820-02016 not working

[bartech]

there is short on ppvbat_aon_chgr_reg, i change u5200 but the same
i take out r5261/2 and short is alsow on chgr_cs_p/n

Remove F5200 and check which side the short remains.

at ppbus_aon

Then why replaced U5200???

What is the exact ohm resistance to ground?
Compare with the readings on all secondary coils.

 

[bartech]

1,2 ohm

?

come back again, it starting and work till you try to watch youtube... when you push play on youtube - pink screen and restart, now its not starting.when i connect power there is shot on F5200 and u5200 get hot but changing u5200 dont change anything

"when i connect power there is shot on F5200"
Are you checking in diode mode with power applied???

Allow 10-15s once power is removed (including battery), before checking in diode mode, or ohm scale.
