samsung galaxy S6 sm-g920f hardware solution and discussion - Page 4 - GSM-Forum

florow · 10-24-2016, 23:26

Hi,
I also have the problem, that my S6 (920f) deosn´t fast-charge...it charges VERY slow!
Also I cannot connect it with my computer...says "unknown device".
Apart from that, the phone works well!

I have changed the whole USB-Flex...testet another computer, another cable and chargin-plug.
I replaced the U8010-IC from the solution above...no luck! Same problem!
I really want to solve this problem. Does anyohne have any Idea what to try next?

kind regards,
flo

Mine was a board problem. Tried rehot on ic, no go. Probably cap or resistor on board in ic fast charge circuit. Tested with separate board and battery/flex were fine. There's a schematic floating around here with the full fast charge circuit diagram and testing.

first you check the lcd and other you check the lcd jack in main board if both were ok then change the display ic side of other near with bettery terminals

cy8ex · 01-06-2017, 15:04

i'm working in a samsung service center and specialized for G920,G925 and G928, if they charge only at 5V/420mA and sub pba(usb port with flex cable) is ok then in most cases the z-diodes or resistors(ZD8005 / ZD8006,R8021 / R8022) are the problem... if the charging screen pops up on display it has nothing to do with lcd

cy8ex · 01-06-2017, 15:18

on lcd problems you can rehot or change the PMIC U7001, Backlight driver DCDC U9002 and the mipi cm filters
