Máy kiểm tra đèn nền TV LCD độ sáng cao 0-320V GJ2C

GJ2C LED TV backlight tester is a light source power supply that consist of isolating switch power supply, constant current circuit, current control circuit and LED digital voltage display system. With help of GJ2C, you can know where the problem of LED lights is quickly. Excellent tool for diagnosing and finding out defective LEDs in backlights. Features:High brightnessCan test LED beads, LED panel, Zener diode, etc.It is suitable for LED TV/lamp/computer repair and all LED application.It can automatically regulate current and voltage without doing harm to devices.No need to disassemble LED TV backlight and other LED applications when you diagnose the defective LEDs.It can also be used to measure the voltage of different applications, capacitor voltage. Instructions:1) Plug the power supply, voltage shows 160V and after few seconds it would rise up to 320V.2) When testing, use the red and black pen to touch anode and cathode of the LED light respectively. The light will automatically change from slight brightness to high lightness gradually (3-5s) and then stabilized. The voltage display is the operating voltage of the light at that time. Method without disassembling the screen:1) Unplug the interface sockets of the constant current plate and light bar;2) Insert the red and black pens into anode and cathode of the interface of the LED light bar.3) Turn on the power supply and power the TV up normally (except for the constant current plate); at this time, if the light bar, LCD, mainboard and logic board all work normally, normal images can be seen from the screen. The brightness may be lower than the normal brightness of the original TV set. The output current of the tester shall adapt to the LED backlight bars of all sizes of TV sets, thus the brightness is relatively lower compared to the one-to-one constant current plate of the original TV set, which is a normal phenomenon.
