Hi, my friend just gave me his old g4 after buying a new mac. I am having the grey screen issue. I know nothing about macs and have been reading about this issue, but no luck so far. I am fairly sure it is a screen issue because my fiend was able to transfer info from the g4 hard drive to his new mac at the mac store. Also, the keyboard is responsive, i can change brightness, change volume, and the screen dims after it has been idle for a while, but brightens when i touch the pad/keyboard. Any info or cheap fix ideas would be greatly appreciated, sorry for the long winded post, thanks in advance.
