Professional LCD/LED TV Repairing Course - Master Television Repair Skills
Television repair is one of the most profitable technical skills you can learn today. Almost every home has one or more LCD or LED TVs, and these devices develop problems regularly. Display issues, power failures, sound problems, and backlight defects are common complaints. While most local technicians simply replace entire boards or panels, trained professionals who can actually repair televisions at the component level earn significantly more and build loyal customer bases. Our LCD/LED TV repairing course teaches you complete television troubleshooting and repair from basics to advanced chip-level work.
We offer specialized training in both LCD and LED television repair technologies. Though often used interchangeably, LCD and LED TVs have important technical differences that affect repair approaches. LCD televisions use CCFL (Cold Cathode Fluorescent Lamp) backlighting, while LED TVs use LED strips for illumination. Each technology requires different diagnostic skills and repair techniques. Our comprehensive course covers both types thoroughly, teaching you power supply repair, panel testing, backlight troubleshooting, T-con board repair, mainboard diagnostics, and complete television servicing from all major brands.
Whether you want to start your own TV repair shop, work in an electronics service center, or add television repair to your existing skills, our training provides the practical knowledge you need. All courses are conducted offline at our fully equipped workshop where you work on real faulty televisions from brands like Samsung, LG, Sony, Panasonic, Videocon, Micromax, and others. You learn actual fault-finding techniques, not just theory. Our experienced instructors guide you through real repairs, teaching you the systematic approach professionals use.
The demand for skilled TV repair technicians is enormous and growing. With television prices dropping, more people own multiple TVs. When problems occur, repair is often more economical than replacement, especially for larger screens. Customers are willing to pay ₹1,500-8,000 for repairs versus buying a new TV costing ₹20,000-1,00,000. As a trained technician, you can earn ₹30,000-1,00,000 per month depending on your workload and expertise. This is not just a technical course – it is your path to a stable, profitable, and independent career in electronics repair.

They have repaired thousands of TVs from all brands and know every common fault pattern. They teach you the shortcuts, tricks, and systematic approaches that only come from years of real repair work. When you learn from someone who fixes TVs daily, you gain practical insights textbooks cannot provide. Our instructors share real customer situations, business challenges, and professional techniques that make you job-ready immediately.
Extensive Hands-On Practice with Real Faulty TVs
Theory alone cannot make you a TV repair technician. You need to physically work on televisions, open them, test components, and fix actual faults. We maintain a large inventory of faulty TVs specifically for student practice. Multiple LCD and LED TVs from different brands with various problems are available. You spend most of your training time actually repairing televisions, not just watching demonstrations. This hands-on approach builds the confidence and muscle memory essential for professional repair work.
Component-Level Repair Training
Most training centers teach only board replacement – simply swapping faulty boards with new ones. We teach actual component-level repair where you identify and replace individual faulty components. This skill dramatically increases your earning potential because you can repair boards that others replace. Component repair costs customers much less than board replacement, building loyalty and referrals. You learn to identify faulty capacitors, resistors, ICs, and other components, then properly replace them using professional soldering techniques.
