Monitor goes black after boot up. I see the screen normally, then it goes black although the power light stays green

The monitor has failed, it is almost always cheaper to replace it than fix it.

I switch on my PC, ensuring that all cables, leads and power supplies are connected properly. The tower powers up no problems at all. I switch the screen on, the green led lights up, the screen is completely black. A blue box appears centrally on the screen with the text 'power saving mode'. The green led light turns amber and then the screen just goes black.

Please don't suggest going to control panel, as I can't get that far.

PLEASE PLEASE CAN ANYONE SUGGEST ANYTHING give me

your power supply board, probably has some bad caps in it

Replace your monitor power cord

try checking the cables first.

t certainly seems like the monitor is not getting a signal. Did this happen after you changed something, or just on normal boot up?
It could be the video card that has failed.
Also, check the pins on the connector; sometimes they can get pushed in.
If you can, try swapping out the video card or use the monitor on another computer.
Good luck,

it sounds like a deleted driver? try getting the driver for the monitor, did you loose the Operating system at some point, if so try a system restore to a date when the computer was working properlly prior to the malfunction. It sounds like it restored you to a time before the driver for that monitor was installed.

it is going into sleep mode, good luck with this.... i am currently asking how to get my hard drive to quite putting my monitor into sleep mode.

although it hasn't worked for me because my screen stays black, one of the options given to me is to try to start in safe mode and then adjust your settings to "never" on the energy/sleep/hibernate mode

some one else suggested that i remove and reseat the video card

hopefully one of those will work for you

"Most" newer monitors will let you know if the are no longer receiving a signal. Sounds like the backlight is burnt out. Try getting a bright (LED works best) flashlight and shining it at the screen at all angles to see if you can see any of what you were doing. If the backlight is on the fritz, either return it on warranty or buy a new one.
