The backlight issue is one of the rare Hisense TV problems that may occur when there are any serious issues with your TV’s back panel. A backlight is one of the important components of a TV, and it illuminates the LCD panel, allowing you to see the picture clearly on the TV screen and providing better color and contrast. Essentially, the primary reasons behind the backlight not working in a Hisense TV are,
- Faulty LED lights within the backlight panel
- Damaged TV screen
- Malfunctioning circuit board
- Short circuits
- Faulty power surges
- Inductor failure
- Damaged T-CON board
Understand the Fixes for Hisense TV Backlight Not Working
If your Hisense Smart TV undergoes any of the listed fixes, you can follow the below solutions and fix the backlight that is not working on your TV.
Power Cycle Hisense TV
A simple power cycle can resolve the temporary glitches and issues that are affecting your Hisense TV’s backlight. As an initial step, make sure to restart your Hisense TV and check if the Hisense TV is working properly without any issues.
- First, detach the power cable from your Hisense TV and the power socket.
- Then, look for the Power button on Hisense TV and press it.
- Hold the button pressing for about 15-30 seconds to drain out the excess power.
- Once done, plug back the power cable into the necessary sockets and turn on the switch.
- Now, check whether the backlight issue is fixed and your smart TV screen is working properly.
Check for a Blown Fuse on Hisense TV
It is also important to check the fuse of your desired Hisense TV. This is because a blown fuse in a TV can cause the backlight not to work, resulting in a dark screen with a sound. As the fuse is designed to protect the TV circuit from excessive current, a blown fuse will not send power to the backlight, resulting in an issue. So, make sure to check and replace the blown fuse on your Hisense TV. Additionally, you can take precautions to prevent your Hisense TV fuse from blowing.
Inspect the Power and Mainboard of the TV
The power board and mainboard are often the problems that cause the backlight not to work effectively. Moreover, you must inspect the capacitors and other internal components of the TV to ensure proper usage. Suppose you need to replace it, then it’s much easier to replace the entire power board rather than replacing any individual components.
If you are an expert user who is well-versed in handling the electrical components, you can proceed to dismantle and replace the Hisense TV power and mainboard. Otherwise, contact Hisense customer service and get their help to replace the damaged component.
Check the LED Strips
Sometimes, the backlight in a TV may not work if the LED strips are burned out. Modern Hisense Smart TVs come with LED strips of various lengths and may fail due to current overpowering. Also, changing the LED strips is a hectic process that needs to remove the back panel and remove all the circuit boards and connectors. In this case, then purchase a new LED strip from Amazon and replace them using expert technicians.
Test the Hisense TV Backlight
You can also confirm whether the issue is with the Hisense TV’s backlight or any other component by performing a flash test on the TV screen. To perform this, make your TV room dark by switching off all the lights in it.
Then, fetch a torchlight and flash the light in front of your TV screen. Move the light on the TV screen and check whether you can see any moving images. If you find any dull images, then you can confirm that the fault is with the TV’s backlight itself.
If this is the case, visit a nearby television center and replace the Hisense TV backlight with the help of a technician. The backlight of a Hisense Smart TV varies from $10 to $20, and the repair process may cost from $59 to $199.
Contact the Hisense Support Team
One of the last troubleshooting steps to recover your Hisense TV’s backlight is to contact the Hisense professionals. Diagnosing and repairing the internal components is a risky task. In most cases, replacing the faulty backlight components requires specialized tools and knowledge. So, it is advised to seek help from the repair technicians for a smooth replacement process.
