So it started a few weeks ago if I would leave my Laptop on and comeback the screen would remain black after returning from standby. Simple fix reboot and screen comes back.

Today the screen went blank and will not come back. OS, sound everything works during boot up. If I shake my screen I can get it to come on for a second or two. I got the screen to come back one time but it was very very very dark.

So I want to get to the LCD cables that connect to the MB and check those I cannot find any online how to guides.

There are so many screws and I just want to access the one part of the LCD connection so if anyone knows a quick way please tell me.

Please help if anyone has had this issue.

Picture shows up on an external.

I reseated the cables no luck the screen went bad I take it.

If I order a new screen does it come with a inverter or is that a seperate part I have to order?

Upodate.

After everything was reseated the backlight is totally burned out.
