I tried crab4life's recovery process and it worked beyond my expectations. I had been using my Hero 2 with the LCD back and the dive housing for 25-30 dives without a problem. Last May, shortly after entering the water on a boat dive, and dispite my normal precautions, I noticed the latch wasn't fully shut and salt water was in the housing. I handed the camera to someone on the boat who took out the battery and SD card, while I continued the dive. Later that morning, I rinsed everything in fresh water and put the camera and back in rice and left it on the balcony in Jamaica so it got plenty hot! All I could get it to do after several days of this is the power light would glow for a few seconds then nothing. I brought it home and left it in the rice until now! I took it apart as far as I could and did the rubbing alcohol - vinegar thing and after 4 months got the camera to work but with some spots on the image. I used Damp-rid instead of rice, this time. Of course, I broke the microphone wire connections to the MB in the process. I then tried the LDC back and it came on but no image, just a cloudy looking mess on the screen. So I took that apart and repeated the process with it and it, too, came back! The image isn't perfect but good enough. I then took it to a iPhone repair place to resolder the mic wires and clean the sensor (I removed the lens but could get it clean enough). The sensor cleaning and resolder job cost me $10 and now everything works fine and ready for dives next week! Thanks, crab4life!
