iphone 4s U9_rf heat – iphone problem , and strang looking help anybody

On January 25, 2015, Posted by , In iPhone, With Comments Off on iphone 4s U9_rf heat – iphone problem , and strang looking help anybody

Hi there ive got one 4s which is getting heated while sim inserted……


And it has not network coverage….

i disassembled the phone and found out U9_rf getting heated. I removed U9_Rf….

But When i check L7_rf … it is still short Along with ground…..

I removed C18_rf, C22_rf, C24_rf, C26_rf, C32_rf….. Still L7_rf is short to ground …. so i finally removed U10_rf…. but i still get this VCC_GSM short to ground…..

This is the second time ive to this same problem…..

Anyone who solved similar problem ?
