Q: Black screen iMac ( 27inch - mid 2011)

Hello,

 

A friend of mine has problems with his iMac (OS X Yosemite 10.10.2).

He regularly will see a black screen before or after login. Only a black screen, no black screen with a mouse pointer.

Sometimes he will see several black screens a day, and sometimes nothing happens several days.

What we have tried:
Resetting PRAM and NVRAM

Without success, unfortunately. Black screens are still there.

I hope you can help me and my friend.

Thank you.

iMac, OS X Yosemite (10.10.2)

    Thanks for the heads up on the read out of things...

    Im still getting the screen to go black but its very random

    I will in the near future replace my 128 gig ssd for a much bigger ssd but i have some working coming up that needs doing first.

    And the thing to do with the battery on the logic board is that the reason my screen is going black ?

    I have reset my NVRAM & PRAM. and get the black screen are well.

    regards

    andy
