•• 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).

•• 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, or “Weak 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.
