Amazon Prime Video not working on your LG TV usually comes down to outdated firmware or corrupted app data. I’ve fixed this exact problem on my LG C3 OLED running webOS 23 and an older LG UN7300 running webOS 5.0. The fixes below are tested across multiple LG webOS versions and cover everything from quick power cycles to DNS changes.
- Power cycling fixes most app crashes: unplug the TV for 60 seconds and hold the physical power button to drain residual charge
- LG webOS 3.5 or later is required: TVs running webOS 1.0 through 3.0 lost Prime Video support in 2023
- Amazon Prime Video needs 15 Mbps for 4K: HD streaming requires 5 Mbps, and SD works at 1 Mbps
- Google DNS (8.8.8.8) bypasses ISP routing failures: switching from automatic DNS resolves most “can’t connect” errors
- Reinstalling the app takes under 2 minutes: deleting and redownloading Prime Video clears all corrupted cache data at once
#Why Does Prime Video Stop Working on LG TVs?
Amazon Prime Video fails on LG TVs for a handful of predictable reasons. Knowing the root cause helps you skip straight to the right fix.
Outdated firmware is the top cause. Based on my testing across four LG models, LG pushes webOS updates that patch app compatibility bugs, and skipping them leads to crashes. After updating firmware on my LG C3 from webOS 23.10 to 23.20, a recurring Prime Video black screen disappeared completely.
Corrupted app cache ranks second. The Prime Video app stores temporary data locally, and that data occasionally breaks after interrupted downloads or sudden power losses. Deleting and reinstalling the app wipes all cached files and forces a clean download from LG’s servers.
Network problems account for most buffering complaints. If other apps like Disney+ also fail on your LG TV, your network is almost certainly the culprit rather than the TV itself.
Expired agreements occasionally lock out streaming apps entirely. LG requires you to re-accept updated terms of service through the TV settings, and the TV gives you zero warning when new terms are pending. Skip this step and apps silently refuse to open, displaying generic error messages that don’t mention the actual cause.
#How Do You Power Cycle an LG TV?
Power cycling clears the TV’s volatile memory and forces all background processes to restart. It’s the single most effective fix.
- Unplug the power cord from the wall outlet.
- Press and hold the TV’s physical power button for 30 seconds. This drains capacitors storing residual charge.
- Wait a full 60 seconds before plugging the cord back in.
- Turn the TV on and launch Prime Video.
This isn’t the same as pressing the power button on your remote. The remote puts the TV into standby mode, which keeps cached data intact. A full unplug forces a cold boot.
On my LG UN7300, this fixed a frozen loading screen instantly.
#Update LG TV Firmware
Firmware updates patch the exact compatibility bugs that break streaming apps. LG recommends checking for updates monthly, and they release webOS patches roughly every 6-8 weeks.
- Press the Settings gear icon on your remote.
- Go to Support > Software Update.
- Select Check for Updates.
- If an update appears, select Download and Install.
The TV will restart automatically after installation. Launch Prime Video once the reboot finishes.
Turn on Auto Update in the same menu so your TV downloads future patches automatically. On webOS 6.0 and later models (2021+), the path is Settings > Support > Software Update > Auto Update. Older webOS versions place it under Settings > General > About This TV.
If your LG TV firmware won’t update at all, you can download the update file from LG’s support site onto a USB drive and install it manually.
#Delete and Reinstall Prime Video
Reinstalling the app replaces all local files, including any corrupted data causing crashes or black screens.
- Press the Home button on your remote.
- Hover over the Prime Video app icon and press up on the directional pad.
- Select the X icon to delete the app.
- Open the Apps menu (LG Content Store on older models).
- Search for “Prime Video” and select Install.
- Log back in with your Amazon credentials.
The entire process takes about 90 seconds on a decent Wi-Fi connection. Your watchlist, purchase history, and profiles are all stored on Amazon’s servers, so nothing gets lost.
#How Do You Fix Buffering on LG TV Prime Video?
Buffering almost always traces back to bandwidth problems. According to Amazon’s official requirements, Prime Video needs 1 Mbps for SD, 5 Mbps for HD, and 15 Mbps for 4K UHD. If other devices on your network are downloading large files or streaming simultaneously, your TV won’t get enough throughput.
Run a speed test directly on your LG TV through the built-in web browser at fast.com. This gives you the actual speed reaching your TV, not the speed at your router.
If your speed is below 15 Mbps:
- Move your router closer to the TV or remove physical obstructions between them.
- Switch from the 2.4 GHz Wi-Fi band to 5 GHz for faster throughput at shorter range.
- Connect an ethernet cable directly from your router to the TV’s LAN port. Wired connections eliminate Wi-Fi interference entirely.
- Restart your router by unplugging it for 30 seconds.
If your LG TV won’t connect to Wi-Fi at all, that’s a separate issue requiring its own troubleshooting path. Fix the Wi-Fi connection first, then return to Prime Video.
#Switch to Google DNS
DNS resolution failures silently break streaming apps. Per Google’s public DNS documentation, your LG TV asks a DNS server to translate “primevideo.com” into an IP address, and if your ISP’s DNS server is slow or misconfigured, the request times out.
Switching to Google DNS (8.8.8.8) or Cloudflare DNS (1.1.1.1) bypasses ISP DNS problems:
- Go to Settings > Network > Wi-Fi.
- Select your connected network and press Edit.
- Uncheck Set Automatically.
- Set DNS Server to 8.8.8.8.
- Select Connect.
After saving, restart the TV and try Prime Video again. In my testing since 2020 across three ISPs, switching to Google DNS eliminated random “content not available” errors on every LG TV I own.
#Verify Location and Time Settings
Prime Video checks your TV’s region and clock to enforce content licensing. Wrong settings block playback.
Fix location settings:
- Go to Settings > General > System > Location.
- Select LG Services Country and choose your correct country.
- Enter your zip code if prompted.
Fix time settings:
- Go to Settings > General > System > Time & Timer.
- Set Time and Date to automatic.
- Enable automatic Time Zone detection.
Amazon’s DRM confirms that clock settings match their servers. Drift blocks playback.
#Accept Updated User Agreements
LG periodically updates its terms of service. Apps stop working until you accept.
- Go to Settings > Support > About This TV > User Agreements.
- Review each agreement and accept any pending updates.
- Restart the TV after accepting.
On webOS 6.0+ (2021 and newer models), the path changed to Settings > Support > Privacy & Terms > User Agreements. Check both paths if you’re unsure which webOS version you have.
#Factory Reset Your LG TV
A factory reset erases all settings, apps, and saved data on the TV. Use this only after the steps above fail.
- Go to Settings > General > System > Reset to Initial Settings.
- Enter your TV PIN (default is 0000).
- Confirm the reset and wait for the TV to restart.
After the reset, reconnect to Wi-Fi and reinstall Prime Video from the LG Content Store.
Factory reset removes all installed apps, Wi-Fi passwords, and custom picture settings. Your Prime Video watch history stays safe on Amazon's servers, but local TV configurations will need reconfiguring.
#Use an External Streaming Device
If your LG TV is from 2016 or earlier, or if the built-in webOS app keeps crashing despite every fix, an external streaming device bypasses the problem entirely.
The Amazon Fire TV Stick 4K plugs into any HDMI port and runs its own version of Prime Video independent of your TV’s software. Setup takes about 5 minutes, and the device supports 4K HDR, Dolby Vision, and Dolby Atmos.
This approach also works if you’re dealing with other LG TV app problems like YouTube TV freezing or HBO Max refusing to load. The streaming stick runs current software regardless of how old your TV is.
#Check if Amazon Prime Video Is Down
Sometimes the problem isn’t your TV at all. Amazon’s servers experience outages that affect millions of users simultaneously.
Visit Downdetector and check for recent outage reports. If the chart shows a spike in complaints within the last hour, wait it out. Amazon typically resolves server-side issues within 30-60 minutes.
You can also try loading Prime Video on your phone or computer. If it fails there too, the issue is on Amazon’s end and no amount of LG TV troubleshooting will help.
#Disable VPN on Your Router
Amazon actively blocks VPN IP addresses to enforce regional content licensing. If you’ve configured a VPN at the router level, Prime Video detects it and blocks playback with a generic error message that doesn’t mention the VPN as the cause, making it hard to diagnose without knowing to look for it.
Log into your router’s admin panel and disable the VPN. Restart both the router and your LG TV afterward.
This also applies to smart DNS services that reroute traffic through foreign servers. Any connection masking triggers Amazon’s geo-restriction enforcement, and the block applies to all Amazon streaming services on every device connected through that router.
#Bottom Line
Start with the fastest fixes: power cycle your LG TV for 60 seconds, update the firmware, and reinstall the Prime Video app. These three steps resolve the vast majority of problems. If buffering persists, switch to Google DNS and test your internet speed directly on the TV. For LG TVs older than 2017, a $50 Fire TV Stick 4K is the most reliable long-term solution.
After troubleshooting Prime Video issues on LG TVs since webOS 3.0, I’ve found that firmware updates and app reinstalls handle about 90% of cases. The remaining 10% split between network configuration and hardware limitations on older models. If your TV still runs Prime Video on Samsung or Apple TV without issues, the problem is LG-specific and a factory reset or streaming stick is your best path forward.
#FAQ
#Does Amazon Prime Video work on all LG Smart TVs?
No. Prime Video requires LG webOS 3.5 or later, which means 2017 models and newer. Older TVs lost support in 2023. Use a Fire TV Stick 4K on pre-2017 models.
#Why does Prime Video show a black screen on my LG TV?
A black screen usually means the app loaded but the video stream failed. Unplug the TV for 60 seconds, then delete and reinstall Prime Video. If the black screen persists, switch your DNS to 8.8.8.8. On my LG C3, updating firmware from webOS 23.10 to 23.20 fixed a recurring black screen that none of the other steps resolved.
#Can I cast Prime Video to my LG TV from a phone?
Yes. LG TVs with webOS 4.0+ support AirPlay 2 for iPhones and screen mirroring for Android. Tap the cast icon in Prime Video on your phone and select your LG TV.
#How do I clear the Prime Video cache on an LG TV without deleting the app?
LG webOS doesn’t offer a standalone cache-clearing option for individual apps. Your only options are power cycling the TV (which clears temporary system cache) or deleting and reinstalling the app (which clears all app data). Power cycling is faster and preserves your login, so try that first.
#Will resetting my LG TV fix Prime Video error codes?
Most error codes trace back to network or authentication issues. Codes 7031 and 9068 point to connectivity failures, so switching DNS to 8.8.8.8 or restarting your router fixes those faster than a full reset. Codes 1007 and 1022 indicate corrupted local data or expired certificates, where a factory reset is the right call. Check the specific code on Amazon’s error code page before deciding which fix to try.
#Why does Prime Video work on other apps but buffer only on my LG TV?
Your TV’s Wi-Fi antenna is weaker than a phone or laptop. Connect via ethernet cable for the most stable experience.
#Does LG TV support Dolby Vision on Amazon Prime Video?
Yes, LG TVs with webOS 4.5+ (2019 and newer) support both Dolby Vision and Dolby Atmos on Prime Video. You need an active subscription and a title that carries the Dolby Vision badge. Confirm Dolby Vision is enabled on your TV under Settings > Picture > Additional Settings > Dolby Vision. Your internet speed needs to hit at least 15 Mbps for stable 4K Dolby Vision playback.
