The main problem with tuners is overheating. More often, consoles with an external power supply unit (ESP) burn out. Usually, FPS is made by third-party suppliers, so it is difficult for manufacturers to control their quality. A bad UPS generates an overestimated voltage, which disables the device. A good choice in this case is a tuner with a built-in voltage regulator.
All top-end consoles have a built-in power supply unit (PSU). The WPS is a sign of a careful approach to device design. Such devices are more expensive, but they will last longer and bring more pleasure with thoughtful functionality.
How to choose a TV tuner: size matters?
The smaller the model, the more often it burns out. This is due to the fact that the components are closely spaced on a small board, so it dissipates heat worse. The larger the board, the heavier the device. In addition, there may be additional heatsinks on the board. So choose not only large consoles, but also heavier ones.
How to choose a tuner for your TV with the best functionality
A complete tuner should be able to:
- Play main video formats - AVI, MPEG-2 / MPEG-4, MKV, MP4, DIVx, images - JPEG, sound - MP3, WAV.
- Maintain a resolution of at least 1920x1080.
- Support DOLBY DIGITAL sound (AC3 codec).
- Receive a signal not only in DVB-T / T2 standards, but also in DVB-C - this makes it possible to connect to cable operators.
- Support IPTV. To use this feature, you need a Wi-Fi adapter that plugs into a USB port. With its help, the set-top box will be able to connect to your Wi-Fi router.
- Have a recording function.
- Have a programmable remote control.
