Television signal in Cuba suffers a blackout lasting one hour.

The television signal in Cuba experienced a one-hour blackout on Sunday night during the broadcast of the crime series "Tras la Huella." The incident did not affect the radio signal.

"Users from different provinces of Cuba have reported the loss of digital and analog signal during the broadcast of the television program 'Tras la Huella.' The high-definition (HD) channels were not affected. Radio continues to operate without issues," reported the official media outlet Cubadebate.

The incident was caused by "technical problems" that were not explained by the authorities and resulted in a 59-minute blackout in the television signal.

"The technicians from Radiocuba and other specialists are working to resolve the interruption at a line head," said Ariadne Plasencia, president of the Business Group of Informatics and Communications, on her social media.

According to the company Radiocuba, the disruption was caused by malfunctions in the operation of a technical device associated with the process of transmitting the television signal.

Finally, the standard signal for digital terrestrial television was restored after an hour. HD digital television services remain on the air, as well as the analog television service, explained the responsible company, which offered "apologies for the inconveniences caused."

In July 2023, the island's authorities announced to members of the National Assembly of Popular Power (ANPP) that Cuba would turn off analog television nationwide in 2026.

The transition process from analog to digital television in the central region will take place this year, while in the eastern region it will be in 2025 to complete the shutdown in 2026, reported the Minister of Communications, Mayra Arevich Marín.

In September 2021, the Cuban government announced that three months later it would begin the analog blackout in the western region, from Pinar del Río to Matanzas, but for reasons that were not explained, it was postponed to March 2022.

However, the process was postponed again until September and then to December 3, 2023.
