Hi, I have a Canon 760d I've bought from Ebay with no power issue, with fully charged battery it shows no signs of life, after opening it I don't see any signs of water damage, nothing is overheating on motherboard nor DC powerboard Battery door switch and SD card switch test ok, only thing I've found is that connector in upper right corner (white connector with black wires) thats going from DC powerboard to motherboard mesures 0v on every pin...

is that normal or something got fried... can someone help me with diagnosing that... Thanks
Edit: After randomly voltage testing some components on the motherboard and DC powerboard (see photos) motherboard recives voltage on some points and steps it down, but still nothing on displays.... Tried with dummy battery so I can connect volage meter to see if it draws some current, sadly 0.00A, working camera draws from 0.03 - 0.11A in standby (0.03A when switched off) and 0.25 - 0.39 when display is on or taking pictures...
(Here are marked points where I tested voltage in refference to ground)

After some more testing with dummy battery and power supply strange things happening: I managed to get some voltage on that connector that was 0v on every pin (1st photo in post), it was 1.2v and it started drawing 0.11A manage to get it by turning power supply off and back on so I'm not even touching the camera, most of the times nothing like before, but roughtly every 10th try it shows voltage and starts drawing current I can replicate it by turning power supply on and off 10 more times... does someone know could it be loose BGA chip somewhere and how to test it?
