I got stuck after assembling the iPhone 4s

Hello everyone,

I just changed a an Iphone 4s display and the power and sensor cable.

After that the phone won't turn on, it just turns on when its pluged on the AC power adapter, even connecting it on the the pc it won't turn on. It shows the apple logo turns on and off.

Even though I get it turned on, on the power adapter, it keeps searching for network, neither sim-card recognition nor wifi. After it for a couple of minutes, the display makes like corrupted display pattern with horizontal lines and suddenly turns off :(

Note: I could not find where to put these two parts?
