Re: toshiba satellite c855d-s5320 need help
Thanks for the response friends. based on schematic of smdflea i checked U6100 TPS51123 is defective, so i replaced with equivalent RT8223M, now there is 3.3v and 5v but there is short on 19v now,and i found that 330uf 6.3v capacitor positive side is shorted to ground, ill tried replacing with tantalum 330uf 6.3v but still the same issue possitive side is shorted to ground but when i removed the capacitor the possitive side is not shorted to ground and plugged charger lights goes present.can anyone help me on this please

If C6100 was a ceramic cap replace it with a ceramic cap. I don`t see why the short would go away after removing the replacement cap,then the short is back with the cap in place, unless the replacement cap is also shorted ,or your measurements are wrong. The + side should be 3.3V .Last edited by SMDFlea; 10-02-2018, 05:29 AM.
