Replaced Power Button Flex Cable - Proximity working Button still not?
My girlfriend's iPhone's power button has been broken for months now after she let her phone fall, so I decided to fix it. I bought a new power button proximity light sensor flex cable from China via eBay.
The previous button wouldn't even press/click and after disassembling the phone, I noticed that it indeed could not click, as the black tip of the switch did not exist as it probably broke off.
So after replacing the switch-sensor-ribbon piece, the button does click now. I was looking forward to it working again, but unfortunately after reassembly, it's still defect. I've tested the proximity sensor and it does works, so it can't be the ribbon connection that's bad...
Could it be a partially broken component I ordered or is it something on the logic board? There is definitely no visible tear on the flex cable...
I'm even trying to figure out how to test connectivity with my DMM (is that possible? has anyone got any experience?) it's a pretty small component.
Thank you! :)
Is this a good question?
