Is my Audio IC broken?
I bought an used iPhone SE from eBay. The Seller only told me that the Screen was Cracked. Today it arrived and I also noticed some other defects on the Phone.
The bottom Microphone doesnt work, and the Headphone Jack doesnt work either.
It only sometimes sounds clear after I put the volume to max, and after a few Seconds it sounds very distorted again. Im pretty sure this isnt a loose connection, because if I turn down the Volume, and then Up, its distorted again.
I already tried to Reboot, Reset, Reinstall iOS, Replug the Ribbon Cable… Nothing works.
What do you think? Should I replace the Part with the Headphone Jack, Lightning Connector and Microphone? Or maybe there is a damage on the Logic Board?
I hope you can help me.
