I have a 42 inch Micromax UHD TV and trying to connect my Mitashi 5.1 Speakers to the same. TV doesn't have a headphone jack. I am able to connect speakers with set top box through the red and white cables, but when connecting tv to speakersthrough the same wire I am not getting any sound.
This looks like a TV capable of stereo sound. Left and right are red and white. I am not seeing 5.1 capabilities here.
Because you aren't getting sound I would look to the TV's settings. A TV can be set to push sound through its own speakers or through one of its other outs. Some do this automatically. IThe same way a TV's video input may need to be selected so to might the sounds output need to be changed. am however not seeing any benefit to connecting this to a 5.1 sound system.
