IMPORTANT: In case of a third party tuner / Set-Top Box, you may only be able to switch channels with the supplied third party remote commander. The original Sony remote will not work.

NOTE: Some buttons cannot be used directly after a reboot. Wait several minutes after doing the reboot, then try.
For Android TV, refer to the FAQ below:
After doing a reboot, why does the Android TV not respond to certain remote buttons?

This article is composed of the following items. First check whether the problem is due to the TV or the remote control. If the problem is due to the remote control, you will be guided in Section by remote control type. Start checking from Section A.



Section A:
Check whether or not the TV is in operation

  1. Check that TV buttons can be operated.
    NOTE: Depending on the model, the positions of TV buttons vary.

    • If the lamp is lit or is blinking in red, proceed to Step 3.
    • If the lamp is not on, check whether or not the power cable or AC adaptor is not disconnected or loose.
      If there is no issue with the above connection, proceed to Step 3.
       
  3. Perform a power reset on the TV.
    If it caused by an external factor, such as network service/data broadcasting/connected device, it may be improved by resetting your TV.
  4. Remove external devices to confirm whether there aren't influences of external devices.
    Remove connected devices (external USB hard disk, HDMI connection device, etc.) and cables from the TV terminal.
    NOTE:
    • Do not remove the TV power cable.
    • If connections are complicated, take note of them, and make sure you can reassemble them before removing.
    • When a specific device is connected and the TV flashes, there is a possibility there is a problem with the connected device.

If you cannot operate after confirming the above, service may be required.
 


Section B:

If symptoms do not improve even after the procedures up to this step have been checked, proceed to Section C.


 


Section C:
Select remote control type (common)

Check the remote control type with the fault.
NOTE: The shape of the remote controls varies depending on the model. The following are images of typical infrared/wireless remote controls.

 Infrared Remote Control

 Wireless Remote Control

 For the Android TV remote released in 2016

    Image    

[A]: IR mark
 Image 

 Image 

[B]: Voice Search button

 If your remote has the Image (IR) mark, it is an infrared remote.
If you are using an infrared remote control, proceed to Section D.

 If your remote does not have the Image (IR) mark, it is a wireless remote.
If you are using a wireless remote control , proceed to Section E.

NOTE: If only the Image  Voice Search button does not work on the remote of the Android TV, check Voice Commands do not work on my remote.

 The Image (IR) mark is not on remote controls of Android TVs released in 2016, but they are nonetheless infrared remote controls.
If you are using these types of remote controls, proceed to Section D.

NOTE: If only the Image  Voice Search button does not work on the remote of the Android TV, check Voice Commands do not work on my remote.

 

 


 

 

Section D:
Checking items of the infrared remote control

Image  Check the following item.

NOTE: Because each of these steps represents a possible solution, check the function of the remote control after completing each step.

 

  1. Confirm the location of the Infrared (IR) remote control sensor, then note the following points.
    1. When using the remote, be sure to point it directly at the remote sensor on the device.

      NOTE: Depending on the TV model, the IR sensor is located on the left at the bottom, middle, and right of the TV screen. If there is an  Image  (IR) mark, the IR sensor is located next to the mark. For details, refer to the manual supplied with the product. Image
    2. Remove any obstacles that may be in the path between the remote and the device.
      • Make sure that the remote infrared receiver / sensor located on the product, has not been covered or obscured by indoor plants or furnishings etcetera.
      • When using a sound bar, make sure that it does not block the IR sensor of the TV.
      • Glass enclosures, as well as fluorescent or halogen lights, may prevent the IR signal from reaching the TV.
      • Low energy light bulbs have been known to interfere with remote frequencies. Try moving the products away from the lamp or the lamp away from the products.
    3. Make sure that a bright light or bright sunlight does not shine on the IR sensor.
      Bright light and bright sun light can sometimes interfere with infrared signals, especially if the light is direct upon the IR sensor of the TV.
  2. Verify that the remote is sending an IR signal .
    By looking at the transmission unit of the infrared remote control through the camera of a mobile phone or digital camera, you can check whether or not the remote control is sending a signal. This way you can verify if your batteries are dead or the remote control has been damaged. Bear in mind that it is possible that, if your remote control has been damaged by liquids or shocks, the infrared signal might still be visible, but is sending faulty data.
  3. Update the TV software to the latest version .
    There is a chance that symptoms may improve by updating to the latest software.
    NOTE:
    • Operate using the buttons on the TV or another remote.
    • Download and update processes will take time.

The troubleshooting steps above should resolve the issue. If you completed all the steps and the issue is not resolved, service may be required or the remote may need replaced.

 


Section E:
Checking items of the wireless remote control

IMPORTANT: If the issue occurs on the Touchpad Remote Control of the Android TV, check  Troubleshooting for Touchpad Remote Control .

 

 Image  Check the following item.

NOTE: Because each of these steps represents a possible solution, check the function of the remote control after completing each step.

[A]: Touchpad Remote
[B]: One-touch Remote

 

  1. Register/re-register the wireless remote.
    You can use the wireless remote only after registering to the BRAVIA TV. Register/re-register the wireless remote using the operation buttons on the BRAVIA TV or infrared remote. Even if you have already registered it, the issue may be improved by re-registering.
    For how to register, refer to the following.
  2. If the radio device is installed near the TV or remote, confirm whether there is no influence of the radio device by changing the installation location, etc. Radio emitted from the wireless remote may be affected by radio devices such as a wireless access point (wireless router), radio cordless handset, mobile device, microwave, cordless phone, etc.

  3. When an old splitter is attached near the back of the TV, verify whether the issue is improved by temporarily removing it. There is a possibility that the radio wave which leaks from the old model splitter intervenes with the radio wave of the wireless remote. If you remove the splitter to improve the issue, verify if the issue is improved after you replace the old splitter with the new one.
