Chosen Solution
Bought the phone that apparently had a problem with the volume buttons. Opened it and the water indicator from the logic board was red, although the one near the sim tray was white, so I assume partial water damage. I took it apart and washed the entire logic board with 99% isopropyl and installed a new upper component flex cable to replace the buttons. the problem is that after all, only the volume down button does not work, just like with the old flex cable, I don’t understand why. The volume down button works randomly for some time and then I have to keep clicking it for a few seconds until it works and then stops working after a few minutes. Have also tried switching the button covers and don’t know what else to do to fix this. Would appreciate any help. Update (12/15/2017) Here’s a picture of the connector itself, looks pretty good to me, no signs of corrosion that I can see.
Here is a picture of the FPC connector to the volume down (FL4712, DZ4712, to C4712) and Schematic
Try cleaning the connector better and seeing if any components are missing. I think there is an inductor between the connector and the CPU so if cleaning more won’t fix it ask me and i can show you where the component is.
Hi if someone can help Plus and minus volume buttons not working. Silence switched and power button is working. Changed the ribbon cable but same symptoms. iPhone 6s 32gb? Thanks
I have cleaned everything I could and replaced the cable with a new one and the problem returned after some time. Don’t know what else to do. The weird thing is that is just the volume down button that is not working.
