White Screen, nothing else

Just got an old Macbook Pro from a friend which stated the screen was all white and nothing else but the chime.

Verified the white screen and nothing else but that. Tried to clear with CMD+P+R but didn't help, still only the chime (once) and randomly turning off the computer.

Opened it up, checked cables and everything looked OK.

Tried booting it up without the battery - the backlight on the keyboard started working, but nothing else.

Replaced the RAM-modules (2x2GB) with 2x4GB, same with the old harddrive, replaced it with a Samsung EVO 840 120GB.

Nothing...but the white screen.

Plugged in the Mavericks USB install whilst having the harddrive unplugged...after about 30-40 seconds I heard a voice which was familiar from the installation guide.

But the screen is still all white.

Any ideas why this is - and how to resolve it?

A white screen usually indicates a hard drive issue. I don't know what was on the Samsung drive. The first thing I would do is replace the Hard Drive/ IR cable with a new one.

The original drive which was installed when I got the Macbook, is an old Hitachi 320GB drive (manufacted february 2011).

Could a faulty HDD/IR cable really cause my problem? Seems kinda far fetched. :)


That's why I'm the Mac Professional and you're not. I now keep 6 of these in stock as the problem is so prevalent. See this question: Using new hard drive cable in older machines 821-1480-A


How can I see what kind of cable I need? I only have these numbers... Model NO: A1278 Serial NO: C2VFD1M4DH2G

Thanks alot for your help, I think I'll order one and see how it goes. But, I can't imagine a simple HDD cable can turn the screen white and make the computer turn off randomly...it just doesn't make sense.
