*LED LCD screen TV backlight problems are getting increasingly common. As we know, slight voltage change can have a big influence on TV function. *Excellent tool for diagnosing and locating bad LEDs in backlights. *With help of this tool, you can know the LED LCD screen backlight problem quickly. *Testing the backlight of LED at any size display the voltage, It can be tested in a long time, and will not damage the lamp beads.
MAIN APPLICATION
1.Testing the LED TV backlight without disassemble.Applicable to any size LED TV backlight repairs. Testing of LED stirng, LED panel,COB and integrated LED lights,etc.(DO NOT LOOK DIRECTLY AT THE LIGHT.) Testing of single LED bead.(Don¡¯t connect the probes to the LED for a long time if you can¡¯t determine the ¡°+¡±and ¡°-¡±.) 2.Test voltage parameters for DC power(<300V). 3.According to the voltage to determine open-circuit,short circuit and the number of the light beads in series. 4.Check for electric leakage.
Test Method without Disassembling the Screen
a. Unplug the interface sockets of the constant current plate and light bar. b. Insert the Red and Black pens into the anode and cathode of the interface of the LED light bar. c. Turn on the TV power supply and power the TV up normally (except for the constant current plate); at this time, if the light bar, LCD, main board and logic board all work normally, the screen display normally. The brightness may be lower than the normal brightness of the original TV set. d. The voltage of each group of light bar should be the same, otherwise, there must be problems with the light bars.
ATTENTIONS
1. Please disconnect the power of the detected object first.(If you use to test TV backlight,you should make sure the LCD screen is powered on.) 2. Plug in power,it can be used after 5 to 10 seconds to reach 320V.The soft start mode make the backlight getting brighter slowly. 3. Don¡¯t connect the probes to the LED for a long time if you can¡¯t determine the ¡°+¡±and ¡°-¡±. 4. Don¡¯t touch the output terminal of probes for a long time .It¡¯s safe for touch the probes in short time periods. Matters need attention: You can judge the TV backlight is well or not without disassembling the screen.It has no size limited.
