I have owned my powerbook for about 2 years now and this started happening a few months ago. It has gotten progressivly worse. (see picture)
Lines change a bit when screen is moved on it's hinges , but not that much. Restarting used to get rid of the lines but that has not been working lately. Usually the display is fine at first but when I walk away and the screensaver kicks on the lines start up.
People have told me it is the display, others have told me it's the logic board...whatever it is, it stinks. I need this computer to hold out for at least 2 more months while I finish my senior thesis, but it's fading fast. Any suggestions/reccomendations would be greatly appreciated.
