screen became almost black
Suddenly, I noticed that the phone’s screen became very dark. I needed to put the phone near by a bulb light to be able to see what is on the screen as this made the phone increase the light of the screen. At the same time the phone was very hot although it was not charging (not connected to a charger). I tried to reset the phone however, I noticed that the phone is heating more so I opened the phones cover and disconnected the phone’s battery. I waited few minutes until the phone cooled down then I connected the battery. at this point something started to burn inside the phone. some smoke came from under the metal plate where the red arrow is pointing to in the uploaded photo.
I believe there is a burn mark on the back of the removed little cover. It can be seen on the second and third images.
Does anyone know what I need to do to repair the phone?
Thanks in advance
