iPhone 4 - Blank screen, backlight only, water damage
After my iphone took a quick trip down the toilet i rescued it, dried it off and left it in rice overnight. 24 hours later I tried to boot it up, no luck, I conneted it to itunes and the computer did pick it up, and the phone made the usual noises, and even connected to my bluetooth headset, but the screen woud just not come back to life, it does however have a background glow when any buttons are pressed, so backlight must be fine.
I assumed the LCD must have been damaged but before I ran out to get a new one I dismanteled the phone (using an online guide), and transplanted the screen from a perfectly operational iphone 4, but still the same result, backlight only.
I put the good iphone back together, left the water damaged one in pieces and put it back in rice.
Does anyone have any other suggestions? surely the logic board isnt dead, there is no visible damage, corrosion etc.
Es esta una buena pregunta?
