need to know the value of some components
Hello everyone i need to know the value of R9C30 plz and R9D3 help
those should be ground from both sides? that's not right and i cant find the trace fo those

@freebaze so about this small capacitors C9D18 it should be graunded on both sides. I know it's strange, but im still learing how this all electronics things works. I guess it is just small capacity and small rezistance capactior so it 'beebs' on both sides. However one side should has higher(about 1-2ohms) resitance.
Second thing. There is this little resistor with very small resitance and it's something like test point so u can test your mosfets by putting your probes like in this proffesional image :P.
You should see on your multimeter (IN DIODE TEST MODE) something around 0.6-0.7. It means your big mosfet is ok.
And remind me, how is your xbox now? I mean is it still turning on for 5 sec?
这个答案有帮助吗？

@werfex thanks dude appreciate it
So can i buy a 0.4 ohm resistor can't find it online 🙄
@freebaze That's the tricky point. Im pretty sure that it's actually 0 ohm resistor.
Here's why companies are using them :
"Using zero ohm resistors reduce the cost of jumper wires insertion. For mass production, it's important to keep the cost down. Using an additional machine for jumper wires results in a separate setup and process cost. Therefore, a zero-ohm resistor is the perfect alternative that saves cost and time in assembly." - some random site after searching 'why are there 0 ohm resistors'.
You can maybe use just wire instead.
Good Luck and ask if need help
Ok man thanks for the good info
So i did everything for this xbox and still didn't turn on still beeps on and off so fast no short on 12 volt rail mosfets checked and changed one, changed power ic so now what it's the rams? Is there a way to know if the rams are okay or not and the weird thing (i guess) the apu is not getting hot at all when i try to turn the console on any advices?
