Broken my camera cable... and my Mac is dead.

Hello,

I was replacing the drive with an ssd on my MacBook Pro 15 Unibody Early 2011,

and I broke the camera cable.

See photo in detail, the second photo, step 5.

I pulled too hard ... sigh ...

I don't understand the why, my mac will not turn on more...... it's only a camera cable no?!

I press the power button but no response from the mac ....

I am very sad,

beacause this operation I had already done with success

with my old black macbook 13 ....

I went to the Apple store in my city and do not want to fix it ...

Accept any answer and I thank ...

sincerely,

Andrea
