Wont turn on or charge

@brendankkkk could be an issue with the charging cable , the charger or the charging port. Try a different charger/cable. Clean the charging port with a few puffs of compressed air or similar. Check the port for any broken or bend pins. If all of that won’t make a difference, replace the battery next. Once you have that done see what you get. Check the motherboard for any damaged looking components and post some good pictures of your boards with your question so we can see what you see.
