32pfl4606 mute screen bug
the mute screen is an energy saving option, that allows listening to the TV channel or radio channel with the display turned off. when activated, it informs the user that pressing any button on the REMOTE will result in leaving the mute screen.
the bug: pressing a button on the display panel leaves mute screen too, so there is no way to e.g. change the volume without leaving the mute screen
for your info, the samsung TVs implement this feature properly: volume control does not leave the mute screen, either from remote or display panel buttons!
