Do you suddenly have your Hisense TV screen dim? Then, immediately check whether the TV has a loose connection. Most Hisense TV picture issues, especially the brightness problem, occur because of this. If you tighten the cord to the power source well, then the Hisense TV screen will brighten. If the issue is not with the connection, then you should consider other factors and troubleshoot them in a timely manner before the problem gets to a serious level.
Reasons Why You Have Brightness Problem on Hisense TV
- Low-Level Configuration of Screen Brightness Aspects
- Momentary Issues on the TV
- Functioning of Energy Saver Mode
- Usage of Duplicate Components
- Errors in Hisense TV Firmware
- Bad Signals on Input
- Internal Hardware Problems
The explanation of how these factors have kindled the Hisense TV brightness problem and solutions for them are provided in the following headings.
Low-Level Configuration of Screen Brightness Aspects
The predominant reason for your Hisense TV to have a brightness problem is the wrong configuration of certain picture aspects. You might have selected a picture mode that generally has a low brightness level, especially while planning to binge-watch overnight. Otherwise, you should have reduced the screen brightness range at nighttime, and it is now insufficient for TV viewing. If not, then the backlight level is set low.
Solutions: Change Picture Mode, Increase Brightness/Backlight Level
Change Picture Mode:
Tackle the low brightness and reach the Hisense TV Settings menu somehow. Choose Picture & navigate to the Picture Mode option. Check which picture the Hisense TV is in. If a custom preset is in the selection, change it to Standard or Cinema Day mode and see if the screen brightness increases. If not, try the following method.
Increase Brightness/Backlight Level:
On the Picture Settings of your Hisense TV, select the Display/Picture Mode Settings/Quick option based on the OS version. Choose the Hisense TV Brightness settings, and you’ll get a slider to adjust the level. Move the slider and increase the brightness of the Hisense TV screen. If you have paired the remote app with your Hisense TV, you can turn the brightness up without the remote using smartphone.
If your Hisense TV brightness problem remains the same if you have set the maximum brightness level, then the backlight level should be low for sure. So, choose this display aspect in the same section and increase its level. Now, the overall luminescence of the Hisense TV screen will upgrade and become vivid. If there is no response, then jump into the next fix.
Functioning of Energy Saver Mode
If screen brightness aspects are at an optimal level, then the Energy Saver mode is the culprit. If this function is active on your Hisense TV, then it automatically adjusts the screen brightness depending on the ambient light. Maybe the Hisense TV ambiance has good light flow currently and triggered the Energy Saver to reduce the brightness on the screen.
Solution: Disable Energy Saver
The best way to get rid of Hisense TV brightness problems due to Energy Saver is to turn it OFF. To disable Hisense TV energy saving mode, reach the option named Picture & Sound or Power & Energy on Settings. There, disable Energy Saver‘s toggle or turn its status to OFF, and it’s all done.
Your Hisense TV screen will brighten up immediately. If not, then the energy saver is not the actual reason, and you have to look for other probabilities to troubleshoot.
Momentary Issues on the TV
Occasionally, there is a chance for your Hisense TV to undergo troubles. The activity of corrupted bugs or glitches is responsible for this. The brightness problem you are currently experiencing might also be a result of this.
Solutions: Restart/Power Cycle Hisense TV
Restart Hisense TV:
A simple restart has the potential to rectify the brightness problems on your Hisense TV screen. To restart your Hisense TV, select the Restart option on the on-screen Settings. Otherwise, locate the Power button on the Hisense TV unit and hold it for about 5 seconds. You will mostly have the logo appearing bright, meaning the issue is sorted out.
Power Cycle Hisense TV:
If there is no improvement in the brightness level upon restarting, then you should try power cycling the Hisense TV. Unplug the Hisense TV cord from the power socket and leave it untouched for a few minutes. Then, make the connection again and boot up your Hisense TV, which has probably returned to a normal state.
Bad Signals on Input
This scenario might apply to users who are currently streaming with an external device connected to Hisense TV. Sometimes, a particular input source might turn problematic and start producing bad signals. Due to this, your Hisense TV screen may blink on & off, go blank, or bring a dullness to the display, like you have now.
Solution: Redo Connection, Change Input Source
Redo External Device Connection:
Turn your Hisense TV to its back and see if the connected device’s cable is fully into the input port. Insert it properly if it is not. Otherwise, remove the cable once and make sure it is not damaged. If there is insulation damage or breakage, you have to repair or replace it with a new cable. Then, connect it again to the TV input port. Turn on the TV to see if the connection is correct and if screen brightness has improved.
Change Input Source of External Device:
If the device connection is secure, then the particular input source might have turned problematic. So, unplug the connected device from the respective output and affix the cable to another input port. Then, turn on and change the input on your Hisense TV. If the specific input port was really responsible, the brightness problem on your Hisense TV will be resolved in this alternate source selection.
Usage of Duplicate Components
For almost every user who’s facing a brightness problem, this factor won’t strike the mind. Have you recently replaced the power cord or any other component with third-party products? This counterfeit product affected the normal screen capacity of Hisense TV. It can never function as efficiently as an original piece and often leads you to problems very soon.
Solution: Use Genuine Hisense Product
If you wrongly thought of saving money and replaced any of your Hisense TV components, like a cord, T-con board, or even the display panel from an unauthorized store, immediately take the TV to the Hisense service station nearby. Ask them for a parts replacement with their genuine product. Unfortunately, you can’t claim a warranty on your Hisense TV for this service.
Errors in Hisense TV Firmware
You know that outdated firmware can cause lots of issues in various aspects of Hisense TV. Maybe this could be the reason for its screen brightness issue. In the worst scenario, if you were using your Hisense TV for a prolonged time with old software, then it might be corrupted and pave the way for such problems.
Solutions: Update/Reset Hisense TV
Update Hisense TV:
First, you have to start by updating your Hisense TV to fix software issues and troubleshoot brightness problems. To do so, stand near the TV. Select the System Update or Device & Software option (varies for each OS version) and see whether a new TV software file is available. If yes, then install it by clicking on the Update Now/Install Update option.
Factory Reset Hisense TV:
If the TV firmware is already up to date, you have only one method left to try from your side, i.e., resetting your Hisense TV to factory default settings. If you have Android or Roku OS running, then find the Reset button on your Hisense TV and long-press it. Otherwise, select the Erase everything or Reset to Factory Defaults option on the Settings menu.
Now, the TV will start factory resetting and flush out everything that was problematic. Even signal issues on the port will be cleared up by now. The Hisense TV setup screen that appears now should be bright as always.
Internal Hardware Problems
If resetting hasn’t helped you out of Hisense TV problems with pictures, then the responsible factor is most likely serious. An internal component that plays an integral role in display aspects should be damaged for sure. If you have brightness problems, it should be your Hisense TV backlight or motherboard’s capacitor. Users who have old-model Hisense TVs often have their backlight dimmed or not working due to prolonged usage.
Solutions: Repair Backlight & Capacitors
If the Hisense TV backlight is not working, then it is possible for anyone to repair it themselves, having the necessary tools and replacement items in hand. However, some in-depth knowledge is required to change the capacitors since the motherboard is involved. It is better to reach out to professional servicemen in a nearby authorized showroom for backlight or capacitor replacement/repair. Or contact Hisense TV customer support and leave a service request. After the necessary service, your TV will not have problems regarding brightness anymore.
