luck gone.battety is ok,hdmi and monitor is ok.but the question is here. I looking for error .Disconnect everything from the system board, then remove the battery and leave for 30 minutes ... re-fit battery and and try again. If necessary I would test the HDMI and monitor by running another source through the HDMI, something like a DVD player or my android box, that will eliminate that potential issue. Good luck.
