Solved! Samsung galaxy 8 tab won't charge. Changed battery and new charger cable. Did charge a little then with charger in the battery

Solution
If it won't work, even with a new battery and charger (and those are original and not aftermarket) then it likely needs to be looked at by a tech. However, if the parts you bought (especially the battery) are not OEM, then you may want to consider getting that and returning the other battery.
