How to Fix Subtitles Not Working or Showing on LG Smart TV

People enjoy using LG TV because it is one of the few businesses that produce both OLED and LED-backlit TVs. Compared to other companies, their OLED TVs deliver the best value and performance and have a vast selection of streaming options and excellent picture quality.

And there are a lot of reasons why people need subtitles. The first and most significant reason to enable subtitles is for those with hearing difficulties. They would not miss out on watching great quality movies and shows just because they have hearing problems.

People also use this for convenience; some of the words and conversations in the film could be difficult to hear or comprehend because the actors might have different accents.

Subtitles can also help in learning a new language. This is the best way to study a foreign language. Without that too much pressure on formal learning, you can just simply stream on Netflix and chill while on vacation and, at the same time, use it for efficient learning.

Why Subtitles are not Working on your LG Smart TV

There are factors why you do not see the subtitles on your LG TV. There may be a problem with the LG TV settings. Maybe your television has a bug.

It could also be because the show or movie you are watching doesn’t have subtitles. Or do you still need to turn the caption option on?

It could also be a temporary bug or glitch in your streaming app. And lastly, maybe the SRT (SubRip Subtitle) Files are not the same as your .MP4 file.

Do you have problems when using a USB to watch content? In this situation, be sure of the following.

  • Ensure the Subtitle and the video/movie file are in the same folder.
  • Verify that the file names are the same. (As LGTV.AVI Video File and LGTV.CAP) (LGTV.SMI)
  • To avoid confusion, keep the filename short. Make it brief if it’s lengthy (as LGTV.SMI, LGTV HD1080P.X264.AAC.Mandarin.CHS-ENG.Mp4Ba.SMI)
  • If you encounter a problem, check the subtitles’ properties or try a different caption or subtitle file.

The supported external and embedded subtitle formats for your LG TV are listed below.

External Subtitle

  • ass, ssa, txt, dcs, psb (PowerDivX), smi, srt, and sub (Micro DVD, SubViewer 1.0/2.0)

Embedded Subtitle

  • Sub Station Alpha (SSA), SRT, Advanced Sub Station Alpha (ASS), Matroska (mkv), MP4: Timed Text

Hopefully, one of these solutions has fixed your subtitles on LG TV. If all the steps above do not work, Contact LG Support. Try calling LG customer service if you need help with the previously stated steps.

Inform them of your concern, describe your problem, and request that they resolve it or provide you with ideas to fix it.
