law to help as I don't know how to go beyond this.

Three beeps often indicates a problem with the video card. Try re-seating the video card as they can sometimes work lose.

Will it show in the manual where this is positioned? Is it connected to the motherboard?

The display adapter card will be where the monitor attached to the computer. It may be an integrated part of the MOBO.

OK - it is the video card (I believe) that is making the monitor not work. Took this out and connected it to monitor and monitor does not work. How do I find out what kind of video card I should buy? Is there a good website or should I play safe and go to the shops?
