Hi whats the fix for this, ive bought this phone recently so i dont know the full history of it but the phone hasnt had water damage, and ive replaced the screen twice and problem still happening. Is it a faulty chip in the logic board that controls the digitizer that i could replace?

Hi,
1) Check whether surrounding components missing or corroded around BCM5976
2) Heat location of BCM5976 carefully : 400C* is enough and don't heat over 20Sec
3) if above two not works Change the BCM5976 with upper and below caps

Thanks for your quick reply i think your right with the chip being damaged, the shield over the chip has being removed and i can see that there is a discolour around the chip, have you a link to a video that i could watch? is it hard to replace and what tools needed. Id like to try and fix this myself, be a nice achievement.

currently i don't have apple 5 logic board to show how to replace it. you should have experience to replace BGA chips as it is not easy. don't give up and dry to fix it
* if you replace it you are one of best BGA re-worker
* if you failed you will learn a good lesson about BGA reworks and it may valuable than you phone
* if you fail today keep the logic board safely and someday you will be able to fix it, if i say simply practice make perfect
by the way why don't you make my answer as accepted? :-)
