1 No video after resetting SMC and PRAM
Hey all...
I have a late 2011 MacBook Pro that has had the graphics card replaced through Apple's replacement program. Just the other day however when I opened the computer there was no video. I can hear the fans spinning, but I can't hear any other activity (of course I have an SSD so there's not much other activity to hear).
I have done all the recommended things on the Internet such as resetting the PRAM and SMC. I took out the memory modules and powered it on and am hearing the error beeps.
The computer makes the chimes when I power it on and the keyboard lights up but there is nothing after that. I am happy to replace some of the hardware myself if I know what the issue is but I'm having a hard time nailing it down from help forums and past issues that others have had.
Thanks for your help.

Could you try hooking it up to an external TV to see if you get any image on there? If it works, the problem could be the screen itself.

sorry the PRAM didn't work for you. Try an external monitor as suggested above or try target disk mode to test the screen and startup for us.

Yes, I tried the external monitor as well and nothing. Any thoughts?

How are the logic boards from ifixit or other vendors? Will they have the same issue? Thank you for the help.

Try on re-installing the RAM one at a time then power up, might be 1 RAM faulty.
