I know this is old but I am a newbie and have a 40” Aquavision TV which is responding only to the On/Off functions on my remote. It comes on and is stuck on a channel with subtitles and appears to be muted. It had been working tempramentally from the start... Any pointers on this site as to how I can rectify this. I did notice before that pressing buttons too quickly upon start up would interfere or sometimes stall the start up which only rectified itself after turning the power off and on... not so now of course... any help to be had here???? Thanx in advance.
