Doesn't turn on but flashes when charging

Hi there, I've had my beats for around 2 years now, yesterday at 7pm I was using them perfectly fine with no problems at all, and then when it came around 11pm it turned on but then shut down after a few seconds, when I put it in charge it shows 3 bars and one flashing so it's definitely not dead, and occasionally it will turn on but turn off instantly, I have tried the factory reset thing so if anyone is having the same problem or has any solutions please reply
