LCD Screen flickering/jumping. Screen jumping across?

I have purchased a second hand Macbook and opened it to find the screen flickering, but rather than flickering off and on it flicks the image to the left, for example my Macintosh HD icon which is in the topright of the my desktop flickers to top centre and if a dialogue box is open that also flickers across the screen.

This doesn't happen if i am typing in a dialogue box so thought it might be as simple as a sticky key however if you just press keys when sitting on the desktop it still happens.

Has anybody had experience of this problem before?

I have just discovered if i select the display to be 256 colours rather than Thousands, or Millions, the flicker goes away.

Does anyone know what this is pointing to in terms of a fault?

Have you discovered if it does this on an external monitor in the thousands or millions of colors, yet?

Does flexing the screen back and forth have any effect? I would guess the video cable is somewhat loose, either on the back of the screen, or on the logic board (the fact that it happens when you type may indicate it's the logic board end).

First I would connect to an external display and confirm that the problem is NOT evident externally...confirmation of that tells you the problem has to do with your internal video display hardware (screen, cabling, etc.) If the problem is mirrored on the external display, that means it's the board or the video chip, but I suspect that is unlikely in this case.

Assuming the external display looks fine, I'd take off the topcase and re-seat the video connector. If that doesn't help, I'd take out the screen and re-seat the video connector on that end.

I wouldn't really suspect the OS, but to rule that out you could always boot from an external drive. If it has the same problem, you know it's not the OS, and if it doesn't have the same problem, you know it is the OS, and you can resolve it by wiping the drive and restoring (but, again, I don't think that's the issue -- sounds like hardware).

Thanks for this- flexing makes no effect. I forgot to mention i dont think its the connections as i replaced the data display cable thinking this would be the problem however the problem is identical. Havent tried an external display so will try that next and also try rebooting from an external drive.

Thanks!
