New display doesn't work properly

My phone’s display got kind of broken and I decided to fix it by myself, I bought a screen LCD display replacement from ebay.co.uk but now that I installed it the screen doesn’t works properly.

Here is my phone turned off:

Here is my phone’s screen, right after I turn it on which is static all over:

Later when it is booting, the screen gets divided to two part, top and down. Down part still static, top part gets divided to another two part which displays Samsung’s logo (with damaged color):

When phone completely boots up display is like this:

The digitizer and touch works fine and I have to touch the buttons on their original location even that picture is resized.

Here is a video for better understanding of the situation.

New display connector:

My cell phone connector:

I also installed back the original broken display and it works, so I don’t think that I damaged the phone connector or anything.

Any idea what is wrong and how can I fix it?
