Do i need a set top box for my new samsung 70inch 6 series uhd tv

Unfortunately, most TVs only support closed captions on the RF (OTA or analog cable without a set-top box) input. For other sources, the captions are enabled at the source device or app.

The Samsung Series 8 UA65TU8000KXXS does support some subtitled files from the USB drive. However, the support is limited to select subtitle and video formats. What is the format for these videos? See page 134 of the E-manual for details; the menu section on the subtitles is shown starting on page 222.

The manual for this model is available on the product page: https://www.samsung.com/sg/tvs/uhd-4k-tv/tu8000-65-inch-crystal-uhd-smart-tv-ua65tu8000kxxs/ . The current link to the manual is https://downloadcenter.samsung.com/content/UM/202208/20220802172628638/NIKDVBADT-3.2.0_EM_NIKE_ASIA_ENG_220110.0.pdf .

I hope this helps.

(VLC can support a number of caption file types. See https://www.rev.com/blog/resources/how-to-add-captions-and-subtitles-to-vlc-media-player-videos-and-movies . There is also a plugin that lets the program find subtitle files automatically. One or both of these is probably why the video captions work on VLC for Android.)

Is the sky box connected directly to the TV with a HDMI cable? If so then the HDMI cable could be poor quality or faulty!
