Hi, I’m currently repairing an SE which is completely dead. No vibration when plugged in, nothing. It didn’t have an accident, crash, water, etc., it pretty much died by itself. I checked if PP_BATT_VCC is shorted but it’s fine. However when I connect the battery and measure PP_BATT_VCC at TP02, my Multimeter shows 0.28V. When I plug the charger in it drops to 0.26V. Is there anything I can check out easily with these findings? I don’t have a microscope so if it’s too complicated/tiny I’m probably finished here… Thanks for your help! Jakob
Dead phone could be Vcc_main short or tristar failure. I have also seen spontaneous shorts on the se model and will need board level work.
The Red indicated caps will VCC_ Main top side of board if you prob them In resistance mode you you should get OL in one side if not you have a short.
