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:

    NOTE: 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.

      NOTES:
        • 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.
    5. If the TV can be operated at all, check to see if a software update is available.
      • 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 theProduct Support or Contact Sony menu.
      • NOTE: For a limited number of Internet-capable models, the only option is to turn onAutomatic 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.
  • If these options do not resolve the issue, the problem is most likely related to an internal component that must be replaced and service will be required.RF

Check whether the audio is muted by accidental press at remote control button. Enter its sound menu, and check it. If muted, as you know there will be no audio output. If not muted, check the speaker/s. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis.

Depending on the TV model, there were some where the IR (Infrared) board inside the TV failed. It is not the remote that failed. You can test the remote by trying it at a Best Buy store on some of their TV's. If you are somewhat handy, you can easily remove the IR board and send it into a repair service that I located on E-Bay. There was repair service in Indiana and one in California. I sent it to the California and it came back in less than 1 week. I installed it and the TV works fine now.

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/

Something has failed internally, either a fuse or control board or power supply board. I gather it doesn't have sound either?

I have a Sony Bravia 46'' TV. I bought a Universal WiFi Adapter from Walmart a few years ago for about $50. You have to plug it into the Ethernet port on the Bravia using an Ethernet cable (the other end of the Ethernet cable goes into the Ethernet port on the adapter). The adapter needs also a power outlet. I do not remember if the adapter came with the Ethernet cable (likely) or I had to buy it separately.

Before buying the adapter make sure that:

1. Your Bravia has an Ethernet port (on my Bravia it is in the back of the TV), and
2. You have/use a wireless router for your home network.

Hope this helps.
