iphone 3gs dead fl8_rf sparkled/burned & iphone how to solve its hardware issue

On March 27, 2015, Posted by , In iPhone, With Comments Off on iphone 3gs dead fl8_rf sparkled/burned & iphone how to solve its hardware issue

I have an dead 3gs here. history heavy drop. i attempted to find the battery voltage at other components. When i touched fl8_rf (close to smp3i pm ic )there was a light, it burned.


Any ideas how to proceed to find the problem ? It is a resistor right ? Should I jumper it ?

Do I understand right that this burn means that there is a problem somewhere else causing that. a short maybe ? Or maybe I did cause a short by measuring wrong ?

I am a little stupid about reading schematics and about proper measurement. But I am very motivated to learn 🙂

thanks,

kiez
