I don't know of a way, since I can't speak for the features of that specific model. Please try reaching out to the Samsung customer service center in your region for further assistance.
I can only assist here with U.S. models. Sorry.
My EPG time is not correct and timezone is not exist in my tv menu. Also my autotime is not correct like EPG and I must set my tv time manually.
Is there any way to change my timezone for EPG?
