No loudspeaker despite replacement

Hi there,

I had a minor liquids spill on my SE (1 Gen). Shortly afterwards the loudspeaker stopped working. I’ve since replaced the loudspeaker itself as well as the charging port, headphone jack, etc. assembly. It’s still not working. Any ideas on how to fix this?

Thanks a lot.

Flo

It’s hard to tell without having a good look under the microscope to see what is going on. Maybe some of the liquid got onto the logic board and fried some components. Or if nothing is fried from the liquid spill, it could also be that you have corrosion on the board and that some of the components don’t make a connection anymore because the pads are gone. I would suggest to take it to a specialty shop that does this kind of repairs to have them have a look at it.

But maybe the repair will be more expensive as a new logic board/phone, so in the end you should take that also into account.

Thanks for your answer, Bram. Weird thing is, that everything else works just fine. I’m afraid getting professional help will be too expensive… Thanks anyways. If anyone else has any thoughts I’m happy to hear them.

Since you already opened the phone, you could take out the logic board and have a look at it with a magnifying glass to check for corrosion. You won't be able to look under the shields, but you can look at the more exposed components. If you see green-blueish stuff around components you have corrosion. The audio IC is probably under the shield as you can see here iPhone SE の分解 but try to look at other places first for corrosion.

But maybe as a first step, check if all the connectors are 100% in their socket.

I'll check that out. Thanks, Bram.
