Hi Rany. Your description sounds like the issue i have. iPhone 5c dropped all works but the screen/touchscreen. Tried a new screen but no luck. How can I check if its the backlight issue? (but lack of response from touchscreen makes me believe there is more to it) Kind Regards
Hi Daniel, So your phone doesn’t show an image/or backlight AND touch is not working? Are you sure it is a drop, not liquid damage? Back light, image, and touch are 3 different functions with somewhat different “circuits” on the board. They may both be damaged, but more often it is just one of the 2. I’d start with the following:
- There are 3 screen connectors on the board. Clean them with a cotton swab dipped in 90%+ isopropyl alcohol. Then try reseating your screen and re-booting your iPhone (press & hold home + power buttons for ~12 seconds straight then restart your phone).
- If no change, remove the black film (very carefully) around those connectors on the board and look under a magnifying glass for missing/broken/part removed components.
- If you see nothing wrong, try a KNOWN GOOD display, something that you know for sure works on a different device. OR transfer your logic board to a known good phone. Let us know what you find out at this point.
