Smart TVs: Every Fix in One Place

On a Samsung TV, check Settings > Support > Software Update first. On an LG TV, it's Settings > All Settings > General > About This TV > Check for Updates. Outdated firmware is one of the most common causes of weird app behavior on smart TVs, so this step genuinely matters more here than on most streaming sticks.

Once you're updated, connect to Wi-Fi (or Ethernet if your TV has a port and it's within reach), and you're ready to start adding apps from the built-in store.

On Samsung TVs, open Smart Hub and search for your licensed provider's app. On LG, it's the LG Content Store. Both work basically the same way as any app store — search, select, install, and it lands on your home screen ready to use.

One honest heads-up: built-in smart TV app stores are generally more limited than what you'd find on a Fire TV Stick or Roku. If your provider isn't listed, that's genuinely common — see the next question for what to do about it.

This happens more than people expect — built-in smart TV platforms simply don't have the same catalog size as dedicated streaming devices. First thing to check: does your provider's phone app support casting to your TV, or AirPlay if you've got an Apple device and a compatible TV? That sidesteps needing a native TV app entirely.

If that's not an option either, the honest, simplest fix is plugging in an external device like a Fire TV Stick or Roku — their app catalogs are considerably bigger, and it takes about five minutes to set up alongside your existing TV.

Same starting point as any remote: fresh batteries, even if the old ones "seem fine." Beyond that, check whether anything's blocking the direct line between the remote and the TV — some newer smart remotes use Bluetooth and don't need line of sight, but plenty of basic ones still rely on infrared and need a clear path.

If it's a Bluetooth-style smart remote and it's still unresponsive, unplugging the TV itself for about 60 seconds and plugging it back in often forces a fresh re-pair on startup.

Start with the router (unplug 30 seconds, plug back in), then dig into your TV's network settings, forget the saved Wi-Fi connection, and reconnect from scratch with the password typed carefully.

Built-in smart TV Wi-Fi antennas tend to be weaker than dedicated streaming sticks, especially on older models. If your TV has an Ethernet port, it's genuinely worth running a cable if the TV's anywhere near your router or a switch.

Here's a useful diagnostic: if a separate Fire TV Stick or Roku on the exact same Wi-Fi network streams smoothly but your smart TV's built-in apps buffer constantly, that's a strong sign the TV's internal Wi-Fi radio just isn't as capable — this is a known limitation on a lot of smart TV models.

If Ethernet is available, use it. If not, a mesh Wi-Fi extender placed near the TV can noticeably improve things without needing to run a cable across the room.

Smart TVs generally have less processing power and memory than a dedicated streaming box, so having several apps open in the background (accessible through the recent-apps menu) can genuinely slow things down. Close anything you're not actively using.

If one specific app keeps crashing, uninstall and reinstall it from Smart Hub or the LG Content Store — this is the smart TV equivalent of clearing an app's cache and resolves a good chunk of these issues.

Since built-in apps run natively on the TV (not through an HDMI input), if picture's missing here specifically, check the TV's picture settings menu for anything unusual, like a picture mode that got accidentally switched. A quick power cycle (unplug the TV for 60 seconds) also resets a surprising number of display glitches.

For sound, check whether the TV's audio output setting got switched to an external soundbar or receiver you're not actually using right now — this is one of the most common "no sound" causes on smart TVs specifically.

A full power cycle — unplug the TV for a full minute, then plug it back in — clears out background clutter and fixes a lot of general sluggishness on smart TVs, more so than on newer streaming boxes.

If it's still slow after that, be honest about the TV's age: smart TV processors from several years ago just weren't built for how demanding today's apps have gotten. In that case, a modern Fire TV Stick or Roku plugged into an HDMI port often runs circles around the TV's own built-in smarts.

Manufacturers don't support smart TV software forever — after a few years, older models often stop receiving new app versions entirely, even if the TV's picture quality is still perfectly fine. If your apps feel stuck in time or a provider says your TV's app is no longer supported, that's very likely what's going on.

The good news: your TV still works great as a display. Just add a current-generation Fire TV Stick or Roku to an HDMI port, and you're instantly back on fully supported, up-to-date software without replacing the TV itself.
