iPhone 4 blank screen but backlight works water damage – bundle of problems ! old iphone set software or hardware issue
I dropped my iPhone 4 under my shower for a split second about 2 weeks ago.
For the first few hours I couldnt get any sound (cleaning out the headphone socket sorted this).
Then the next night after a whole day of using the phone, the screen suddenly went blank. But still backlit!
I managed to get all my data off the phone using iTunes luckily.
Also, using iTools, I can see the virtual desktop so I know the phone is working. I can also ring it etc.
I have completely dismantled the phone, used electrical contact cleaner, compressed air. Lightly tapped the logic board on table. Left the phone in a bag of rice for days. Held home and power buttons. Reinstalled IOS6. Reset to factory (using iTools).
Moved the logic board into a spare phone from work and the blank screen problem transfers itself.
I cant see any obvious damage to the logic board. The 2 spot water sensors are still white, but the headphone and charger ports are red.
The phone charges ok but battery gets very hot now (again, problem transfers itself when logic board moved to new phone).
Am I missing anything else? Im just going to purchase a smashed iPhone and use the logic board but I dont like giving up easily as you can see
And Im well aware now what I should have done when it first got wet but I cant do much about that now lol.
