Hi dereza,
Welcome to Sony community!
It looks like this SVE171E13V is a non-US model, therefore, we have limited information on the specifications and parts. We suggest that you bring the unit to an authorized repair center to have them fix it for you
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
