I have mid 2010 iMAC 27 inch purchased 2011. It was working fine until a couple of months ago. Now, the issue is, the chime boot up sound loops and no screen display. I have removed the screen and tried to verify the Hard drive. [br]
I bought a SATA cable from best buy and tried connecting the hard drive to mac book laptop using SATA cable. [br]
The hard drive didnt show up in the Macbook Pro. I thought hard drive is the problem. so I bought another hard drive but even that didn't seem to be recognized with the SATA cable.[br]
[br]
Not sure how to connect the internal hard drives to the macbook pro. [br]
[br]
3 Questions.[br]
1) What component could have failed to load the iMAC Screen if it is not hard drive issue?[br]
2) Should I try replacing logic board or graphics card or cpu?[br]
3) What is the best way to trouble shoot connecting internal hard drive to macbook pro?
