After getting my K750i my screen broke. I brought a new one and installed it acording to instructions. However my screen's back light will not turn on yet the keyboard will. If I press down on my screen however it will momenterally turn on. Any help would be appriciated. I am not sure if it is my installation or the screen that is faulty!

Try to return the lcd you bought and have the service crew install it...faulty merchandise usually gets blamed onto customer's if improper instalation.

I brought my phone out side and went running but when I came back in the screen went black but the phone still is working it just wont let me see the screen


Sounds like the back light is out. Most cell phones dont have seperate back lights. You can order a new screen for it but it takes special tools to install it.

Oevrall screen is black


First off where did you buy the replacement screen? Second did that screen also come with new ribbon cables?

If you bought the replacement online and just installed it without reading the instructions or it didn't come with any then you have the reason there.

If you did read the instructions and followed the steps correctly, then did the replacement come with new ribbon cables and connect lines is the next part, because the reason the first screen failed was not only the screens dynamics, but the constant open and closing, bending causes the cables to get worn in the same area and eventually it will tear or just break. And since you stated that the hinges had broke first that automatically says that the screen will fail due to not being able to function as it should. So with that said, and your answer was YES to the new cables, then final step is to retrace your steps when installing. Because you forgot to reconnect something to have the screen light up. If the white light on the screen doesn't light up you will see what you see now.

I suggest you to goto ifixit.com they have a step by step with images to install or replace parts on all Apple portables. Just follow their instructions correctly to find your PowerBook and then use their install steps.
