My right side of the display haves lines. What should I do?

I have my Mac Book Pro since September 10, 2009. Yesterday I pull it up from the right side of the Display, and it started to show green and other colors lines flashing on the right side. Picture: http://yfrog.com/gzed6oh . This lines sometimes appears and sometimes doesn't. It depends on the angle the display is.

I don't have any warranty. I want to know what it is so I can make a decision. Obviously I want to fix it, because everything else is working well. I will appreciate your help.

Sorry if my English is not good. It is my second language.

this should be you lcd also. try first with lcd cable. check the lines are permanent or temporarily. if temp means lines comes when you are changing the display lid postion the lines become more or less or sometime no lines. then its you lcd cable. if lines are permanent no fluctuation in lcd the probably you lcd is bad. check it. removing glass from display is little hard best of luck


First when I posted the question the lines appeared depending the angle of the display; it appeared and disappeared but now it doesn't change it is always appearing. How much time can I be with this problem after it continues spreading tru all the lcd?

It sounds like the cable from the logic board to the LCD. To be sure you should hook up to an external monitor and see if you have the same problem. While you are checking this out please tell us the last three digits of your serial number so we may accurately recommend the correct part.

The last 3 digits from my serial number are: 66D . I will be looking for a external monitor to see if it haves the same problem and will be telling you.



I just tested with a external monitor and looks perfects. No lines. What do you recommend me?


You probably need to replace your display data cable--link provided. Note this is a very difficult repair so read the instructions carefully before you decide to do it. Unfortunately ifixit does not carry the part. You need the display data cable. Check with Powerbook Medic or Welove Macs for the part. Good luck.
