MacBook won't Power on After Screen Replacement

I replaced the screen in my A1278 MacBook Pro and now it will turn on - show the apple logo - and then shut down

Also the screen has an odd blue-ish tint to it and when it first turns on the back lights on the bottom are really pronounced

Thanks for the help

Answer this question I have this problem too

Is this a good question?

UPDATE: I got it to turn on - now the screen just occasionally flickers - could this just be a bad LCD?

Its possible its a bad LCD, but also it is possible the connectors arent sitting right. I would clean it with contact cleaner or Alcohol and reseat the cables.
