Replaced screen, slow and fan on maximum

Hello. I replaced my screen but now the macbook pro is really slow with cernel task being up at 500-600% and the fans move at full. I have tried to change the screen back to the old to see if it were any of the cables but it does not seem to help. I have also done a hardware test on the mac which also didnt help. Any suggestions? thanks!

Answer this question I have this problem too

Is this a good question?
