Put working sim, connect to PC iTunes and start over. Check date/time. Internet required.

I have an iPhone 5 and sometimes there is static in earpiece, loudspeaker and in headphones. Its during calls and also when recording video and audio.

@ryanna
Is it not a coil would it not be the same as the other one ?
5.6NH-3%-0.35A

If you have no power this is not the problem as it looks like part of GPS circuit

lshoa · 06-23-2015, 22:54

antenna filter duplexer
The full part is U17_RF

Your right i saw it too its for gps,it may be the same but iam not sure because its not on the schematics.

I also think this is not the cause of no power i will try to diagnose more then later i will still need this part i think this was damaged by previous shop when removing the battery.

Anyideas where to start for this no power problem?

start at the battery connector and work along the main VCC line for missing / hot / burnt / corroded parts.

Do you know the power on sequence of this unit?

I will check them, no short in battery, tried new battery but still not powering connected to charger without battery no voltage on pin1 and 4, with new battery phone must turn on right?
