Lumia 735 Charging Way
 
Hi Guys,
have a Lumia 735 which wont charge with USB.
Changed USB Connector already without Success.
The Phone charging with Wireless Charger, but not with USB.
Is there an IC which I can bridge?

hi ,

first check vchg in voltage at J3300 , it's about dc 5v there . if voltage is ok then remove V3300 (marked in attach picture) & short it's two points A1+A2 (described in attach picture)

connect charger & check if still same problem then remove both Z3300 & Z3302 (marked in picture) . if problem still remain then you need to replace charging regulator V3301 (marked in attach picture) .
