Hello mate.

Those symptoms often means U10_RF, Avago Power Amplifier, has lost contact with some of its pins. Please check if this is loose.

hi,

Strange thing with iphone 4s wifi problem.
Fixed several 4s phones already by exchanging wifi chip.
Now I have on that is making some trouble. put new chip on it already 3 times.

on startup greyed out wifi slider problem remains, no wifi hardware adress.
When i start uo and firmly hold my finger on the wifi chip, it comes up and works. I know first thing you would say is bad soldered chip. But on last solder i made sure all the black glue was gone. And when flowing started i could see the chip slide on its place. 99% sure that the wifi chip is soldered well on it.

maybe a pad lost connection to its underlying layer?

Also i lost R49_RF and C13_RF. I directly jumpered the output to the coil L1_RF.
Like I said when i apply pressure to the wifi chip, everything is working. Seems tat it is not missing the RC combination. (Iwill solder them back with components from another phone)

Can someone tell me what the fuction of C13_RF is? And strange that R49_RF is 0 ohms value.

Could it be related to my problem?

kind regards
