Hi all,

 

I have a 2010 Macbook Pro 13" running OSX 10.8.2.

 

In the last 24hrs or so it has begun acting very strangely. The screen has been blacking out when the computer is lifted off a surface or tilted backward to sit on it's spine. At first, it was just when it was moved to put pressure on the back left hand corner, but now it will black out when it is nudged and even with no movement at all. Additionally, the screen now not only 'blacks out' (mind you, it still appears to be backlit), but it will also black out to a specific colour. So far, my screen has been completely filled with bright pink, and then green, on two separate startups. I have had to do a forced shutdown when this happens as it becomes completely unresponsive. If I try and reboot too soon after forcing shutdown, I get intermittent beeps that are synchronised with the light on the front right hand side. When this happens, I get no Apple chime, no response from the keyboard, nothing. Have to force shutdown again and wait for a while. The beeps seem to be one to every five seconds.

 

My first thought was RAM or the display cable, but after replacing the custom RAM with the original RAM I got with this computer, the only difference I found was that the beeping at startup stopped with one of the custom chips out. The screen issues persist.

 

Moving the display angle of the Macbook Pro does nothing to return the display. Keyboard stops functioning. I've tried booting into Recovery, but often this hasn't worked. I've reset PRAM and SMC but have not noticed any difference.

 

Any ideas would be much appreciated
