iPhone 5 no service or no signal.
I had a iPhone 5 with liquid damage. I cleaned all the corrosion and the phone worked all fine.
Now after 5 months the phone doesnt find any service or signal. tried resetting the network settings, new software, used different sim cards
tried another antenna cable ( dock connector )even used another back case. imei, baseband all ok. date, time ok.
My question is which components do i have to troubleshoot so i can find a solution. Which components or ic's is related to no network, or no service. I got a scrap iphone 5 motherboard were i can take out components. Got the necessary skills to solder. got also the schematics.
Hope you guys can help me out
Is this a good question?
