A person who fixes TVs is commonly referred to as a "TV repair technician" or simply a "TV repairman" or "TV technician." These professionals specialize in diagnosing and repairing issues with television sets, ensuring that they function properly and deliver high-quality audio and video. They possess expertise in troubleshooting electrical and electronic components, replacing faulty parts, and fine-tuning the TV's settings to optimize performance. In recent years, as technology has evolved, some TV repair technicians may also work on other home entertainment systems and electronic devices in addition to televisions.
