Samsung Galaxy Note 3 SM-N900A Phone will not turn on. When we plug the charge cord in there are no lights indicating it is charging. We have tested the charge cord on other devices, so we know it is good. We have removed the battery for several minutes and then replaced it to no avail. Not sure where to go from here to diagnose this. Thanks in advance!
try to enter download mode or recovery (google) if you can’t access these crack your phone open and try to reconnect every cable also check the boards for damage junk or whatever dosen’t look normal does it respond anyhow if you power it up? vibrates? sound comes out? try to check the baterry (multimeter >3.2v<4.2v) (or on other phone) since SGN3 can’t boot of charger there are Million things that could &&^& itself up if you have 2nd SGN3 (friend of family maybe?) you could check all boards (just switch the boards arround and check which one the problem is anything that i can think of may be some thermal damage (overheat) or maybe some junk is inside phones just don’t die for no reason it could be as easy as battery and as hard as broken trace after your research let me know what you found (if board damage -> post pictures) oh and btw. try to check your boards with 10x or so lens (50x would be awesome but i don’t think you have any (i have only 30x))
