What to do when screen seperates

Not sure if you can see in the picture but looks like after water damage my screen lifted and I only have the two ribbon cables vs three, is this repairable? When I connect the phone to a PC with iTunes, it sees the phone but will not factory reset. I opened it to dry it out hoping that is all that was needed, it may be fried. Thanks for any advice to try. Roger Conant conant.roger@gmail.com
