Title:

MBP does not boot despite the chime and white screen

Text:

I try to fix a macbook pro A1278 2.4GHz. When starting it you can hear the chime, the screen gets white/grey. Nothing else happens. You have to push the start button for 5 seconds if you want to switch it off.

The keys do not cause any reaction. Except the start button.

What i have been trying until now:

* Several resets, pram and so on
* safe mode
* single mode
* verbose mode
* changed the ram
* changed the HDD Lion and Sow L
* target mode
* recovery mode
* dvd-boot
* aht-boot
* pushing trackpad-button to eject the dvd
* external keyboard / mouse

Nothing happens. But there is the chime and the bright screen. Has anybody got any idea? That would be great.

Device:

MacBook Pro
