I have sound through the sound box but no picture on hdmi1

Solution
ARC has to be turned on in the TV menu to work. Check the TV manual.
If you have connected the soundbar via HDMI-ARC then you can't use that input for anything else unless the soundbar has an HDMI input; then you would need to connect your source there. If it doesn't and you need that input then use the audio output of the TV instead.
