The screen on my friends iphone 4 suddenly died. I replace the screen and the phone wont turn on… I think the problem is somewhere on the board… Where should i look and what shoukd i look for?? Tnx alot guys..
First of all, try holding power and home for 10 seconds. Then, check the connector sockets for (water) damage. If everything looks fine, try another battery. If that doesn’t work try a new screen
I tried anew screen and a new battery and tried the thing whit the buttons… The ituns recognize it but thsre is no pic!! There is a pic of the mothere board.. Everything seems right no?!
For those of u that wanna how i fix it.. I just cleaned the connections whit isopropyl alc and installed a new screen… Tnx for tries …
