Mac book air is not turning on and getting cricket noise when press power button

My Mac book is not turning on when pressing power button . I can hear a cricket sound when ever I press power button. Initially it was turning on when I do SMC reset . But now power is full and getting green light when I plugin power cable. So if I do SMC reset now , I couldn't see the flickering from Amber to green . Now it's not working after SMC reset. Suggest me some solutions to turn on mac book air .
