Why are the channels not showing on my TV?
Updated in September 2026. This is still one of the most-read articles on our blog, because the underlying problem has not changed: if your TV has stopped showing channels, it is almost always due to a pending retune after a frequency change, a tuner without HD, or a fault in the aerial or cable. The order of checks we recommend: first, retune from the television's menu; if channels are missing, check the aerial cable connection and the amplifier, if there is one; and if the television is older than 2014 and has no HD tuner, an external DTT HD receiver (€20-30) still solves the problem without changing your TV. Any television we sell today tunes in to current DTT without any problem. If you do decide to replace it, we have published a complete guide covering screen size according to the distance from the sofa, the real differences between QLED, NanoCell and Mini LED, and specific models with prices: Which television to buy in 2026. Please remember that we sell televisions and deliver them in our own van only in the Valle del Almanzora, Levante Almeriense and Los Vélez; just ask and we will tune your new one before delivering it.
The Age of High Definition: A New Way of Watching Television
Since 14 February, the way we enjoy television in our homes has changed significantly. The switch from standard-definition (SD) to high-definition (HD) television is not just a technical improvement; it is a revolution in the viewing experience that immerses us in a world of clarity, colour and detail like never before.
The End of an Era: Goodbye to Standard-Definition Television
Until recently, standard-definition (SD) television was the norm in our homes. However, technological advances and the demand for higher picture quality have led to a global shift towards high definition (HD). This means that, since the 14th, SD television channels are no longer broadcast, and only televisions with HD tuning capability can receive the new high-definition signals.
What Does This Switch Mean for Viewers?
The switch to HD means that, to keep enjoying your favourite programmes in the best possible quality, your television must be compatible with the HD signal. This could be a challenge for those who own older televisions without built-in HD tuners. But it is not all bad news; there are practical, affordable solutions to this challenge.
External DTT HD Tuners: An Effective Solution
At Híper Ocio we understand how important it is to adapt to change without having to invest in a new television. That is why we offer external DTT HD tuners, which allow any television, however old, to receive and display high-definition signals. These devices are an affordable, efficient solution for anyone who wants to update their television set-up without the cost of replacing it entirely. Prices are between 20 and 30 euros and installation is very simple.
HD Televisions at Affordable Prices: The Perfect Opportunity to Upgrade

High Definition: More Than Just a Better Picture
The switch to high definition not only significantly improves picture quality, with higher resolution, more vivid colours and deeper contrast, but also makes watching television a more immersive and detailed experience. It is a change that goes beyond technology; it is a new way of connecting with the content we love.
