I replaced my iPhone 6s battery however when connecting the screen back to the phone I accidentally pressed the power button on and a the connector started smoking. Now the screen will not even show dead battery sign, what will have happened and will it be repairable?. I can answer the phone by swiping in the area, but can not see a thing. Cant back it up or anything as i need to trust the computer, which I can not do. any help will be appreciated.

It sounds like you may have shorted the back light circuit and caused the Fuse/Filter to blow (FL4211 in the schematic). You can measure its continuity to confirm that it has failed. And replacing it should solve your issue. I will however warn that replacing such a small part is not easy and requires a lot of skill and practice.
