I think I have about the same problem as you.
To start TV :
Click "MY TV" -> "Channel" -> choose one channel - nothing happens -> choose another channel - now the TV starts and I get picture and audio.
To change channel:
Change channel takes about 2-10 sec. Sometimes I have to jump between two channels to kickstart the TV on the new channel.
