Thank you for the replies Mikey and Peter. It was a $200 TV from the post office so you get what you pay for& just rereading the lousy Thomson manual they are indeed inputs.
It's great that is has 3 HDMI but definitely no HDMI ARC or optical so I was looking at buying a SMART TV with all the bells & whistles
Does anyone have any recommendations for a particular brand? I was looking at TCL but other people tell me Samsung or LG?
Thank you once again
Can't find an online manual for the medion but what you're trying to do shouldn't be too hard.
First up any reference to red,white & yellow the yellow is video. red and white is audio.
Second HDMI ARC is a feature. You might still be able to plug a HDMI cable between the sound bar and the TV. You may need to set the TV menu to send sound via hdmi.
Third any audio plugs you use you may then need to set the TV audio menu to use them. Check it out.
The 3.5 headphone connection should work. If you're getting static then possibly something is malfunctioning in this area (either TV or Soundbar)
The TV has a SPDIF output. Not sure but this might be the same as optical output?
I think you may have to look at the Television closely, the RCA sockets on your TV are likely to be inputs, not outputs.
I am not at all familiar with your Thomson TV but most of the really cheap units don't have audio out unless you call the 3.5 mm headphone jack audio out. Some equipment allows you to change a setting for the headphone jack to be audio out for that application but not likely for that unit.
It is best to spend a couple hundred more and get a much better TV IMO such as a Full HD popular brand with Toslink or some other audio out.
