Tabletl shuts down by itself. Sometimes won't turn on

@juryop ,Margaret, Could be faulty battery, charger, charge port, faulty motherboard, or corrupt app/program that is causing issue. A lot of forums feel a factory reset can fix this type of issue, read and follow the steps in the first link below if you would like to try a factory reset, all data not backed up will be lost.

Reset did not work, either the cable or charge port may be damaged. The battery, cable/charger or charge port may be faulty damaged. Look in the charge port and blow/pick out(carefully) any dust/debri that may be causing an issue also look in the port for any bent pins and straighten very carefully with a tooth pick. Try a different compatible charger/cord to see if that is the issue. If different compatible charger/cord does not fix and port looks/test good, the battery or connection could be bad, if able to clean battery connections and reconnect/install battery, still not charging battery probably faulty. If port is found to be bad/loose/damaged , this is really not a repair for the inexperienced because the charge port for your device is soldered to the mother board and the heat generated could cause further damage if not very careful. I will post a link to a tear down guide to get you inside the tablet to check the charge port/battery connection. If not wanting to do the repair yourself have a good computer/cell phone repair shop have a look and estimate repair. Good luck.

I hope this helped you out, if so let me know by pressing the helpful button.
