Sorry. I made some mistake in my previous question.
If possible, please delete it.
I actually bought LN-T3253H in 2007, but I have never seen HDTV channel with LN-T3253H before in my apartment. But recently, my friends purchased newer Samsung HDTV, and they can discover at least 4 HDTV channels. Because we are living in the same apartment, I am trying to discover HDTV channel many many times again, but I do not get anything.
What is the problem? Is it caused by lower version of firmware?
I am also trying to get the information of firmware version, but I also cannot get anything about it.
I have only above two problems.
Please help me to solve these problems.
Thanks.
