after earpiece replacement front camera don't work

This is what appears when I try to use the front camera

Yesterday i replaced the earpiece, after assembling everything worked except the front camera.

I tried to replace it twice with spare parts which luckily I had at home but It presents the same problem.

It's possible that the camera is not broken?

I checked the pin 100 times, I carefully disassembled and reassembled many times.

What can I do?

thanks
