PB3400 - display is offset
Posted by: AlpineRaven on 2017-12-10 03:04:02
Good evening all, 
I've just obtained PowerBook 3400 for parts (good board but housing is very poor condition)- really I was after the logic board itself and I got a bit concerned.

Down the bottom of the screen about 12mm is black, the whole screen is shifted up hence no menu bar - see attached photos.

I've plugged PowerBook 3400 into external display - didn't even show any abnormality - as it showed normal, which leads me to believe the LCD screen panel is defective?

I'm trying to work out where the problem is - there is a board inside in the middle of the display I know there are caps - can caps cause that? Is it ribbon flex cable at fault?

Photo 1 - Mac OS starting up - see bottom of the screen is black gap approx 12mm... You can just see the mouse cursor.

Photo 2 - Menu bar cannot be seen but clicked Apple Menu and it'll show... just almost cut off "About this Computer"

Any ideas?
Cheers

Weird, can be plastic screen surround not original ? or the screen not fitted properly in the casing ?

I had this kind of trouble with a 5300, but the 3400 has only a 12 inches screen for all models.

resolution settings that are not suggested for the main screen can be applied and cause this.  Try setting to a different resolution.
