Hello,

The picture board on your monitor is bad, since it goes off after few seconds and the power led or button is on, it means the picture board of your monitor has developed fault.

The best thing for you to do now is to take the monitor to a local repairer or service center within your vicinity to help with the replacement of the picture board because the fault is not something you can fix yourself, in order not to complicate issues.

Take care.

Hello,

The picture board on your monitor has been malfunctioning for quite the period but you did not notice it, since the screen goes blank, it means the picture board of your monitor has developed fault and will need to be replaced.

The best thing for you to do now is to take the monitor to a local repairer within your vicinity to help with the replacement of the picture board because the fault is not something you can fix yourself, in order not to complicate issues.

Take care.

Try the monitor on another computer that you know works, If it works on another computer then that means you have no video output on the original computer and you'll need to reseat the memory on that computer.

If you get the same response on another computer, then that means the monitor is bad and you'll need to replace it.

Try to do this: Just before the Windows start up screen (after the bios loading) press F8 and log in at safe mode settings. If at this mode you can see your screen change the resolution settings at a lower set. Save and reboot normally. Now try step by step to increase your resolution. In case of a blank screen appears at a new setting, don't do anything; after some seconds the monitor will come back to the previous settings. Save and go on.

In case of a problem or clarification, don't hesitate to post.

Thanks and regards

returning to Blackout mode.
• While the backlighting is turned off, the function indicator
