Connections between Surface pro 2 and LCD.

Hello everybody,

My LCD screen was broken and I decide to change this one.
After open my Surface, I disconnect the broken LCD meticulously. But any ribbons are perhaps broken because my new LCD doesn't restart!!
Now to change them, I would like to know, what is the signification of differents ribbons between Surface (motherboard) and LCD screen?

Thanks to you in advance.

See you soon.

Best regards.

Syl.
