55 in Sony TV turns off and on by itself

My 55 in Sony TV turns off and on by itself. I turn the TV on and a few minutes later it will turn itself off. A green light begins flashing (it flashes about 30 times) and then the TV turns back on.

Re: 55 in Sony TV turns off and on by itself

The same problem is occuring with my Sony LED EX330. And I have applied all the solution provided. But the problem still exists. Even people from Sony Service center took my TV with them for rectification and delivered by saying, we have changed the Mother Board and  your TV is all right now. This happened twice but the problem is still exist. I dont know how trained your engineers are, but I want my TV either to be replaced or the problem should be fix. Otherwise, I have to go to consumer court and I will update these problem and your inability to fix it on FACEBOOK and TWITTER.


Please look in to this matter as soon as possible.


Thanks in advance,

Vishwajeet Singh

Re: 55 in Sony TV turns off and on by itself

I have the KDL-70R550A model and the TV was turning itself on and off my itself, no lights blinking.

I tracked the problem down to this firmware update,. To fix do a hard reset the TV without connecting to the Internet. It will reload the factory firmware. Set the TV not to automatically load updates in settings,

Re: 55 in Sony TV turns off and on by itself

Hello RomanLama




Welcome to the Sony Community!  



Please perform power reset. Here are the steps: 

  1. Turn off the television.

    IMPORTANT: For a projection television that uses an internal lamp, wait 5 minutes after turning off the television to allow the lamp to cool before continuing with the following steps.

  2. Unplug the television power cord from the electrical outlet.
  3. Let the television remain without power for 60 seconds.
  4. Plug the power cord back into the electrical outlet.

    NOTE: If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.

  5. Turn on the television.


NOTE: Please make sure to remove all the connected devices before you reset the TV. 


For further assistance regarding your concern, please contact the Sony offices/Sony representative offices nearest to your place of residence in Asia Pacific region Due to proximity, they are in a better position to respond to your questions or concerns.

[ Edited ]

Hi All,


For further assistance about the Red, Green or Orange lights that are ON or BLINKING on the TV.


Check below for the common meanings of the indicator lights and troubleshooting steps to help resolve any issues.


LED Indicator lights are normally found on the lower front of the TV. There may be one or more lights and on newer sets, one light may change color to indicate different conditions or to show that certain features are enabled.




System Error:
If a Red LED is blinking and the TV is not working properly it means that the TV has detected an issue or problem. Most Red LED blink conditions require service. The meaning of the blink codes differs between TV models, but the following steps may resolve user serviceable errors related to heat, temporary conditions, or software updates:


8 Times Blink - For certain models, a special reset procedure is needed if the Red LED on the front of the TV is blinking 8 times and then repeats. This is a model-specific issue that may be resolved by following these steps (please check the answer to be sure your model is included).

For other TV models or other Red LED blink codes:

1) Turn the TV off and back on. If the TV will not respond to the remote or the power button, or if that does not fix the issue, unplug the TV. For a Projection TV or Projector , leave it off for 3 minutes. For other TVs leave it off for 1 minute. Plug the TV it back in and turn it on.


  -If the TV is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.

  -Projection TVs and projectors need to cool down before they will turn on again. You may need to wait several minutes before these will turn back on.


2) Clean any vents/slots in the TV cabinet and make sure there is room for air to circulate around the cabinet of the TV.


3) Some Sony TVs have a media box (tuner) and separate display. If you have one of these TVs, check to make sure the cable between the media box and the display is securely connected.


4) For Projection TVs and Projectors, make sure that the cover/door for the lamp is closed and secure.
If the TV can be operated at all, check to see if a software update is available.


5)If your TV is connected to the Internet, press the Home or Menu button on the remote to get into the setting menus. The Software Update option is usually found under the Product Support or Contact Sony menu.


- For a limited number of Internet-capable models, the only option is to turn on Automatic Software Updates and allow the TV to update on its own. If you only have this option, make sure it is set to On. Automatic updates are only downloaded when the TV is in standby mode (turned off with the remote but not unplugged). Normally this download will happen overnight but may take up to 24 hours.


- Software and driver updates for your Sony product are available online. You can check to see if a software (firmware) update is available for your television. Steps to install will be included if an update is available.


- Older CRT TV's and TV's that cannot be connected to the Internet do not have an option to check for a software update or may not capable of being updated.




- A solid Orange/Amber light means that a timer has been set and is active on the television


  - Sleep Timer - the TV will turn off after a set amount of time
  - On/Off Timer - turns the TV on and off at set times of the day

     NOTE: Timers can be set, changed, or turned on/off in the
                  Settings menu of the television.


Software Update:
- For an Orange/Amber blinking light with LCD and Plasma displays that have a have a media box (tuner) and separate display., check to make sure the cable between the media box and the display securely connected.


- For other TVs, a blinking Orange/Amber light means that the television is receiving a software update. This only happens if your TV is connected to an active high-speed Internet connection.

  - Do not turn off the television or remove power during a software update.
  - Your remote control will not work while an update is being downloaded/installed.
  - Updates may take a few minutes to download and install. Please be patient. The TV will return to normal              operation after the update finishes.




Blinking while TV is turning on:


- A Green or White light may blink while the TV is powering on. This is normal and will stop once the TV comes on. If the light continues to blink and the TV does not come on or if the TV comes on and then turns off and the process starts over again, unplug the TV for 3 minutes then plug it back in and try again. If the problem continues, the TV will need to be serviced.


- If a Green or White light blinks followed by a Red blinking light, follow the steps above for the Red blinking light.




Solid or blinking while the TV is on:


- A solid Green or White light on the front of the television means that the TV power is on.


- A Green or White light that blinks when you press a button on the remote control simply shows that the TV is receiving the signal from the remote. Not all televisions have this feature.
NOTE: Some newer TVs have a white LED in lower center under the screen. If desired, this LED can be turned off in system settings.




Replace Lamp (For Projection TV or Projector only):


- If the Lamp Light is blinking it means that the lamp has burned out and needs to be replaced.

- When replacing the lamp be sure not to touch the glass surface. If you accidentally touch the surface of the          lamp, clean it with an alcohol wipe to remove any oil residue. If you do not do this, the life of the lamp can be      shortened.

- Make sure to properly close and secure the covers/doors for the lamp.

- Part numbers for replacement lamps can be found in the Replacement Lamp Part Number table.





- TV is turned off or the TV is not plugged in.

- On some sets, this may indicate that the Energy Saving Switch on the side of the TV is turned Off. If your TV

    has this switch, it must be turned On for the TV to operate.
