When multiple streaming apps like Prime Video and Netflix stop working at the same time on your LG 75" Class 84B Series QNED evo AI Mini LED 4K Smart webOS TV (2026) Model # 75QNED84BUA, it is almost always caused by a temporary system glitch in webOS, an outdated system clock, or a network handshake error. A true cold boot clears out the corrupt temporary data causing the apps to crash. 1. Unplug the TV's power cord directly from the wall outlet or power strip. 2. Leave it unplugged for a full 60 seconds. 3. While it is unplugged, press and hold the physical Power button on the bottom edge of the TV frame for 15 seconds to completely drain any residual electrical current. 4. Plug the TV back in and turn it on. Test Prime and Netflix immediately. If the cold boot works but you want to stop this from happening again, you should disable LG's instant-on setting. This setting prevents the TV from ever truly shutting down, which eventually clogs up the system memory. Go to Settings (Gear Icon) > All Settings > General > System > Additional Settings > toggle Quick Start+ to OFF. Streaming platforms use encrypted security certificates to stream copyrighted movies. If your TV's clock is even slightly out of sync with the streaming servers, Netflix and Prime will automatically block the connection. 1. Go to Settings > All Settings > General > System > Time & Timer. 2. Look at the current date and time. If it is wrong, toggle Set Automatically to OFF and manually enter the correct date, time, and time zone. 3. Turn Set Automatically back ON so it stays synchronized. Sometimes the default network routing from your internet provider blocks communication to specific app servers. Forcing the TV to use a public DNS often clears this right up. 1. Go to Settings > All Settings > General > Network. 2. Select your active connection (Wi-Fi or Wired) and choose Advanced Wi-Fi Settings (or Other Network Settings). 3. Click Edit and uncheck the box that says Set Automatically. 4. Scroll down to the DNS Server field, delete whatever numbers are there, and type in 8.8.8.8 (this is Google's secure public server). Click Connect. If the system fixes above fail, you will need to completely wipe the corrupted application files and pull clean versions from the LG server. 1. Press the Home button on your remote to bring up the app launcher bar. 2. Scroll all the way to the right side of the bar and select the Pencil icon (Edit App List). 3. Move the cursor over to Netflix, press the Up Arrow, and click the Trash Can icon to uninstall it. Do the exact same thing for Prime Video. 4. Once deleted, open the Apps app (LG Content Store) on your home screen, search for both apps, and reinstall them fresh...^Ivan.

Hello, there! Thank you for sharing your question with us about the LG TV (75QNED84BUA). When mounting with the 300 × 200 mm VESA pattern, the correct specification is to use M6 screws. Standard installation requires a screw engagement depth of about 10 mm to 12 mm into the back of the TV, which ensures the mount is secure without damaging the threaded inserts.

You must include the remote, stand, power cord, and any other included accessories, and the TV should be in like-new condition with its original packaging to avoid potential deductions or denial of the return...^Ivan.
