SOURCE: my sony bravia has no audio when used as cable tv

Check the connections between the cable box and the TV. If you are using scart check the connector is in squarely if using rgb or composite you need a separate audio connection using the red and white phon sockets.

SOURCE: How do I replace the IR remote sensor on my LG TV?

My LG TV stopped responding to the remote. A very helpful repair technician told me to stick a head phone jack in the sensor jack on the back of the TV a few times to clean out the contacts. Now the remote control works fine.

Hi,
Remote sensor seems bad in your KDL-40D3000 that will be replaced because it is unable to receive remote infra red signals and remote has been tested on other tv and found good.

SOURCE: Philips 47PFL3603D LCD TV -

Hi,
There could be many reasons like IR pins not soldered properly, it is not getting +B supply or IR output signal is blocked, buffer transistor on same board is bad etc etc
Replacement IR Board is available for $6 at Encompass.com so I would suggest to replace complete board instead of IR Sensor.
Hope these info will help you.
Thanks.

I got a brand new sensor put in my sony bravia kdl 32l500 and my remote model y0922021765 still wont work how do I reprogram it


Hi Stacy,
If you have replaced the sensor correctly and it is not working means either the remote control is not working or the TV is not responding. Please press any key on the remote control and see it through your mobile phone's camera. If the remote control is working you will see the IR led flashing. Secondly, if the TV is not responding please check the voltage on the legs of the sensor, if you are handy with a multi meter and let me know.

RM-GA014 remote can't switch Sony Bravia 46" tv on


Follow this procedure to troubleshoot if the TV does not respond to the supplied remote control.
  1. Remove the batteries from the remote control.
  2. Press each button on the remote control twice.
  3. Make sure none of the remote control buttons are jammed.
  4. Install fresh batteries into the remote control. IMPORTANT: Make sure the batteries are inserted in the (+ and -) direction shown inside the battery compartment.
  5. Make sure nothing is blocking the Infrared (IR) sensor on the TV. IMPORTANT: Some locations can interfere with the IR signal from the remote control. Glass enclosures, as well as fluorescent or halogen lights, may prevent the IR signal from reaching the TV.
  6. Point the remote control at the IR sensor of the TV.
  7. Press the POWER button and other buttons to test TV operation. IMPORTANT: Do not hold down the POWER button too long. Doing so may prevent the remote control from operating the TV.
    NOTES:
    • If some of the remote control buttons operate the TV but others do not, the remote control may need replaced.
    • If all of the remote control buttons work, no further troubleshooting is required. Otherwise, continue troubleshooting below.
  8. Try using the remote control at varying distances from the TV. IMPORTANT: Using the remote control too close or too far away may prevent the IR signal from reaching the TV.
  9. Turn the Light Sensor setting to OFF.
    1. On the TV itself, press the HOME button on the TV.
    2. Using the up arrow or down arrow select Preferences.
    3. Press the INPUT button.
    4. Press the up arrow or down arrow to select ECO.
    5. Press the INPUT button.
    6. Use the up arrow or down arrow to select Light Sensor.
    7. Press the INPUT button.
    8. Press the up arrow or down arrow to select OFF.
    9. Press the INPUT button.
  10. Power reset the TV.
  11. Make sure the TV has the latest system software (firmware) update installed, if applicable.
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 control may need replaced. Contact the Customer Experience Center at (239) 768-7547 to speak with a service representative for further assistance.

Sony bravia kdl 32l 5000 does no respond to remote controls


Check the remote control for its infrared emission. Check it with fresh batteries. If remote control is found OK, check and replace the infrared sensor inside the TV. If you wish to get some details, check the site linked here. Pull up older posts. Check the site in 'Mosaic' view. It will make search easy. http://electronicshelponline.blogspot.com/

On the original SONY remote press display to remove that---if left on long enough it will actually burn that image into the screen--button on almost any Sony Tv remote will remove or clear it.

Hi.

If you have no picture, no sound and the TV stays in standby it is not the remote sensor. That is the TV in protect mode (forced standby). The TV goes in forced standby when an internal problem is detected. Most Sony have buttons on the TV set. If problem is the IR sensor the TV Twill wake up if you press the channel buttons on the set. Try disconnecting power cord for ten minutes. If that does not work call the Sony support number listed in your user guide.

Regards.
