Enhance your TV repair toolkit with the High Brightness LCD Display LED Light Bar Free Split Screen TV Backlight Tester. This innovative device is designed to simplify the testing and troubleshooting of LED backlights in LCD TVs, ensuring efficient and accurate diagnostics. Advanced Microcomputer Technology: Utilize a high-speed single-chip microcomputer for precise voltage sampling tests. This technology drives LED lights to display voltage, achieving seamless board-card integration and significantly reducing defect rates. Adaptive Voltage Testing: The tester features 0-adaptive voltage, making it suitable for testing most series and parallel lamp beads. It employs a gradual start method, allowing the voltage to automatically adapt to the current increase. This ensures that lamp beads are never burnt, reaching normal brightness within three to five seconds. Even if the positive and negative poles are connected reversely, the lamp bar and beads remain undamaged. Real-Time Digital Display: Equipped with a digital display for real-time voltage output, the tester allows for internal voltage adjustment and self-calibration. The green light-emitting tube indicates the status: "00" for short circuit and a different display for open circuit. Consistent voltage display across LED strips of the same LCD TV helps identify discrepancies and potential issues. Safe and Portable Design: The tester isolates hot and cold components, preventing electric shocks. Its integrated design combines the power cord and box, making it easy to carry and use on the go, perfect for fieldwork or home repairs. Efficient Screen Testing: Light up LCD TV screens without disassembling them. Even screens with broken lamp beads will illuminate, allowing you to identify which group of LED lamp beads is damaged by comparing voltage differences across parallel groups. This High Brightness LCD Display LED Light Bar Tester is an essential tool for anyone involved in TV repair or maintenance, offering a blend of safety, efficiency, and precision.
