The Phewnyzo Super LED Tester is designed for TV backlight repair, inspection and testing of LED lamp beads and strips. It accepts an 85-265V input and provides a 0-300V adaptive voltage range for testing most series and parallel LED bead configurations. This range supports a variety of LED backlight arrangements while the gradual starting mode helps prevent lamp bead burn out during the test process.A high-speed single-chip microcomputer handles voltage sampling and LED lamp display functions. The tester also includes an adjustable circuit with a real-time digital voltage output display, allowing the voltage to be adjusted for precise measurements. These controls provide a direct way to monitor the displayed output while checking LED lamp beads and identifying irregular components in a backlight assembly.The unit is intended to help identify and isolate faulty LED lamp beads without removing the LCD screen. This can support inspection of TV backlight sections while the screen remains in place, based on the included testing design. Hot and cold isolation provides safety during operation, and the integrated power cord keeps the cord connected to the box-style tester for transport and setup. The box design is described as portable for moving the tester between work areas.The tester uses a US plug and has product dimensions of 6.69 x 4.06 x 2.28 inches with a product weight of 8.8 ounces. The package dimensions are 6.7 x 4.1 x 2.3 inches and the package weight is 0.55 pounds.
