Please make sure that the cables are all securely plugged into the back of the monitor, and into the back of the computer. Also make sure that there is nothing that was recently placed near your monitor (or your monitor's cables) that can cause interference.
If this does not fix your problem, try connecting your monitor onto another computer to see if it works there. If it still does not work, even when connected to another computer, it is possible that your monitor cable is faulty, or the monitor itself is faulty. I recommend taking your monitor and it's cables to a computer repair shop for further repairs. If it works on another computer, but not yours, then it is possible that
your graphics card or computer may be the cause of the problem. Open the side panel of the computer and make sure your graphics card is securely plugged into it's slot. If this does not fix the problem, I recommend taking your computer in to a computer repair shop for further repairs.
The picture board on your monitor is bad, since the power led or button is on and all connection are corrrect, it means the
board of your monitor has developed fault.
The best thing for you
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
go to the add a--- section under the control panel and right click on the monitor/s
click on the properties tab and then click on the compatibility tab
tick the box and click on the os you want for that computer
click apply and ok
in that properties you will also find a drivers tab , click on that and then the driver update line
it will search and download the latest drivers or come back with a message that the driver in use is the most appropriate one
I would suggest Tritronics for the service manual and the replacement parts.
Unless you have a service manual, it takes a lot of disassembly by careful observation (or trial and error) to determine how that delicate LCD panel is put together!
Of course I'd want to be sure that the problem is not in the inverter instead since that's a much more common cause of backlight trouble.
Unless you happen to know it's one or more CCFLs, then of course you'd want to replace them all since they have the same aging.
Are you using the digital connection??
If so try using both the analog and digital connection then set the digital as the Main monitor in your graphics card interface.
To check if the backlight is out, darken the room, and light a flash light into the screen. If you can see a picture, then you need to replace the backlight.
