The global television market has undergone a radical transformation over the last decade. As we move further into the era of 4K, 8K, and OLED technologies, the demand for sophisticated OEM LCD TV power supply circuit diagrams has surged. In today's industrial landscape, the power supply unit (PSU) is no longer just a transformer; it is the heartbeat of the display device, responsible for energy efficiency, panel longevity, and thermal management.
From the bustling electronics hubs in Shenzhen to the emerging assembly lines in India and Southeast Asia, factories are seeking reliable suppliers who can provide not just hardware, but integrated circuit diagrams that comply with international safety standards like UL, CE, and RoHS. The global supply chain has shifted toward "Three-in-One" integrated boards—combining the power supply, LED driver, and TV mainboard into a single PCB—to reduce manufacturing costs and slim down TV profiles.

Sichuan Junhengtai Electronic Appliance Co., Ltd. was established in 2005 and is located in Chengdu, Sichuan Province, China. It is an enterprise focusing on the production and sales of LCD TV accessories and home appliance accessories. The company warmly welcomes customers at home and abroad to cooperate with us and create a better future together. We are committed to providing customers with high-quality, cost-effective products with excellent product quality and reasonable prices. The company continues to innovate and improve products and services to meet customer needs and market changes.
Since its establishment, the company has adhered to the business philosophy of “Integrity, Perseverance and Steady development”. With years of accumulated technics and experiences, high-standard quality management system, excellent marketing ability and perfect after-sales service system, it has won high accolades from the customers.
Modern circuit diagrams focus on minimizing "Standby Power Consumption" to meet Energy Star requirements globally, reducing environmental impact.
The move toward "All-in-One" boards simplifies the assembly process for factories, allowing for faster production cycles and easier troubleshooting.
New designs incorporate smart chips that protect circuits against voltage spikes, surges, and overheating, specifically for markets with unstable power grids.
As OEM factories, we stay ahead of these trends by utilizing high-frequency switching power supply (SMPS) technologies. Our circuit diagrams are optimized for thermal dissipation, ensuring that even the most compact 32-inch or 55-inch smart TVs remain cool and durable over years of heavy use.
Exports to hundreds of countries, our main focus includes Southeast Asian and African countries, such as India, Bangladesh, Indonesia, Cameroon, and more. In the future, we will continue to enrich our products and optimize supply chain costs.
The company has a professional R&D team and after-sales service team, which can provide professional technical support and services for complex circuit diagram implementations.
The company has formed a good communication mechanism with customers, and can respond to customers' needs and questions in a timely manner, ensuring zero downtime for your production line.
The company strictly follows the ISO9001 international quality management standard for production and quality control to ensure every power board meets rigorous testing.
Global procurement for LCD TV power supply components requires a partner who understands regional differences. For instance, in the Indian market, power supplies must withstand wide voltage fluctuations. In African markets, cost-efficiency and repairability are paramount. Our OEM factory provides customized circuit diagrams that cater to these specific local needs.
Application Scenarios:
Our product line includes various types of products such as power modules, LED TV motherboards, and LED drive power supplies, meeting diverse customer needs.
Using high-quality materials and advanced production technology, our products offer high efficiency, low power consumption, and extreme stability.
Our products have passed a number of certifications, such as CE and FCC, operating stably in various environments and usage occasions.
As a leading China factory based in Chengdu, we offer unique strategic advantages. Chengdu is a major hub of the "Belt and Road Initiative," providing us with superior logistics via the Chengdu-Europe Express Rail, which drastically reduces shipping times to Central Asia and Europe.
By partnering with Sichuan Junhengtai, you gain access to the massive Chinese electronics ecosystem. We source premium capacitors, ICs, and transformers at competitive prices, passing those savings directly to our global clients. Our OEM/ODM capabilities allow us to print your logo, modify circuit diagrams for specific voltages, and provide custom packaging—all under one roof.
In an industry where a single failure can ruin a brand's reputation, we invest heavily in Automated Optical Inspection (AOI) and Burn-in Testing. Every circuit diagram we provide is a blueprint for reliability.
