The connection port where the cable connects to the tablet is partially broken, I think. The cables fit very loose and the charge blinks back and forth ..charging not charging. I have tried many cables to be sure it is the tablet side and not the cable. Where or how can this be fixed? Thank you in advance for any information.
@eljay1250 your tablet uses a charging port board. Available at places like this and others. To get to the board you have to remove the display assembly. Use these guides Samsung Galaxy Tab S2 9.7 (2015) Repair or this video for that
