The Sony Bravia XBR-Series KDL-46XBR2 46-Inch LCD HDTV features a 1,920x1,080 screen resolution that can produce high-resolution when working properly. A common set of problems can crop up, though, that either impair or can completely disable some of the Bravia's functions. With no special base of knowledge and no unique tools, however, you can troubleshoot and repair your Sony high-definition television.

Check the power connection. The Bravia has a power cord that runs out of the back of the TV. Ensure it is snugly plugged into a nearby power outlet. If it's plugged into a power strip, check the power strip's connection with the wall outlet, as well.
Check the audio/video connection if your TV has lost audio or video output. If you are using an HDMI cable for your video connection, ensure that the rectangular, black HDMI plug has one end plugged into the rectangular port on the back of the TV, and that the other end is plugged into the identical "HDMI" port on the back of your cable or satellite receiver box. If you're using a component cable instead, see the six total plugs, consisting of one red, one green and one blue, on each of the cable's ends. Survey the matching red, green and blue component ports both on the back of the television and the back of the cable or satellite box. Inspect the cable ends and make sure they are plugged into the ports of corresponding colour.
Look over the audio connection if the audio is still out. The audio connection will be established using a separate cable similar to the component cable, except this one will have just a red and a white plug on either end (for a total of four plugs). There will be matching red and white audio ports on the back of both your devices. Make the connections appropriately, ensuring you don't mix up the white and red plugs and ports.
Switch your video input choice if the connections are sound but you still aren't getting audio or video. There will be an "Input" button on the Bravia itself, as well as on the remote control. Press this "Input" button multiple times until you have cycled through all the available inputs. Eventually you will land on the one assigned to your cable/satellite box, and programming will be restored. The problem may simply be that an incorrect input is selected, such as one assigned to a DVD player.
Check around your television for other electronics in close proximity if there appears to be display errors on the TV screen. These errors can include, but are not limited to, colour bleeding and "ghosting", the latter of which occurs when images appear to double up over one another. These problems are usually caused by high-powered electronics that are too close to your Bravia, such as computers. Move these items to another location to remedy the screen issues.
