Screen stays black even after doing PRAM and other tests.

Hi, Screen stays black...

Hi, Screen stays black even after doing PRAM and other tests. Seems like it fried something inside and I cannot get anything even though the Mac does switch on and off with the button on the back - screen still stays black!

Technician's Assistant: Have you tried a PRAM reset on your Mac (rebooting and holding down Command, Option, P, and R)? Or rebooting in Recovery Mode (holding down Command and R)?

Yes many times, but nothing

Technician's Assistant: Anything else you want the Mac Expert to know before I connect you?

If it is fried how do I remove the hard drive to save it?

Hi Richard, I did PRAM many times very carefully as suggested and also the SMC reset but all to no avail. Perhaps you can securely connect with a blank screen but I sure can't... Thanks for coming back to me.

Ok, not with a black screen I cannot yet, but disconnect the power cable then hold the power button for 60 seconds then release.

Then connect the power cable, power it on and tell me how it then functions please

Pulled out the plug , pressed the power button but it does not come on again

Shine a flashlight at the screen at a 45 degree angle.

Do you faintly see the screen?

OK it is on again, did what you said about flash light but still no screen

Thanks

It is the internal display adapter that has faulted, this now confirms it

I am really sorry about this and you are going to have to return the Mac to have this replaced. It will be covered by the warranty if this has not expired, and the replacement will be done at no cost to you.

I am really sorry about this, and if you have problems, or would like any additional information or assistance, please do not hesitate to let me know.

Thank you

What Customers are Saying:

Hi John, Thank you for your expertise and, more important, for your kindness because they make me, almost, look forward to my next computer problem. After the next problem comes, I'll be delighted to correspond again with you. I'm told that I excel at programing. But system administration has never been one of my talents. So it's great to have an expert to rely on when the computer decides to stump me. God bless, Bill
