Black screen with light at edges from missing cap
Hi, After replacing a cracked iPhone 5 screen, the new screen worked OK but I opened it again to remove the logic board as the rear camera was not working. After replacing the camera, the screen did not work, it is black when turned on but with the screen lifted away from the case I can see white light at the edges. Otherwise the phone works (vibrates etc).
I have searched this forum and many others and see that a common solution is to test/replace some filters, coil, ic etc. But I have a slightly different problem I think. Near the power connector J6, I accidently flicked off one of the caps. This is C9 from pin 7 which looks to be the main voltage to the components.
Just wondering if this could be the cause of the screen problem. Although I know that I need to get this fixed, given that this part of the circuit looks to supply power to many components, I wonder if for some reason the screen is impacted while the rest of the phone seems OK.
Thankyou for your help
Is this a good question?
