hey guys, this is my first post on this forum so please be gentle with me until I figure out this site better. My problem is, I got a G4 15" powerbook 1 ghz model a1046 off ebay for cheap untested. I charged the battery and turned it on and got this http://www.youtube.com/watch?v=Dle5U-_nfW4 . I did some other basic deep reset by taking out battery pressing power button a few times and leaving it for awhile but nothing changed. tried to power it without battery but nothing booted. I put in a cd in drive it spinned but nothing changed. I moved the screen back and forth and at different angles and nothing changed is it beyond repair?
