Problem with display / screen image

Texte:

When booting up, more often than not the screen is just fuzzy grey with a few vertical lines here and there which dance about. Sometimes the screen is dark with no image. Holding the PB partially open with the hinge end pointing towards the floor will sometimes get a good picture on screen and gentle handling will keep the picture and the PB is usable.

Does anyone have any idea if this is fixable or if it's more likely to be the video chip? I'd love to get it working again and am quite happy to take it apart.

Thanks.

Edit:

I have got hold of a mini-DVI to VGA cable and tried to connect to an external monitor (Asus 19" Widescreen) but get nothing. I have tried closing the lid as soon as I press the power button; pressing the Fn and F7 keys; and disconnecting the screen cable so only the external monitor is connected.

The strange thing is, if I wait until the PB has finished booting up, I can press the power button and then Enter and it shuts down just as it should.

I would love to get this working but I fear the worst. Your comments and suggestions are appreciated.
