My computer monitor will only stay on for about 10 seconds and then goes off. If I turn it off and turn it on it comes on again for seconds and then shuts off. If it's not plugged into the computer I can see the floating box indicating that it's not connected but then it goes off. I can't get to the settings because it shuts off before I can see the settings. The power light stays on throughout. If there is not a computer connected to it the power light turns amber.

There is likely a fault with the computers graphics card or memory.

The screen will not display that box when the contact loop isn't completed (ie connected to a undamaged port)
if there is no signal being produced from the graphics card / the system then it won't display and go into stand by mode.

If you know how to

- First ensure the system memory is fitted correctly
- If there is an AGP / PCI / PCI-E graphics card make sure this is also seated properly

If possible test the pair in a known working machine - if they work, it's likely your processor
If one doesn't work then it's more than likely to be the cause.

hope this helps

Kind regards
James

Thanks, good thought. I've tried it on several machines now that other displays work on.

It doesn't work even if I put it on another machine.

Hi there,

in this unlikely situation it's the monitor or the cable, try replacing the cable if this doesn't work on a known working machine then the signal processor has died in the monitor and knowing dells it'll be cheaper and easier to replace the monitor than the signal processor

Kind regards
James

Okay. Thanks. I changed the cords and I got the same problem. I'll have to let it go. Thanks for saving me the time.
