The Transistor and it's BE Resistor look like they were never installed to begin with, which makes sense as the one missing Resistor on both boards that I have here is installed there on that board, which would make it act like that Transistor was just on all the time, so no need for it. Both JDM-030 boards that I have on hand here look like this, but that doesn't mean there is another variation of the -030 that is supposed to be setup like that one you have there.
Hi,I already replaced the battery, as that was my first guess. But the error persist. I measure the voltage across the battery terminal with the battery connected. The current was measured by soldering wires to the PCB battery connector and the battery and connecting the multimeter in series.The controller won't turn on if its just battery. It will only turn on when plugged in through usb. It worked when I first replaced the battery, since it came precharged. But since it emptied and won't charge up again.
The Resistor, component circled on the left, is 1.5kThe component circled on the right is a Capacitor, it is just for decouling. You can leave it off, or toss in just about any value there from 1pf to 1uF and it'll still work the same.
That part is an Inductor, and it must be on the board for the PMIC (Power Managment Intergrated Circuit) to work correctly. If it is not broken, and the pads are still on the board, then you should be able to resolder it back on there. I'd have to see good pics of the part and the board to tell. Sometimes they can break off 'clean' and you will be able to repair it. If it has ripped off a pad from the board or the Inductor is damaged then it will be much harder to repair.
