Hey guys,

My laptop screen misteriously started going black a few days ago. When that happens, the screen goes really dark, I can still see some window lines if I really put effort, but it is so black that I can not read anything or see where the mouse is. To remove this black screen I figured 2 ways: Either restarting my computer or closing my laptop and opening the laptop again (which makes it hibernate). Once the light is back on the monitor, all the white colors seem very pinkish for a while, then it goes away. After a minute or two, I will get the same black screen. I assume there is maybe a lightbulb or something like that in my laptop that is not working well... Anyone can help me??

Thanks in advance!

Note: About how long it takes for my screen to go black, it is purely random, I have tried to see if it was when i moved a winow, opened a program, even timed how long it takes to go black, and didnt see any pattern, it could be 1 min or 1 hour before it goes black, although, lately it is more like under 10 mins...

It's either the backlight itself or the electronic inverter powering the backlight that is failing.

In some models, the backlight is part of the screen itself, but in any case it's not a DIY unless you have the service manual, access to spares and good microsurgery skills.

It's a "backlight", and yes, it's either the backlight or the inverter.
On some laptops you have to change the whole LCD panel for the backlight.

Just getting it apart without cauing permanent damage is a problem, unless you have the tools, service manuals and experience.
