iPhone 4s Display Assy Replacement

Mon problème

My son in law's phone fell and the screen completely cracked.

So decided to help him and ordered the part from IFIXIT

Ma solution

Installed following guide as always, have done it many times, but always follow the guides ,like pilots follow their checklist before taking off no matter how many flight hours they have.

After powering up, success ,the display looks brilliant but when trying to scroll the phone will not respond.

Went over again the install and verified each connection meticulously.

NADA.. So decided to check the connectors more closely.

Used my BAUSCH & LOMB 7X Measuring Inspection Magnifier No. 81-34-35 and found that the Digitizer connector had what looked like a solder blob .Seems a fluke from the factory.

Called IFIXIT in and spoke to Chris. Explained situation and after that he will send a new Display and I will send back the one with the defect.

Excellent service from Chris .I sent him also a photo of the "offender"

As soon the new one arrives will inspect and install.

The saga continues LOL.

Thank you IFIXIT for your service and respect.

Mon conseil

Well, I can say that will inspect using my BAUSCH & LOMB 7X Measuring Inspection Magnifier No. 81-34-35 before installing any part just in case to trap any possible part flaw..

Would be a very good preventive action.
