A:AnswerI discovered some things about the on/off button. Press the button to turn it on, press it several long seconds to turn it off; press it quickly while tv is on to bring up the input menu (which doesn't seem to give any real ability to access the menu or make menu selections. )
A:AnswerNo I don't believe there is a button for volume without the remote and to be honest I cannot turn it on and off without the remote even though it appears like you might.
