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.
Hi there, I’ve been in your shoes many times. If you replaced the LCD/Digi with a new one and you still have no luck than its very possible your looking at a bad board. Ive seen iphones with NO signs of corrosion yet they have problems much like yours. Try cleaning off the connectors on the board with rubbing alcohol if you havent done so yet. If none of this works, than try to backup/restore your iphone (slim chance this will fix it, but i’ve seen it work before). Last if NONE of the above work and you run out of ideas than try soaking your board in rubbing alcohol for 4 to 6 hours, the dry it out in rice for 24 hours. I have recovered many Logic Boards with this method, but I use this as a last result before the customer buys a new phone. Good luck. -Nick C
I dropped my phone in a cup of tea a few days ago..it flashed on and off then the screen went black..i didn’t do anything to it to dry it out..next morning it was working fine and did so for about 3 days..then it just flashed and went black again…now for 2 days i’ve had no screen but i can hear texts and emails /calls…what if anything can i do??
so the phone is fully functional without the screen? is the vibrate ,answer a call,or turning off the iphone works>? if you all the above works then it must be your fauly lcd ,or check the connection on the board & the ribbon cables ,its either that or the backlight coil ,or else anycase you should open your phoen and follow the method above ,and you might also try a hairdryer with correct ammount of heat,check with magnifying glass or better microscope for any visual damage of the parts ,

hi my iphone 4 fell down the toilet but it had a single crack on the screen. i took it out and tried drying it out. long story short, it rings and vibrates, but the screen is black. I dont mind fixing a part on it (rather than buying a whole new phone) but i need to know what exactly i need to buy and if it would really work?
@pollytintop, i have the exact same problem, faint light can only see the screen faintly, it’s black mainly, how do I clean the LCD connector , I have a 3gs
My little girl got butter on my iPhone when I turn my iphone off the screen turns black for a minute but then it turns back on what should I do I feel like going to another company I’m with sprint there trying to charge me $49 for a new one
