The display is the soul of any Hisense TV, and the backlight is one of its important components responsible for illuminating images. If your Hisense TV brightness is unusually low or has discrepancies, the backlight might not be working. However, the backlight not working is a hardware-related issue, and you can’t consider it a cause of problems with your Hisense TV display right away. First, try some troubleshooting methods, like restarting your Hisense TV and power cycling. Then, look for any damage on the screen.
If there are no impairments and the troubleshooting also fails, go through the upcoming headings to confirm whether there is damage in the Hisense TV backlight and what you should do next.
Signs of Hisense TV Backlight Issues
You can assume that your Hisense TV backlight is not working and landed you in trouble if any of the following scenarios match yours.
- Your Hisense TV will show a black screen or a faint screen upon turning on but emit a sound if there is damage in the backlight. This will also happen if you have set the screen brightness to low. To check that, go to the Display settings if possible and increase the brightness level. If it works out, you are lucky enough.
- Your TV screen will have bright patches or dull spots here and there. Sometimes, a part of the screen will go blank. This indicates that a set of backlight strips has come out.
- Your Hisense TV screen flickers suddenly after functioning well for some time and suddenly goes off dark.
- There is a confirmed problem with your Hisense TV backlight if you notice blue tints, which usually deliver white light.
Confirming Damage in Hisense TV Backlight
If you have any of the following listed indications, put yourself into the following validations to confirm that your Hisense TV backlight has turned faulty so that you can take the appropriate actions to sort it out.
Flashlight Test:
- Turn off the lights in the room in which you have placed your Hisense TV. Then, switch on the Hisense TV.
- Take a flashlight and bring it close to its screen. Check if you can see the Home screen menu. Adjust the volume to see whether the action is reflected on the display.
- If you are able to see everything on the Hisense TV screen under the flashlight, then the backlight is the culprit for sure.
Look for the LED flashing Indication:
- Check for any flashing red light on your Hisense TV‘s LED light.
- If you detect 7 or 8 blinks on the LED, then the backlight is damaged for sure, and you can proceed with the repair with no more doubts.
- Similarly, you can judge that your Hisense TV backlight is struggling with an unstable voltage supply with 9 blinks on the LED light.
How to Fix Hisense TV Backlight Problems
After confirming that the backlight on your Hisense TV is not working, it is now time to rectify the issue. The backlight is an internal hardware component, and you have to dismantle the TV set to inspect it or perform any repair operations. So, I suggest taking your Hisense TV into an expert’s analysis in this scenario. Because they have proper training to deal with such problems.
Reach out to any TV service center near your place and show your Hisense TV to the servicemen over there. It is better to contact a Hisense-authorized center. Otherwise, it is best to contact the Hisense customer support team, who are available throughout the year to assist you. After you clearly explain what you’ve been going through, they’ll send their respective authorities to take your TV for repair. Or else, they’ll provide you with instructions on how to send your Hisense TV to their place.

In the service center, the repairmen will decode the type of backlight issue your TV is having and inform you. Either a particular bulb on the backlight strip will be burned out. Otherwise, a complete row or a set of multiple backlight strips could also be damaged. Sometimes, there would be problems in receiving the proper voltage and delivering the picture, which causes tints in different colors on your Hisense TV screen.
Be it anything, the service people over there will repair it once you accept to do it. They’ll also inform you of the compensation for the service priorly. On average, you can expect to pay $100 – $250 for backlight repair. If you have a valid warranty for your Hisense TV, you can get it done for free or at a low cost. You can even get a complete replacement with a new TV by chance if you have bought your Hisense TV recently.
After the repair, the display will return to its normal state, and you can enjoy high-quality streaming and experience different picture models by accessing the picture settings of Hisense TV.
Can I Repair the Hisense TV Backlight Myself?
This decision completely depends upon your knowledge of Hisense TV hardware. If you are already used to dismantling and repairing TVs, then you can try fixing your Hisense TV yourself.
But I would suggest not doing it. Tools for repairing are equally important to knowledge involved in this process, which most layman users won’t possess for sure. Moreover, if a damaged bulb/strip has to be replaced, you have to search and purchase it yourself, and you can’t be sure that you are purchasing the right item that matches your Hisense TV.
If something goes wrong, your Hisense TV screen will be permanently damaged. The worst part is, if you give up and contact the service center later, you can’t even apply for a warranty since your Hisense TV is not handled by a professional. So, think about all these factors before planning to repair your Hisense TV backlight.
Suppose you have the expertise and the necessary tools to repair your Hisense TV backlight, then follow the steps below to do it the right way.
- Remove your Hisense TV’s connection and keep it as it is for 30 minutes.
- Then, take the TV and place it on a clean bed with the screen coming in the bottom. Or, lay it on a table that can fully accommodate its size after keeping a spongy or thermocol sheet underneath.
- Take a screwdriver and remove the back panel screws. After that, remove the circuit board connectors and TV bezel.
- Now, remove the wires, ribbon, and the screws in the corners. You’ll get a view of your Hisense TV backlight.
- If there is any loose contact, fix it. Otherwise, carefully remove the backlight strips from the TV unit. Then, test whether all the bulbs and strips are working using a TV backlight tester or voltmeter. When you find any LED bulb is faulty, replace that with a new one.
- Suppose more bulbs are damaged, or if a particular row of backlight strips is not receiving a power supply, purchase a new backlight strip suitable for your Hisense TV model from Amazon and fix it as a replacement for the faulty one.
- Finally, assemble your TV in the correct way. Connect the power cord to a socket and turn on your Hisense TV. If your repairing work is proper, your Hisense TV will showcase a crystal clear screen without any symptoms of backlight issues you encountered previously.
Reasons & Preventions for Hisense TV Backlight Issue
| Reasons | Ways to Prevent |
|---|---|
| Inconsistent voltage supply Sudden power surges High voltage | The needed voltage for the backlight is 15 – 20 V, and the TV will take care of this distribution if it meets the overall voltage requirement. Make sure the voltage supply in your Hisense TV’s ambiance is steady and not going too high, low, or unstable. If there are problems with fluctuations in voltage supply, turn off your Hisense TV and start using it only after fixing the issue. |
| Physical damage | Don’t drop down or hurt your TV at any cost. Take extra care while relocating the TV and cleaning your Hisense TV screen. |
| Overheating | Backlight burns occur because of heat generated when you run your Hisense TV nonstop. So, rest it at regular intervals to cool down and prevent damage to the backlight. |
| Contact with water | Never let water spill on your Hisense TV, or keep it in places near water filters or sinks. Water entering the TV interior is viable for causing internal component damage or short circuits, causing the backlight not working problem. |
| Usual wear and tear | The average lifetime of Hisense TV’s backlight is 4.5 to 6.8 years. Otherwise, it can withstand an overall run time of 40,000 to 60,000 hours. If your Hisense TV backlights have gone past this limit, don’t regret replacing them. |
