Hi everybody, This is my first post on what appears to be a great site. Any advice will be appreciated.
Here goes: I have a tibook onyx 550. Like new. I put a new 5200rpm 120gig HDD in it a couple months back and maxed the ram at 1g and did an open firmware install of Leopard. It has been running great for a couple months until recently when I began to have display distortion. I've reset the PMU and PRAM, no luck(neg), EVEN went back and reinstalled the original OSX 1 that came with the ti, again neg. The display issues got worse and worse until now, I get a startup chime and a gray backlit screen. Obviously nothing is getting to the display but a backlight. I hooked it up to an external mon and it works fine. Any ideas short of replacing my laptop?

any issues with the hinges? If the hinges have gotten wobbly they could have easily cut through the display cable.
