I have absolutely no response from controller. I checked the battery and 12 pin ribbon connector voltage on the board. There ain’t any, but the micro usb rort is functional and has voltage on its dc and gnd pins. Board version is JDM-030. The problem seems to be both with usb board(jds-030) and battery. If you have any ideas on what else should I check on the board, please tell me, preferably with photo instructions to which pin on the motherboard I should connect multimeter probes to confirm if the main board is alive and does not need replacement.
And aslo, my multimeter is the cheapest trash, yet it shows the voltage of a regular alkaline battery and on the microusb port, so it is definetely not the problem.
