At approximately 9:00 p.m. on February 13, a partial broadcast interruption occurred on Hunan Satellite Television (Hunan TV), resulting in a temporary black screen on viewers’ screens.
According to widespread reports from viewers, the incident took place shortly after the finale of The Story of Minglan concluded and during the airing of Against the Flow. Multiple users shared images online showing that Hunan TV’s signal had briefly gone black.
 

The timing of the disruption drew particular attention, as the finale of The Story of Minglan, starring Zhao Liying, achieved an exceptional peak rating of 3.5958%, among the highest nationwide. With such a large audience, the “Hunan TV black screen” quickly became a trending topic on Weibo, sparking heated discussion across social media.

Shortly after the incident, AsiaSat issued a statement confirming that the ChinaSat 6A (Zhongxing-6A) satellite had suffered a major malfunction around 21:10, causing all transponders to cease operation and resulting in a widespread signal outage. The failure affected multiple broadcasters, including Hunan TV.

According to AsiaSat’s follow-up announcement, normal signal transmission was restored by 21:35. Preliminary assessments indicated that 10 standard-definition channels and 22 high-definition channels were affected during the outage.
 

The root cause of the ChinaSat 6A satellite malfunction remains under investigation and will be officially disclosed following further technical verification by relevant authorities. Reports from various regions indicate that broadcasters responded with different contingency measures—some switched to alternate feeds, others displayed subtitles, while a few continued to experience intermittent disruptions.

This incident served as a critical stress test for broadcast transmission security and emergency response preparedness across the industry. It underscored the importance of well-rehearsed operational protocols, prompt on-site decision-making, and robust backup mechanisms.

As industry professionals noted, broadcast networks maintain 24-hour technical staffing to monitor hundreds of live channels and on-demand services. In the event of a sudden transmission failure, immediate on-site response is crucial. Without engineers physically present in the control room, recalling staff after hours could take 30 minutes or more—highlighting the ongoing challenge of recruiting and retaining qualified technical personnel in the broadcast sector.
The incident further demonstrates the persistent challenges in ensuring secure and stable broadcasting, emphasizing the need for enhanced redundancy and automatic/manual switching mechanisms in both optical fiber transmission and satellite links. Engineers will also be responsible for subsequent tasks such as verifying replay and on-demand service data.
As this event reminds us: broadcast safety is of paramount importance—vigilance must never waver.
