Hi @Levin1, 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.
I'm not quite sure that I understand your question correctly. Are you not able to use the power button to turn your display on after it has been turned off due to being inactive, or that you turned it off with the power button?
Please try and elaborate a bit and I'll do my best to assist you!
