Power book g4 1ghz

Hey,

I have had my powerbook since 2003 and used it up to 2005. For some reason my logic board went out which got replaced by apple but up to this day…it still doesn’t work. it worked for about a week when i got it back from apple not to mention my os x 10.4 disc that was unreturned by them. To make a long story short I would like to resurect my powerbook….any ideas? I screen won’t come on but the power is on.
