iPhone 4 with water damage, dried out, now working, but no ringer, iPod sound, etc.

My iPhone 4 was dropped in water and I let it dry for 2 days. After 2 days the iphone luckily booted up and all things were working except the sound is gone - no ringer sound, no ipod sound, no volume bar in ipod. the external volume buttons work, but the ringer level is blank. Anyone experience the same thing and/or have a solution to fix this?

The only way to tell for sure is to open the phone and check the connection, but it sounds to me like the speaker is just shot. There is a lot of shiny copper on the Logic Board, and well we all know what happens with a penny in water.

The connection in the pic that is circled is your speaker connection. I do believe that is a pic of a 4S but it will look the same and be located next to the battery connector.

If this is is burned out it will look black, or even have a green looking mold and its shot. If its clean the the speaker burnt out. Hope this helps!

Thanks GuardDogTech!....So, apparently the ringer is working (I hadn't received a call before to know for sure), just when I click the volume buttons the ringer level doesn't appear. I can make phone calls using it the normal way and putting it on speaker phone and hear no problem. The things that aren't working are the ipod sound [volume level doesn't appear nor does bar that shows the progression of the song], sound in movies, sound in games and the 'clicking' noise of the keyboard when the sound is on. Are these controlled by different speakers...I thought I read there was only one.

Ok, Does the vibrate button work? How about the headphone jack? Go into settings/sounds and make sure all of your settings are correct.

Ok, if the vibrate button doesn't work, try the headphone jack. If you get sound through the headphones, back up and restore the phone. If the headphone jack doesn't work then you'll have to replace the headphone jack/volume button/vibrator switch ribbon cable. Let me know how it goes!

Vibrate button works. Headphone jack works with calls and listening to voicemail, but doesn't work for ipod sound, video sounds, game sounds, etc (there's just no sound for it to transfer to the headphones).

All settings look like they're correct (volume limit is off in 'music', sounds are all on under 'sounds' and when I hit the volume buttons the slider level bar for 'ringer and alerts' under 'sounds' goes up and down).

I'll try the backup and restore and see how that goes!

(Thanks again for all your help!)

No luck with the restore. It made a keyboard clicking sound for a fleeting second yesterday, but nothing since...

It's working sporadically now...almost like something is a bit loose.

This is caused by rust shorting pins in the dock connector, or where the dock connector connects to the MLB. Shorting certain pins makes the phone think it's connected to a sound dock, hence why you get no sound or volume control (they're redirected to the audio out pins which are connected to nothing :P).

You can fix it (sometimes) by (gently) cleaning the dock pins with a toothpick, toothbrush/paintbrush and compressed air. If that doesn't work, it's either a new dock connector, or a replacement phone depending on how handy you are (or aren't) with a screwdriver.

BMA, Before completely replacing the dock connector could I unplug the original ribbon cable from the logic board and plug in a new one just to see if it is the problem?

I'm not sure what his tells me, but I unplugged the flex ribbon cable from the board, turned on a music app, plugged the cable back in and got music from speakers for 2 or 3 seconds before it quit and went back into to dock mode

That's more than likely going to be the dock. Any you can by all means plug one in (if you can get hold of one) without screwing it to the phone.

Thanks BMA, I did all that plugging and unplugging whilst the phone was on so hopefully plugging in a replacement will not screw up the phone. I think I will order replacement from OWC as I didn't see any on eBay I was comfortable with ordering from.

I bought a dock connector off ebay for $5.85 total. Unplugged the installed dock connector from the logic board, plugged the new dock connector in and determined it was the problem and then went through the fairly tedious process of installing the new dock connector following the ifixit instructions. I was successful woohoo!!
Also i found you can do all the plugging unplugging, of the dock connector flex cable, from the iphone you want while the iphone is on without damaging the phone

Yay! Glad you got it fixed!

Most of the internal components are actually hot swappable (camera, vibrate motor, dock) - not too sure why though.

My wife's 4S is in a similar bind. Got wet. We dried it and all works but the built in microphone. If you use the mic on the headphones it works. Any suggestions?

Is the speaker (music from the bottom - not the earpiece) working? and do you get the volume slider? Finally, if you record a voice memo - does the microphone work in there?

It's a tough one to call - it could be the speaker assembly or it could be the dock connector. It could of course be the logic board, but I'd say that was unlikely.

I would be tempted to replace both the speaker and dock - both parts together will be less than $10 - so you won't lose too much if it does turn out to be the board (this will also prevent any corrosion in the dock connector worsening and causing issues later down the road ).

No, just the mic. Speakers are fine. Both the phone speaker and the larger speaker are fine. Charging works too. No problems with any of the other operations on it.

In that case you *should* be OK just replacing the speaker assembly, but I'd be tempted to replace both just in case (should be around ~$10 for both and it's easy to do if you're handy with a small screwdriver and have some patience).

The speaker is much easier to fit though if you just wanted to do that though .

An update. It worked for a few days but today it has gone funky. It powered off with 85% battery and when I restarted it, it went into an "infinite-loop" (apparently) of reboots without ever coming up to a home screen.
