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 and will need to be replace.

I advice you replace the picture board on the screen of your monitor to solve the problem of the blank screen.

Take care.

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.

Even if the hard drive is bad you should still see the normal bios post screens and then an error message saying "no boot device found" or something similar. If you have a monitor in your home you should attach the vga cable from it onto the vga connection on that laptop. Then turn on the laptop and see if you get a picture on that monitor. If you do then either the laptop lcd inverter is bad or the lcd itself is bad. If you don't get a picture you may have to press a toggle button or buttons on the laptop to switch to the external lcd. Usually this is Fn plus another F button on the top.

Problem in Your monitor VGA cable no horizental or Vertical signal.So it is not active standby mode.Check signal or VGA cable on not adjust properly CPU.or any other device.May be VGA cable was broken.Replace it.If you are not replace the part so you can get help any service technician.

This sounds as if you are using the hibernate feature in windows reboot it and reset the power options to hibernate never check the vid connection as well

The flash light test only works with lcd monitor as they have back lights. Double check the connections again, also, if you can borrow a monitor try it on your pc, it may be your graphics driver needs to be uninstalled and re-installed, but you will need a monitor to see.
