Answer to: water( tang) damage itunes recognizes the phoneThis link (phone corrosion) is to an Instagram account I upload photos of corrosion I find in wet phones. These are examples of the problem your phone has. No amount of blow drying would have prevented this. While glucose isn't an electrolyte, the water the tang was made with undoubtedly had electrolytes in it. Electrolytes + dissimilar metals = corrosion. Add electricity and you speed up the process. There are over a dozen different metals in your phone. After working on hundreds of wet phones, I can virtually guarantee that your logic board is full of corrosion and short circuits. This is supported by your description of events combined with the physics of corrosion in wet electronics, and the fact that your phone produces significant heat where you shouldn't be feeling heat -- this is 100% a short circuit and if you let it continue by charging the phone or attempting to use it, you'll make it worse by burning out components. I'm in the United States. Myself and a handful of other people here specialize in ...
Answer to: water damage what should I doIt doesn't sound like you've addressed the water damage, just that it got wet and you plugged it into iTunes after replacing the port, or at least just plugging the new port onto the board, with no change in status. Thus, this should tell you that the port/dock isn't the problem and if you've not addressed the water damage, then what you *should* do is remove the logic board from the frame, then de-solder the board shields - all of them, then run the bare board through an ultrasonic cleaner to attempt to remove the corrosion left behind the water -- this is your root problem. Secondary to corrosion comes short circuits and burned out components, so once you've removed the corrosion, you'll need to test for shorts/bad components and replace SMDs PRN. If you lack the tools/knowledge to do this, then take it to a repair shop that offers water damage repair -- though most shops who take on water damage stop after ultrasonic cleaning. Generally, board-level repair for water damaged phones to return a working phone...
Answer to: Where to purchase SMD componentsGreat question and an important one for anyone wanting to take repairs to the next level. Here's the deal, many of the parts you're inquiring about are actually available from major parts suppliers like DigiKey, Mouser, Allied, and similar companies that can supply you with thousands of backlight filters, should you want that many. The key to ordering from them is understanding what the device schematic is telling you about the package size, rating, tolerance, etc. Armed with this info, you can use the search bar on those sites and find a lot of what you need (when it comes to resistors, capacitors, filters, transistors, etc). For connectors and microchips, it's a little more challenging. Surprisingly, eBay actually has most of the connectors you'd ever need, and the quality isn't horrible. You'll find that some plastics/nylon melt a little easier than others, so you may need to adjust your hot air if that's your tool of choice. Microchips can be found on eBay too. The problem with eBay is that you never know...
Answer to: iPhone 4 proximity sensor not working after replacing BLACK GSMFind yourself a sheet of prox/ALS gaskets and double them up, like you see in the pic. Problem solved.
