Hi MR, Went to my parents for dinner the other night and my mom gave me her iPhone 4 that took a trip through her washing machine. I decided to check and see if it was a total goner before selling it. What I've found so far is that everything is working properly, the logic board is fine, speakers, mic, camera, battery is all in working order. However, the screen seems to be the only issue. It will not turn on. Though it does flicker when the phone turns on and the digitizer is working properly as i can slide my finger across and hear it unlock and I even managed to dial my number. I opened it back up and checked the ribbon for the screen and it's hard to tell but there may be some slight discoloration on a couple of the contacts, probably corrosion. Does anyone have any suggestions for anything else to check or perhaps clean off the corrosion so I don't have to shell out the $150 for a front display assembly?
