3 horizontal lines with black on bottom and loose lid, fix?

When opening the lid of laptop it makes a loose crackling sound and now horizontal lines with black on the bottom of screen. Before I could wiggle the screen and it would be ok, but now black won't go away. Any help would be appreciated.

I hooked up to tv and looks fine on tv. Computer screen however is weird. Black screen around and black on bottom. Does that tell you anything?


Your logic board seems to be OK so if you're lucky you will only have to replace the LVDS (video) cable or check the cable connection to the LCD panel and to the logic board. Be aware that the LCD panel could also be the culprit. These two parts must be tested to find the faulty one.


Thanks for the thoughts. I think I came up with a temporary fix for now. I just don't move or shut the lid. Put it to sleep manually and set aside till next use and she is working ok. Thanks again.

Please connect your PB to an external monitor and tell us if the video is normal or not. At first sight from your description there could be a problem with the LVDS cable or the LCD panel but to exclude the graphic processor failure we need a description of an external monitor view.

This is a known problem on this model of PowerBook. It happened to one of our household computers after we sold it to a friend, and the display had to be replaced (it got done by It may also be the video cables that run through the hinges, a pretty difficult fix.
