The backlight is a crucial part of LCD and LED TVs, responsible for providing the light that allows images to be displayed on the screen. However, like any hardware component, the backlight on your Hisense TV may occasionally stop working or malfunction. This can happen for various reasons, such as power surges or faults within the internal components.
When the backlight encounters issues, it can result in problems like a black screen, white spots, flickering, or a blue tint on your Hisense TV. In this article, we’ll guide you through some fixes that you can try on your own to address and fix backlight problems on your Hisense TV.

If the backlight on your Hisense Smart TV is malfunctioning, you might notice the following signs:
- The TV turns on, but no picture is displayed on the screen.
- The Hisense screen appears unusually dim, even after adjusting the brightness settings.
- One half of the screen is dark, while the other half functions normally.
- Certain areas of the screen are darker than others.
- The Hisense TV screen flickers and may work fine for a while before suddenly turning off or blinking.

These symptoms can help you identify if the backlight on your Hisense TV is damaged.
Primary Solutions to Fix Backlight Not Working on Hisense Smart TV
In this section, we outline multiple troubleshooting steps that can help you resolve issues with the backlight not working on your Hisense Smart TV.
Fix Voltage Issues
- A sudden spike in voltage damages the circuits connected to your TV’s electrical components, including the backlight. These power surges can lead to the burnout of LED bulbs and may even cause short circuits.
- Heavy-duty power tools are a common source of power surges. To protect your Hisense TV from voltage-related damage, it’s advisable to use a high-quality surge protector. This device can help shield your TV from excessive voltage and prevent power surge issues.
Power Cycle Your Hisense TV
Eliminate unwanted bugs and enhance its overall performance by performing a power cycle on your Hisense TV. Follow these steps to restart your Hisense TV:
- Turn off your Hisense TV and unplug the power cable from the socket.
- Press and hold the Power button on the Hisense TV for a few seconds.
- Let the TV sit idle for 15 minutes.
- Afterward, reconnect the power cable and turn the TV back on.
Check if the backlight issue has been resolved on your Hisense Smart TV.
Cool Down Hisense TV
- To prevent your Hisense TV from overheating, avoid placing it in direct sunlight or near bright light sources, as this can cause the backlight to overheat and malfunction.
- Ensuring proper ventilation and maintaining a suitable temperature can easily resolve this issue. It’s advisable to keep your TV in a well-ventilated area to help it cool down.
- Additionally, using a vacuum cleaner to clear any dust that may have accumulated in the vents can improve airflow, helping to cool the internal components. After allowing your TV to cool down, turn it back on to see if the backlight is functioning correctly.
Replace Backlight LED Bulbs
The LED bulbs in the backlight strip have a limited lifespan and can burn out due to excessive heat. Since these bulbs are connected in series, a single damaged LED can impact the entire backlight.
If this happens, you’ll need to replace the LED bulbs by removing the back panel and accessing the circuits of your Hisense TV. It’s recommended to carry out this replacement with the assistance of a technician or by following a detailed repair guide.
Inspect for Physical Damages
- Examine your TV for any physical damage that might have caused the LED strips to shift out of place, leading to backlight issues. Additionally, if your TV has come into contact with water, it could result in backlight failure.
- To address this, start by unplugging your TV and cleaning it thoroughly with a non-abrasive cloth. Ensure the TV is completely dry. Or use a blow dryer to dry any affected areas.
Hardware Issues
- If your Hisense TV’s backlight is still malfunctioning, the issue could be with the T-CON board, a critical component responsible for creating images on the screen.
- If the T-CON board is the culprit, you can either call a technician or carefully replace it yourself by opening the TV’s back panel. Additionally, it’s important to check for other potential hardware issues within your TV.
