iphone 5 no power on but L2 heats up – bundle of problems ! old iphone set looking help anybody

On January 25, 2015, Posted by , In iPhone, With Comments Off on iphone 5 no power on but L2 heats up – bundle of problems ! old iphone set looking help anybody

Hi guys, I could use a little to be helped Along with this one. Iphone 5 Along with very very little water damage, mostly in not significant areas. Cleaned it up anyway.


It doesnt turn on but when connected to power I noticed the L2 coil getting really hot. The meter shows a short between pin 2 of the coil and ground. I was hoping it could be the zenner diode D7 but no luck…title=frown

It looks like the U7 might be the culprit as the short leads straight to CHG_LX (pins H1 and H2 on U7). Is my assumption correct?

Has anybody else dealt Along with this issue before?

As a last resort I will disconnect L2 to prevent the VCC Main to get to CHG_LX just to see if the phone comes back to life, as this short is apparently killing the main voltage.

Any to be helped is really appreciated!

Thank you

PS: already tried: different battery, charge port assy, screen etc

No Comment so far:

    I have disconnected L2 and no luck. To my surprise, the short is still there but in front of L2.

    This means something on PP VCC MAIN is shorting out, but this doesnt explain why L2 heats up when in circuit ????!!!title=confused

    Anybody??? kindly to be helped!!! This doesnt make any sense…
