Hi Vaiodamario,
Welcome to Sony Community!
We're sorry to hear about this. Try to remove the battery, press and hold the power button for 15-20 sec (without plugging it in). Put the battery back then turn it back on. Here is another link for additional troubleshooting, https://us.en.kb.sony.com/app/answers/detail/a_id/34849/c/65,66/kw/no%20boot
We kindly recommend visiting our Sony Global Web site for information on contacting the Sony Support Center in your region at http://www.sony.net/SonyInfo/Support/.
Regards,
Jen
