Water Damage no backlight and power button not working
Recently took a swim with my iphone 3gs and afterwards I couldn't turn it off so I took it apart and unconnected everything. Did the rice trick and placed it in a dessicator. After two days plugged the phone back and pc and mac can detect the phone. The only problem is that there is no backlight and also the power button won't turn on. When plugged in I can hear it press button, did a system restore and can only place emergency call. Need to jailbreak and bring it through DFU mode. Any suggestions what I can do to work on this problem?
edit: Thanks for all your help, I cleaned it in Isopropyl and was able to get the power button working again. The screen is still dark and I've noticed that the home button is not working''. I plan to open up the casing surrounding the logic board to see the damage. Anything other suggestions for me to do to check up on the backlight and power button?
