This paper studies and analyzes the common faults of the broadcast television launch system. Firstly, the basic composition and working principle of the broadcast television launch system are briefly summarized, and the reasons for the failure of these failures are analyzed in detail. On the basis of this, the paper puts forward the actual situation of Guangdong Xinyi 732 units, and puts forward the specific troubleshooting measures, including the prevention measures of the fire failure, the repair and replacement of the separate feed line, the waterproof treatment of the water fault and the design and implementation of the lightning protection. By means of these measures, the probability of the failure of the broadcast television launch system is effectively reduced, the stability and reliability of the system are improved, and the smooth transmission and quality service of the radio and television signals are ensured.
