screen is blank,it is image , not formed so blank screen if the camera is clicked no image is seen then it is the problem with the shutter,so replace the shutter unit.
Hi this is the way how to examine what's wrong with your LCD
monitors. Power on both CPU and monitor. After going blank, you
check that you can see the image on the screen by shining a flashlight into the
screen, not directly but find the best angle to the screen and take a look very
closely. If you can see the icons or any image, there will be a minor problem.
Like me, I can see window image using flashlight and check lamps inside. Some
of them were broken and it is easily replaced. If you cannot see anything on
the screen, there'll be some problems with inverter board. If you have
soldering tool and want to fix it by yourself, check the caps first. It may
cause this problem. Some caps might show leaking or burn spot on the board
because of too high temp. If you don't have soldering tool, you better go get a
technician to do so.
Ok, from the beginning. Can you do a cold boot and get into the bios? (is there an image on the screen then)
Secondly, can you connect to an external monitor and see an image?
Did it do this only when it was heading in to hibernation? If so, it sounds like the power management needs some adjustment.
If there's no image on the external monitor, you may have a video/motherboard problem, or it still could be the operating system/power management.
It all depends on if you have video in bios.
Let me know.
Good luck
