Hi, I got this device with liquid damage.
Mainboard is cleaned and was not many liquid to see.
The display is not working. with another display the machine is working good.
The big connector looks pretty good.
I found that there is a burned backlight connector. So i soldered a nice...
I have this device here, no green/orange light, dont turn on.
found short R7121 Pin 1 to ground and high resistant R7121 and R7122
after replacing u7100 there was no short anymore.
So i replaced the R7121 and R7122 after that all was ok but i found there goes 6A in to the machine.
yes, that was for me the intresting part as well.
now i checked again and yes there is no 5V_S0, but I replaced already U7600 inbetween
so I measured bad S4 or bad S5 and have now a bad U7600. I am gonna replace it again and will post the measurements after that.
