Hi @assooma, sorry to hear about this. 
I have translated your question to English as this is an International forum, please post any replies in English and it will be easier for me and other users to assist you.
If you have done the troubleshooting available and it didn't resolve the behaviour, please get in touch with your Local support team and they will either arrange a repair for you, or inform you of the closest authorized service centre, based on your location.
Let me know how it goes!
