Completely dead - PP_BATT_VCC almost 0V
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
