g5pw, I would start with checking the dock connector as well as the battery. Check the voltage on the battery connectors and see what you get with your dock connector plugged in. My concern would be that someone else already did a solder job on it. The first thing I would definitely do, is to clean the logic board with isopropyl alcohol. Use [guide|5825|this guide] to clean your phone. It was written for a 3G but most certainly applies to yours as well. Make sure that all connectors and cables are free of any corrosion/debris. If you do not get the appropriate voltage from the charger, check the fuses to make sure they are working okay. Oh, and do not forget to '''replace the battery''', especially since it may have had water damage. The iDevices batteries do not like any kind of liquid exposure. Check the attached image for some of the voltages for you to check. Hope this helps, good luck.
