When you find that Sony BRAVIA TV can't play your video, you need to check the following aspects:
1. First, determine whether there is any problem with the file itself, whether it is encrypted, whether it is damaged during transmission, etc.
2. If video is intact, check your USB device system second. USB supported file systems are usually FAT32 and exFAT.
3. If nothing else is wrong, you should consider whether video formats are supported by Sony BRAVIA. The format here not only refers to the container format like MP4, MKV, etc., but also depends on whether the packaged audio and video encoding is supported by Sony BRAVIA.
The search results of Sony BRAVIA video format and other keywords on the Internet have no reference significance because there are many models of Sony TVs, and of course, the standards and specifications of each model are also different. Here's how to check out your Sony BRAVIA supported video formats via USB.
Step 1. Go to https://www.sony.co.uk/electronics/support/televisions-projectors, select your TV product type, and click to enter.
Step 2. Scroll down and you will find a lot of TV Models listed. You can also search through the search volume above. After finding your model, click Manuals under the model.
Step 3. Go to the Manuals directory and click on the Help Guide to open a new page.
Step 4. Click on Using the TV with Other Devices > USB devices > Supported files and formats > Videos to see the audio and video formats that your TV can support.
