Hello,

The picture board on your monitor is faulty or bad, since it goes black after few seconds, it means the picture board of your laptop has developed fault.

The best thing for you to do now is to take the laptop 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.

Hi my name is Rain.
Ok so that im clear on the problem. your monitor will come on but in a matter of seconds it goes to a black screen?
If this is the problem. The answers you seek will most likely
be in your video card.
Try this test:

• Unplug monitor from the computer.
• Turn on monitor .
• Look for monitor self test screen.

If you see the monitors self test screen then your problem indeed is
the video card . You will need to replace the video card inside of the computer.

Right click on your desktop go down list to properties and left click under the screensaver tab click the power tab and turn off the power saver in other words change settings to always on and no hibernation

u r too thick

Proceed with caution! High dangerous voltages exist within.
Check the current sense circuit from the aquadag coating.

Go to Start, Control Panel, Power Options and change your monitor setting to never turn off. If you do leave your monitor on all the time then you should set up a screen saver.

i have tried to fix these problem before but no good i did find a web site that will also stat that this can not be fixed but rather they will replace the lcd film at a not so bad price

ok,your monitor has a defective vertical ic.when vertical ic is defective you can see the horizontal line.
