Smart TVs age in strange ways, and the experience often slowly becomes less pleasant even if the panel itself still looks great. I found that a few focused DIY upgrades were enough to transform how mine works and make it feel like something new again. None of these projects requires buying a new television or replacing your streaming box, and most of them cost only a few dollars or use gear you may already have. Together, they breathe new energy into the hardware you already own and make daily viewing feel more modern.

Build an AI-powered universal remote

Creating a fully customizable control experience at home

A universal remote driven by a Pico W or ESP32 lets you control your entertainment system with a level of flexibility that commercial remotes rarely match. You can teach the microcontroller every infrared command your devices use and combine them in creative ways. This becomes especially helpful when you mix older hardware with newer equipment that was never designed to work together. Once the codes are captured, the remote becomes a single point of control that reflects how you use your setup.

You can integrate the device with Home Assistant to unlock features that go far beyond infrared buttons. Routines can adjust the lights, change the input, and set the volume with one voice command. Over time, you can also build custom automations that respond to specific conditions in your living room. The remote stops being a basic clicker and becomes something shaped around your habits.

Because the microcontroller is so small, you can hide it behind your TV or near your console shelf. It still sends commands clearly thanks to the infrared emitters, and the wireless connection lets you trigger scenes from your phone or tablet. This makes it an effortless upgrade, especially if you already use Home Assistant for other areas of your home. The more devices you add, the more valuable the remote becomes.

Build a server-backed media library

Bringing organized and rich media browsing to your TV

Running Jellyfin or Plex on your own server instantly improves how you navigate your movies and shows. These platforms scan your entire collection and present everything with artwork, categories, and detailed metadata. The layout stays consistent across all devices, so your TV no longer depends on a slow or outdated built-in app. It is a cleaner and more enjoyable way to explore what you own.

Your server can handle the heavy lifting, including transcoding and metadata generation. Older TVs often struggle with specific codecs or high-bitrate files, but a dedicated server eliminates that problem. The TV only receives a stream it can comfortably play, so there are fewer stutters and compatibility issues. This helps old hardware behave like something much newer.

Pairing the server with a lightweight client app on your TV completes the experience. You can use the official Jellyfin or Plex app, or install Kodi on a Raspberry Pi and connect via the appropriate add-on. Either approach delivers fast browsing and reliable playback without stressing the TV. It also keeps your library centralized and easy to expand over time.

Transform your TV using Pi-hole

Cleaning up smart TV menus for better usability

Running Pi-hole on a Raspberry Pi gives your entire home network instant protection from ads and tracking domains. Smart TVs are particularly noisy devices, and they often send analytics data and pull ads for their built-in menus. Pi-hole filters these requests before they ever reach your television, which leads to cleaner interfaces and faster loading of the home screen. Many people are surprised at how much smoother their TV feels after blocking the worst offenders.

The installation process is straightforward and does not require any complicated configuration on the TV itself. Pi-hole quietly takes over DNS for every device on your network and filters domains in real time. You can add curated blocklists targeting known smart TV ad services, and the results often appear immediately. It is one of those improvements that keeps working without needing much attention after the first setup.

Pi-hole also helps with privacy, which is something many smart TVs tend to overlook. By blocking telemetry domains, you reduce the amount of personal viewing data sent back to various vendors. This gives you more control over your digital footprint while still letting the TV operate as usual. The upgrade happens behind the scenes, but the benefits feel constant.

Turn your TV into a smart photo display

Showing meaningful memories with automatic updates

Turning your TV into a digital photo frame gives it a second role in the room, especially during times when you are not watching anything. A Raspberry Pi can run a simple slideshow script, or Home Assistant can display an entire dashboard of rotating images. It keeps your screen visually interesting and adds a personal touch that most smart TV interfaces lack. The effect works well in living rooms, bedrooms, and even kitchens.

You can link the slideshow to shared cloud albums so family members can contribute new pictures. As new images appear in the album, they show up on the TV within a few minutes. This creates a sense of ongoing connection and makes the display dynamic rather than static. The TV becomes a shared space for everyone in the home.

Scheduling the slideshow makes it even more natural. You might have it run during quiet moments of the day or only when the TV has been idle for a few minutes. You can also mix in widgets such as weather or calendar notes to make the display more practical. The project is simple to maintain and keeps your television visually interesting even when you are not watching a show.

Add dynamic ambient lighting to your TV

Enhancing immersion with color-matched LED backlighting

Installing ambient lighting with WLED or Hyperion adds a layer of immersion, making movies and games feel richer. These systems analyze the colors at the edges of your screen and project them outward through LED strips behind your TV. The glow blends into your wall, softening the viewing experience. It also helps make smaller screens feel larger by extending the image’s perceived boundaries.

A Raspberry Pi or ESP32 handles the color capture and lighting effects with impressive speed. Once configured, the LEDs respond smoothly to on-screen actions without introducing distracting delays. You can also choose from different lighting modes depending on your mood or the content you are watching. It is one of the most noticeable upgrades you can add without spending much money.

The lighting can tie into your smart home for more advanced behavior. It can turn on automatically when the TV powers up or shift to a calmer preset when the room lights dim. Because the components are inexpensive, it is easy to scale the project to fit larger televisions or more complex layouts. The result always stands out to guests and elevates the room’s overall atmosphere.

Bringing these upgrades together for real impact

These five projects show how a handful of inexpensive ideas can transform the everyday experience of using a smart TV. Each improvement targets a different weakness and turns it into something enjoyable or more polished. When combined, they create a living room setup that feels much more modern without replacing the television. Together, they help an aging smart TV feel brand new again.
