Chosen Solution
Hey everyone, here’s whats happened. I replaced my iPhone 6 screen for the second time and everything went well, the phone worked perfect. After a week or so the display would sometimes glitch out and sometimes even go completely black. This happened very randomly and I discovered (by accident) that whenever it did go black the only way to make it come back was to drop the phone face first onto something relatively solid. Obviously this wasn’t any sort of long term fix so I went home and took it apart and reseated everything and tried to turn the phone on. This time the lcd would not turn on at all. I put on the old screen and it did work but then after going back and forth dissembling and re assembling the connections and making sure everything was correct neither screens would turn on. The phone is recognized by itunes and when plugged into the NEW replacement screen makes the charging blip every 5 seconds but shows nothing on screen. When the old screen is connected nothing shows up at all (so I don’t think its a back light issue) but the phone does NOT make the repeated charging blip. At first I assumed it was just a faulty LCD on the replacement screen but now I think I have damaged something deeper. Any expertise would be appreciated as I have scoured the web endlessly looking for an answer. I cant see any damage to pins but obviously im no expert so i have attached photos of anything I thought might be important. IMAGES: https://imgur.com/a/JAtsg
The pictures aren’t clear enough but nothing seems out of order (the connectors look good). Did you disconnect the battery through all of this connecting/de-connecting of the screens? It sounds to me like either the backlight or LCD circuit was damaged. It could be worse too because the charging beep shouldn’t repeat. If that’s the case, it sounds like it is boot looping too. So re-reading your question, it seems the replacement screen causes the repeating beep; that’s not a good sign. Try disconnecting the screen (remember the battery!) and connecting it to iTunes. If the phone is properly recognized and can sync, then your only problem may only be LCD/BL related. If it is not recognized, then more damage was done. You will probably have to find a reputable micro-soldering repair shop to solve this.
