Macbook Air black screen

Hiya,

I have a Macbook Air Model A1370 EMC2471 and when I try and turn it on nothing happens the screen stays black and no startup sound.

I have taken it apart and it seems to be a fault with the SSD, I take it out and put it back and it works ok for a while then I turn it off and leave it for 30 mins or so and its back to not turning on again.

Any ideas?

thanks.
