Prime Video App

In fact, there are several troubleshooting steps outlined in this guide you can try yourself to resolve issues with the Prime Video app not working on your LG TV. The solutions range from simple steps like restarting your devices or checking for software updates to more advanced fixes like performing a factory reset on your TV or deregistering your LG TV from your Amazon account.

One of the first things to check is your Internet connection and Wi-Fi router to ensure your LG TV has access to the network resources it needs to run streaming apps. You should also make sure you are using the correct login credentials for your Prime Video subscription in the app. Outdated or corrupted software including your TV firmware and the Prime Video app itself can often cause streaming apps to malfunction, so updating or reinstalling them may do the trick.

If software-related issues seem to persist, you may need to reset your TV to factory settings to refresh the entire system. As a last resort, you can try a hard reset of your TV to reboot the operating system. However, this should only be done if recommended by LG to avoid potential damage or voiding your warranty.

Overall, the majority of Prime Video issues on LG TVs are minor software glitches or connectivity problems that can typically be resolved with some basic troubleshooting at home. But for hardware issues or more major software malfunctions, you will need to get technical support from LG to diagnose and repair the problem. 

With patience and persistence in working through the step-by-step fixes, you can usually get your Prime Video app back up and streaming your favorite shows in no time.
