PowerBook boots to a grey screen when HDD connected
Just repaired this PB, which was missing parts when I bought it as a scrapper. I had the bits it needed so I brought it back from the grave. When I booted I got grey screen so I swapped out the drive for another but got the same result. Both drives function when mounted in a caddy so I assume that the fault is not with them. To check if it was a board problem I booted without the HDD but with OSX disc in the optical drive. The machine then booted perfectly normally, read the disc and proceeded to installation until requesting the destination, which of course was not there. As well as trying two different HDD I've tried three different ribbons and always get the same result, start up chime and a grey screen.
Anybody come across this scenario before??
All help most welcome
