Description

SFD‑290 High Brightness LED Backlight Bead Tester - Your Essential TV Repair Tool Advanced Microcomputer Technology: The SFD‑290 is equipped with a high-speed single-chip microcomputer that performs precise voltage sampling tests. This innovative design integrates the LED light display voltage directly onto the board, unlike other products that require separate installations. This integration reduces the defect rate by maintaining a constant current and providing a reliable voltage display function. Self-Adaptive Voltage Range: With a 0-300V self-adaptive voltage capability, this tester is perfect for testing most series and parallel lamp beads. The progressive start mode ensures that the voltage is automatically adjusted while the current gradually increases, preventing any damage to the lamp beads. Within three to five seconds, the lamp beads reach their normal brightness, and the device safeguards against damage even if the anode and cathode are connected in reverse. Real-Time Digital Display: The tester features a digital display that shows real-time voltage output with adjustable settings. The green LED tube provides clear readings, displaying "00" for short circuits and "300V" for open circuits. This feature allows you to ensure that each group of LED strips on the same LCD TV displays the same voltage, facilitating accurate diagnostics. Safe and Portable Design: Designed with cold and heat isolation, the SFD‑290 ensures no risk of electric shock. The power cord and case are integrated into a single unit, making it easy to carry and use in various settings. Efficient Screen Testing: Illuminate the LCD TV screen without the need to disassemble it. Even screens with faulty lamp beads can be lit up, allowing you to identify which group of LED lamp beads is damaged by observing voltage differences across parallel groups. Eye Safety Precaution: Due to the high brightness of the lamp beads during testing, it is advised not to look directly at them to avoid eye strain or injury. Choose the SFD‑290 High Brightness LED Backlight Bead Tester for a reliable, efficient, and safe solution to all your TV repair needs.
