HTC U11 main mic and mic 4 dead, slow charging speed

[NemesisMF]

Hello,

my htc U11 fell down. The screen is still working but the main mic and mic 4 are not working anymore. Also the charging speed was low and the lower speaker didn´t work. I´ve bought and replaced the usb board. The charging speed is ok and the lower speaker is working but the main mic and mic 4 are not working. Do I have to change something else? I´ve tested the audio functions via *#*#3424#*#*

Thanks in advance
