Why is my LCD display has some blue lights when it moves?

Thank you very much for answering,

it is a 2 GHz Core 2 Duo (mid 2007) A1181.

I lend it to a friend of mine and he slept watching a movie and I think that the macbook got too hot.

It might be a cable as it is just happen when I move it... but witch one??

Thanks a lot,

Yedo

Please un-accept my answer. By accepting an answer, no one else will attempt to help you. After your problem is solved, then accept the one that helped you the most. I'd still like to know what happens on an external monitor.

I'll check it tomorrow, I do not have a monitor here.

Thanks for the tip, I am new here and was wondering what does the accepting an answer meant.

Thanks

I see you un-accepted my answer as requested. If an answer helps you, you can give it an upvote (the arrows above the icon of the answer giver). If the eventual answer leads to solving your problem you can also accept it. After that's done, most of the time there will be no further comments on that question. It gets archived and when someone searches for the same problem, your question comes up. The points received are then added to the total of the answer giver. This in turn tells the community how much credence has been given to this answer giver. Points are also given for people completing guides. Most of the answers come from unpaid volunteers and most of the guides are done by iFixit employees. There is some crossover. When your click on users at the top of the page, these contributors are listed in order of point standing in the community. The people with are sepia colored photos are generally iFixit employees.

Just because someone doesn't have a lot of points doesn't mean they don't know their stuff. They may not have been around for a long time or their field of specialty doesn't get many question. So click on their icon and review their stats.
