Re: OEM charger, did you use a new cable AND plug adapter? Cables can go bad as well. Possible the charging port may be bad or damaged as well. Inspect it with a magnifying glass for any bad soldering, broken off jumpers, and broken pin(s). Have you replaced the charging port itself? Some tab 3 models have a port that is attached to the logic board by a (16?) pin connector. If you have one of those then replacement is EASY, otherwise you'll need expert microsoldering skills to swap out the charging port. I'm assuming OS is up to date. Good luck.
