If you purchased this from a retail store, I’d return it. Buying electronic goods on line like old used devices , it’s buyer beware. A lot of them are out there for sale because they were problems for someone else or just extremely cheap quality. I have family member that bout MP3 players on like for less than 10.00 and they lasted a week at most.. If you saw smoke and smelled something, then I’d write this off as a lost cause.
