Internal ear speaker not working after screen replacement
I have replaced the screen on an iPhone 7plus now the internal speaker doesn't work. So I replaced the proximity cable and the speaker. Still no sound replaced the screen again. But nothing. Everything else works the proximity the selfie camera all work. Any suggestions? This it about the 30th 7 or 7 plus I have done. I have not had any other problems before this. It worked before I replaced screen. I even tried the old screen and Proximity ando speaker did not work.
I have replaced the screen again and the speaker . I have everything also tried to put all original screen and proximity cables and speaker back on does other work . I have repaired at least 30 iphone 7 and hundreds of the others. I have never had any problems like this . I'm a capable technician of trouble shooting problems. But this has me stumped. There is not any apparent damage to connector either. Is there not somebody out there that has had the same issue with the iPhone 7 plus?
