Troubleshooting
If the TV seems to have a problem, first review this list of possible problems and solutions. Alternatively, review
the Troubleshooting Section in the e-Manual. If none of these troubleshooting tips apply, please visit “www.
samsung.com” and click on Support, or contact the call centre listed on the back cover of this manual.
This TFT LED panel is made up of sub pixels which require sophisticated technology to produce. There may
be, however, a few bright or dark pixels on the screen. These pixels will have no impact on the performance
of the product.
To keep your TV in optimum condition, upgrade to the latest software. Use the Update Now or Auto update
functions on the TV's menu (
> Settings > Support > Software Update > Update Now or Auto update).
The TV won’t turn on.
Make sure that the AC power cord is securely plugged in to the TV and the wall outlet.
Make sure that the wall outlet is working and the power indicator at the bottom of the TV is lit and glowing
a solid red.
Try pressing the Power button on the TV to make sure that the problem is not with the remote control. If
the TV turns on, refer to “Remote control does not work” below.
There is no picture/video/sound, or a distorted picture/video/sound from an external
device, orWeak or No Signal” is displayed on the TV, or you cannot find a channel.
Make sure the connection to the device is correct and that all cables are fully inserted.
Remove and reconnect all cables connected to the TV and the external devices. Try new cables if possible.
Confirm that the correct input source has been selected (
> Source).
Perform a TV self diagnosis to determine if the problem is caused by the TV or the device (
> Settings >
Support > Self Diagnosis > Start Picture Test or Start Sound Test).
If the test results are normal, reboot the connected devices by unplugging each device's power cord and
then plugging it in again. If the issue persists, refer to the connection guide in the user manual of the
connected device.
If you are not using a cable box or satellite box, and your TV is receiving TV signals from an antenna or
a cable wall connector, run Auto Tuning to search for channels (
> Settings > Broadcasting > (Auto
Tuning Settings) > Auto Tuning).
The Auto Tuning Settings may not appear depending on the model or geographical area.
If you are using a cable box or satellite box, please refer to the cable box or satellite box manual.
