Opened my iphone 6s and now the screen is black?

I opened it up and moved the lcd wires around now its not working. The upper foam part for the wire is almost gone i was wondering if that could be the problem. Like there's metal showing I don't know if thats why but the screen is black and I can hear the vibrations and the text messages.

The problem is you opened the phone and shorted out the screen

Sounds like you have either disconnected or broken the lcd ribbon cable:

a) Pay somebody to fix it (replace the ribbon cable)

b) Pop that bad boy open and reattach the ribbon cable, or if it is split or broken, order a new cable (you will probably need to order a whole new lcd as the cable is likely attached to it) I haven't opened a 6s but have done a lot of others and they are usually attached.
