Hello everyone,
To summarize, I have the same problem as [link|https://www.ifixit.com/User/4024488/Mohanlal+D|@mohanlald|new_window=true]. Everything else functional, but the display is black. Replaced with new screen, but it did not fix anything. I then suspected a problem with the LCD display/flex cable and then disassembled the whole camera. I noticed a very tiny copper piece missing from the LCD display cable. I could not get my camera to focus on something so small, so I created a few graphics to explain the potential problem. Just wondering if that missing piece of copper is enough to cause a black display.
