Issues Solutions and Explanations
Picture Quality
First of all, please perform the Picture Test and confirm that your TV is properly displaying test image.
(go to MENU - Support - Self Diagnosis - Picture Test ) If the test image is properly displayed, the
poor picture may caused by the source or signal.
The TV image does not look as
good as it did in the store.
•
If you have an analogue cable/set top box, upgrade to a digital set top box. Use HDMI cables to
deliver HD (high definition) picture quality.
• Cable/Satellite subscribers: Try HD stations from the channel line up.
• Aerial connection: Try HD stations after performing Auto tuning.
•
Many HD channels are up scaled from SD (Standard Definition) contents.
•
Adjust the Cable/Set top box video output resolution to 1080i or 720p.
•
Make sure you are watching the TV at the minimum recommended distance based on the size
and definition of the signal.
The picture is distorted:
macroblock error, small block,
dots, pixelization
•
Compression of video contents may cause picture distortion especially in fast moving pictures
such as sports and action movies.
• Low signal level or bad quality can cause picture distortion. This is not a TV issue.
• Mobile phones used close to the TV (cca up to 1m) may cause noise in picture on analogue and
digital TV.
There is poor colour or
brightness.
• Adjust the Picture options in the TV menu. (go to Picture Mode / Colour / Brightness /
Sharpness
)

Saving )

Picture )
There is a dotted line on the
edge of the screen.

When changing channels, the
picture freezes or is distorted
or delayed.
•
If connected with a cable box, please try to reset the cable box. Reconnect the AC cord and wait
until the cable box reboots. It may take up to 20 minutes.

is too low at maximum volume.

The picture is good but there is
no sound.
•
Set the Speaker Select option to TV Speaker in the sound menu.
•
If you are using an external device, make sure the audio cables are connected to the correct
audio input jacks on the TV.
• If you are using an external device, check the device’s audio output option (ex. you may need to
change your cable box’s audio option to HDMI when you have a HDMI connected to your TV).
• If you are using a DVI to HDMI cable, a separate audio cable is required.
• Reboot the connected device by reconnecting the device’s power cable.
The speakers are making an
inappropriate noise.
•
Check the cable connections. Make sure a video cable is not connected to an audio input.
•
For aerial or cable connections, check the signal strength. Low signal level may cause sound
distortion.
