Your Sony TV has a blue tint due to an incorrect color setting or because your backlights are having issues and need to be replaced.
The blue tint issue is common with LED TVs since they’re more likely to develop backlight issues with time. Luckily, this issue can be fixed by following some troubleshooting steps.
In this article, we will provide answers to why your Sony TV screen has a blue tint and solutions to fix this issue.
Why is My Sony TV Screen Blue Tint?
If your Sony TV screen has a blue tint, it does not generally mean that your TV is damaged. It might just be an issue with an incorrect picture preference since Sony TVs have inbuilt features that allow you to adjust your color settings.
The blue tint on your TV is not only caused by an incorrect color setting. Here are some issues that can make your Sony TV have a blue tint effect:
1. Incorrect Color Settings
In most cases, the blue tint issue might have been caused by a wrong color setting. There are many color settings options available in your TV settings and they will change the way pictures are displayed on the screen if they’re not set up properly.
On a Sony TV, you can set up your Color Temperature, Color Tone, White Balance, Brightness and Contrast, and so on.
2. Problem with HDMI Cable
Another reason why your Sony TV has a blue tint is due to the HDMI cable being loose or damaged.
3. Outdated Firmware
Most gadgets are known to have periodic firmware updates to fix certain bugs and improve performance. One way to prevent the blue screen issue on your TV is to keep its firmware up-to-date.
4. Problem with Backlight
The backlights on your LED screen are responsible for how pixels appear on your screen. It is common for your TV screen to have a blue tint if the backlights are faulty.
How to Fix Sony TV Screen Blue Tint Issues
We’ve provided answers to why your Sony TV has a blue tint above. Now, let’s look at troubleshooting steps to fix this issue.
To fix the blue tint issue on Sony TV, change your picture settings, check your HDMI cables for fault, keep the firmware up-to-date, and change your backlights.
1. Change Picture Settings
Modern televisions have built-in features that allow you to customize your picture preferences, such as the tint effect. If your Sony TV screen has a blue tint, then this option might be enabled in the settings.
Here’s how to change the picture settings on your Sony TV.
- First, press the Home button on your Sony TV remote control.
- Next, go to Settings, then select Display from the menu.
- Select Picture.
- Now, select Picture Adjustments and change your preferences.
Here’s a breakdown of the options and their functions.
Picture Mode
This option allows you to change the picture modes between Vivid, Standard, Custom, Cinema Pro, Cinema Home, Sports, and Animation. There is a list of other modes, depending on your preferences.
Brightness
Using this option, you can adjust the backlight. Since this option has to do with increasing lighting on your screen, it can lead to increased power consumption when the screen is brighter.
Color Settings
This option allows you to make changes to the color saturation level and hue. Adjust your color settings until the blue tint is no longer visible.
You can always reset your picture settings to default by clicking on the Reset option to reset the changes made to your picture settings to their factory default.
Note: The options available on the picture settings might have different names or locations depending on your TV model, but the functions are the same.
2. Check HDMI Cable
If you’re still having a blue tint on your Sony TV even after updating your picture settings, then the problem could be due to a loose or damaged HDMI cable.
To diagnose this issue, try switching to other inputs to see if they also have a blue tint. If the blue tint only appears on the HDMI input, then there is something wrong with the cable. If that’s the case, here are steps to follow:
- Check the HDMI port on the TV and make sure the cable is not loose.
- Examine the cable for damages.
- Consider replacing the cable, since it might have been damaged.
- If the HDMI cable is connected to a DVI converter, ensure that the connection doesn’t come loose.
- Use a different HDMI port on the TV since there is a possibility your current port is damaged.
3. Perform a Power Cycle
Performing a power cycle will fix your Sony TV if it has a blue tint since the process will reset your mainboard. Follow the steps below to perform a power cycle on your Sony TV.
- Power off your Sony TV and unplug it from the power outlet.
- Next, wait for about 60 seconds and then it back into power.
This process is known as a soft reset. Do not worry, all your settings will still be intact.
If your TV still has the blue tint issue after following this step, go to the next solution.
4. Update TV Firmware
Your TV will have issues if its firmware is not up-to-date. This is because the firmware is the software that controls your TV functions.
Let’s look at how to update the firmware on your Sony TV:
On Android TV with Google TV models
- First, press the Quick Settings button on your remote control.
- Next, select Settings, and then System.
- Select About, then System Software Update.
- Finally, select Software Update and follow the onscreen instructions.
On Android TV models
- First, press the Help button on your remote control.
- Next, select Status & Diagnostics, and then System Software Update.
- Finally, select Software Update and follow the onscreen instructions.
Make sure your TV is connected to the internet before checking for updates. If your TV doesn’t have Internet access, you can still update its firmware manually using a USB flash drive.
In that case, you’ll need to manually download the update from the Sony Support website and then install it using a flash drive. Before going ahead with this option, here are some things to note:
The flash drive must be formatted in the FAT16, FAT32, exFAT, or NTFS format.
It must have sufficient free space to accommodate the updated file, and the file must be saved in the root directory.
Follow the steps below to update Sony TV firmware manually:
Note: Make sure you have stable power and don’t press any buttons during the update. Loss of power during the update can cause hardware damage.
- First, go to the Support website.
- Next, type in your TV model name in the search box.
- Once you find your model, go to the Downloads section and click on the firmware update version.
- Finally, follow the instructions on the website to download the update to a USB flash drive and complete the process.
5. Replace your Backlight
If you’ve followed the steps up to this point and your Sony TV still has a blue tint, then you might consider replacing the backlights.
Backlights are simply light sources that are found inside a display to provide lighting for the screen. Backlights can degrade over time with long use at a high brightness level.
We’ll provide a video guide to assist you with the process of replacing your TV’s backlights. If you’re not a TV repair professional, it is not recommended to try these steps.
Before we get started, make sure you have tools like a screwdriver set to help us take apart the TV and the new backlights.
Also, confirm that your Sony TV has replaceable backlights. Some models have backlights that are built into the screen and cannot be replaced. Where to confirm? Check your owner’s manual or contact Sony support.
Follow the steps below to replace your Sony TV backlights:
- First, turn off the Sony TV and unplug it from power.
- Use a screwdriver to remove the bezel screws on the TV’s back.
- After taking off the back, disconnect the backlight cables.
- Unscrew the the backlights, and carefully take them out.
- Place the new backlights in the same spots as the old ones and screw them.
- Reconnect the backlight cables, and screw the TV back in place.
Your TV should now work fine, and the blue tint issue should be fixed.
