Hi,i've accidently dropped my iphone 4 in seawater.i immediately took it out and after an hour or so i diassembled it and let it dry . after a few a days i reassembled it and found that the rear camera was not working so i took it apart again and found some rust near the resistors which are at the part where the camera connects to the motherboard.i then cleaned the area with isopropyll alcohol and a brush . but to my dismay two small resistors came off near the camera circuit . now everything in the phone functions except the camera.Is there anyway that these resistors can be resoldered or the pcb repaired ?or should i get a new pcb ?

james, any chance you can post an image of the parts that came off? Take a good picture of the adjacent parts on the logic board as well. That way someone might identify the parts with the schematic. Any markings on the components and/or the logic board will help.

thank's for the reply mate .i've took this picture with an old phone but if its not clear i'll upload one as soon as i find a decent camera.and once again thank you for you time.

Sounds good. The better the picture of the area surrounding the lost components, the greater the chance to find it on the schematic.

iPhone 4 Teardown take a look at a zoomed in version of a working board..think you've knocked/scrubbed off 3 smd parts. As to whether you've anything to solder to, and the tools needed for the job is another story. If you aren't skilled or equipped then look online for someone who can do the job. One of the guys who answers questions on here called Hector Truong may be able to give you some good advice on how to proceed. Click on "answers" go to "users" and look for his name, clicking on that should give you an email contact.

Sounds like you scrubbed too hard. If the solder pads are still present on the PCB you might be able to locate the needed resistors and re-solder them on.

Using a digital Ohm meter can you measure the resistors? If not try to locate a junker iPhone to pull the resisters off of.

Otherwise you'll need a new PCB
