There’s a short on that rail and it’s preventing the Xbox from starting I’m guessing I’ve removed components and put them off to the side didn’t fix short though if anyone has any ideas where that links back to it would be much appreciated
@caleb7777 how did you check this? It ’s an LDO Voltage Regulator. What is the reference designator? Looks like U3C3. The importance of images is not just components but also reference designators etc. since those can give us a lead as well. U3C3 is a voltage regulator in the standby switch circuitry. I suggest that you check the voltages according to this
which is from here There are ground pins on your regulator so we need to know how you measured etc. Here is the datasheet CAT6243 for the regulator and sounds like you measured the Adjust pin.
