Ipad 3 no power on logic board, L8112 2r2 hissing sound.

Hi

Im new to Ifix it so thanks for having me.

I was charging my ipad 3 last night. When I woke up this morning it was completly dead.

Being average to good at electronic repair I opened up to see what was going on.

Tested battery it was fine. I have noticed a hissing sound coming from the l8112 2r2 coil. Its also going to ground.

Any help greatly appreciated.

Thanks
