In some cases, a faulty internal component may be causing the backlight to malfunction, requiring professional diagnosis and repair.
By carefully checking the power supply and connections, you can eliminate common external factors that could be causing the backlight issue with your Hisense TV and narrow down the potential causes for further troubleshooting.
Testing The Backlight Leds
To test the backlight LEDs on your Hisense TV, you will need to use a multimeter. Start by unplugging the TV and removing the back cover to access the LED strips. With the multimeter set to measure voltage, carefully place the black probe on the metal frame of the TV and the red probe on the positive side of the LED strip connector. If the multimeter shows a reading, the LEDs are receiving power and may not be the issue. However, if there is no reading, it indicates a problem with the backlight LEDs.
Next, you can test the individual LEDs by using the diode test function on the multimeter. Place the probes on the positive and negative terminals of each LED. A working LED will show a voltage drop and a lit-up display on the multimeter, while a faulty LED will not produce any display. Carefully examine the entire LED strip and identify any dim or non-working LEDs as these will need to be replaced. If the LED strip appears to be functioning properly, then the issue may lie elsewhere in the TV’s circuitry.
