I have this same model tv and struggling to connect to a JBL soundbar in the sound settings. Do you have a tutorial on how to connect to an external sound device? Thank you.
I have a couple of issues with a different Hitachi tv. Could you tell me, if you press the program button and keep it pressed does it scroll through the channels? Mine used to do that and now it doesn't anymore also it reboots randomly.
This TV has a few bugs like the home screen sometimes don't work the fire stick is not recognised by the hdmi connection. Also I don't think the picture is not that good.
