Is this tv a smart tv?

What model is the tv and what model is the soundbar? Trying to connect via cable or bluetooth?

have you looked in the owner's manual ?
Support LED TV UN40H5203AF Samsung TVs
don't know if this the right one for your set, I think the 40" series all have the same manual. I couldn't download it myself. Also on that webpage you can 'chat' to a Samsung rep. who should be able to give you better directions to the correct instructions

Good early Morning to you . This photo is of the remote that belongs to my Samsung smart TV.. Do you see the colourful button in the middle, that is the smart hub. Try going into menu, there choose Support, once there choose Contact Samsung. There you will find all information about your tv. Hope this helps, Kolbr?n

Or email Samsung or call customer service. They will need make model probably serial number.

Same exact thing going on with ours !!! Same model !

you will probably need to replace the whole tv as that mabe the cheapest way sorry

sound like you have samsungs dlp white spots plague, which just gets worst. samsung are aware of the problem, so you need to get in touch under the warranty.

No it may mean that you need a new tuner

Hi my name is Roety,
I can help you with your issue ,
If the line is present on all inputs, and effects the TV menu you most likely need a new screen.
You can try changing buffers, reseating cables.
