water damage, now working, but dim display, need help with cleaning

I plan to try to clean my water damaged iPhone to see if that will help with the dim display, since everything else seems to be working. I realize this may not work, but figure it is worth a try. I have the tools ready and am already inside. I am not quite sure how the ribbons are supposed to unclip though. It seems there is a sticker on top of each, but can't really tell how to best approach unclipping them. Do they open, slide off, what? This may seem like a dumb question, but I don't want to do further damage by trying to force it the wrong way. Thanks in advance for any assistance!

Answer this question I have this problem too

Is this a good question?

This was my first experience at working on the inside of an iPhone and it was a bit daunting at times. However, I did manage to get it all apart, clean the inside (which surprisingly enough didn't look too bad) and get it back together. However, while it still works, it still has the back-light issue :( Does this mean I need a new logic board? Any other suggestions?

As far as I know if the backlight is not working, either the screen or the logic board is hosed.

This guide should show you how to disconnect all the cables that you need to. I agree with Nat though on the diagnosis.

My standard cleaning advice:

Once you're at a step where you can see the logic board, you should use some strong isopropyl alcohol (90%+) and a soft brush to remove any white-ish residue you see. Let the device dry <thoroughly> to make sure all liquid is gone (this will likely take a day or two in a warm, dry place if the device is opened up. Putting the iPhone in a bag of rice can also be useful at this point.) When it is dry, put it back together, and you will have your best chance of it working.

I dropped my 3G iPhone into water too and experienced similar problems, dim display at first and then after a few minutes of water damage nothing. I had given it up for dead at first until I discovered this site...

I followed the instructions to remove the display up-to step 6 and found drops of water 'here and there' within. Unfortunately when I pulled the iPhone apart at step 3/4 connector 1 pulled out by itself (Ooops!) so be careful.

To remove the connectors I used a small size 0 jewellers screwdriver and a very light/careful touch when prizing them up VERY gently from a corner, they will pop out but you will have to be very careful not to damage the cables (I did not have a plastic 'spludger').The connector marked 3 with the tab can be flipped up using the screwdriver too.

This is as far as I went on mine as far as disassembly was concerned.

I mopped up all the drops of water could see and gave all the exposed electronics a good dry with a soft tissue. I then put it all back together left it in a dry warm airing cupboard for a few days and then fully charged it up. I guess I was lucky...it has all come back to life !
