iPhone 5C Screen turns on but it is black. Damaged components.
I bought damaged iPhone 5C recently. The seller told me that it did not power up and screen was replaced before. I managed to fix power up problem, however, I encountered other problems related to display. At very beginning iPhone LCD only showed dark screen. Do not get wrong, it could see that display itself works and backlight coil is not damaged as display showed some kind of color. Later on I have noticed that there are two missing components below LCD connector and I assumed that is the problem as when I was checking the screen started to work and disappear again. I wonder if anyone could tell what those components are and where are they located as I have been trying go find schematics of iPhone 5C online and I couldn't. I am adding a picture of components location.
Also, I decided to give one more chance connecting display and found that it works right now (by some kind of miracle which currently is not understandable to me) but I have problem as digitizer does not respond to touch (could it be display problem itself?). Also, the other problem is some kind of squares I can see (picture below) which I assume could be because of missing components? Can anyone clarify this information? There is a picture of iPhone display.
Thank you for your help! It is appreciated.
As requested I am adding picture of missing components. Thank you.
