Picture Test

If you think you have a picture problem, perform the picture test. Check the colour pattern on the screen to see if the problem still exists.

•Yes : If the test pattern does not appear or there is noise in the test pattern, select Yes. There may be a problem with the TV. Contact Samsung‘s call centre for assistance.

•No : If the test pattern is properly displayed, select No. There may be a problem with your external equipment. Please check your connections. If the problem still persists, refer to the external device‘s user manual.

Sound Test

If you think you have a sound problem, please perform the sound test. You can check the sound by playing a built-in melody sound through the TV.

•Yes: If during the sound test you can hear sound only from one speaker or not at all, select Yes. There may be a problem with the TV. Contact Samsung‘s call centre for assistance.

•No: If you can hear sound from the speakers, select No. There may be a problem with your external equipment. Please check your connections. If the problem still persists, refer to the external device‘s user manuall.

Note

If you hear no sound from the TV‘s speakers, before performing the sound test, make sure Speaker Select is set to TV speaker in the Sound menu.

The melody will be heard during the test even if Speaker Select is set to External Speaker or the sound is muted by pressing the MUTE button.

Signal Information (digital channels only)

Unlike analogue channels, which can vary in reception quality from snowy to clear, digital (HDTV) channels have either perfect reception quality or you will not receive them at all. So, unlike analogue channels, you cannot fine tune a digital channel. You can, however, adjust your antenna to improve the reception of available digital channels.
