Hello guys,
I quadruple check my dc mofset and they are not leaking.
But first one is giving me million and millions ohms in every ways (gate <> source <> drain <> gate) could it be this little b....?
But I get not voltage after first mofset 0V, I get 0.95V after 2nd mofset.
On my ic chip i get: (without battery)
ACN 0.91
ACP 0.91
CMNSRC 0.38
ACDRV 0.05
ACOK 0
ACDET 3.1
IOUT 0
SDA 0.1
ILIM 0
BATDRV 2.2

Hello friends,
I replace a shorted mofset (PU8104), now laptop is starting but no display, stopping at DRAMRST#.
Resistance to ground on PL8104 is around 1-2 ohm, quite low but voltage seems ok 0.995V
Any help would be appreciated it's a nice laptop !
Thanks. 😃 -
Hi, Recently my Samsung 4K QE55Q60AAUXXH just suddenly stopped working_ there is no any sign of life - no red light or anything..and think, after diagnostic, it is diode DM863c SF28e PK33 siyu or one of these four. Is there any alternative I can replace with since it is hard to find it in my country and to order outside is quite difficult. thank you... -
Hi,
A friend of mine gave me an iPod nano G3 to see if I can fix it for him.

This is usually an easy fix HOWEVER, on the PCB, I see no traces coming from the VIA and after searching the internet, I've found no schematics nor boardview for this device. With the pads gone from both sides I seem... -
