Is there any repairs shown on internal charger in Taranis 9XD plus SE?
  I just got a new radio 2-3 days ago and everything worked fine and when I tried charging LiPo through USB LiPo voltage stays constant.
 Tried a new LiPo with different voltage before charging and that’s were it stayed for 6 hours of charging.
  So charger doesn’t work if so I’d get a voltage difference or increase out of LiPo during charging by measuring voltage out of deans plug.
  Radio still works and blue led lights up during charging as directions say but not 1/100th of a voltage increase after hours of charging with internal charger.
  I was hoping to use radio at 4th fly in but other than sending it back I would rather fix it myself if possible.
 Is there any possibilities a loose connection,cold solder joint,bridges circuit is inside radio?
  Is there any hacks or videos about internal charger.
 Unfortunately there’s not much I can find on 9XD plus SE 2019,lots of 9XD plus but no SE 2019.

Are you sure there is definitely an issue with your transmitter? Did you try contacting the.ronin like I mentioned in your other thread?

Keep in mind that if there is an issue with the USB charging circuit and you try to fix it yourself then you will void the warranty for any other problems that might occur in future. If it has a problem, better to just get it replaced by the supplier rather than risk headaches further down the line because you killed any prospect of getting repairs done under warranty for any other future issues.

I must have missed what you mentioned contacting the ronin but your right about warranty and I’ll contact theronin.
I contacted supplier and will have to wait it out.
