Issues Solutions and Explanations

There is a dotted line on the

edge of the screen.

If the Picture Size is set to Screen Fit, change it to 16:9.

Change the cable/satellite box resolution.

The picture is black and white. If you are using an AV composite input, connect the video cable (yellow) to the Green

jack of Component on the product

When changing channels, the

picture freezes or is distorted

or delayed.

If the product is connected to a cable box, try to reset the box. (Disconnect and then

reconnect the AC cord and wait until the cable box reboots. It may take up to 20

minutes.)

Set the output resolution of the cable box to 1080i or 720p.

Sound First, perform the Sound Test to determine if your product audio is operating

properly. (Go to MENU  Support  Self Diagnosis  Sound Test).

If the audio is OK, the sound problem may caused by the source or signal.

There is no sound or the

sound is too low at maximum

volume.

Please check the volume of the device (Cable/Sat Box, DVD, Blu-ray etc.) connected

to your product.

The picture is good but there

is no sound.

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 if you have the box

connected to your product using an HDMI cable.)

If you are using a DVI to HDMI cable, a separate audio cable is required.

If your product has a headphone jack, make sure there is nothing plugged into it.

Reboot the connected device by disconnecting, and then reconnecting device’s

power cable.

The speakers are making an

inappropriate noise.

Check cable connections. Make sure a video cable is not connected to an audio input.

For aerial or cable connections, check the signal information. A low signal level may

cause sound distortion.

Perform the Sound Test feature. (MENU  Support  Self Diagnosis  Sound Test)

RF (Cable / Aerial) Connection

The product is not receiving

all channels.

Make sure the coaxial cable is connected securely.

Please try Setup to add available channels to the channel list. Go to MENU  System

 Setup and wait for all available channels to be stored.

Verify the aerial is positioned correctly.

The picture is distorted:

macro block error, small

block, dots, pixelisation.

The compression of video contents may cause picture distortion, especially with fast

moving pictures such as sports and action movies.

A weak signal can cause picture distortion. This is not a product problem.

Others

Purple/green rolling

horizontal bars and buzzing

noise from the product

speakers with a Component

cable connection.

Remove the left and right audio connections from the Set-Top box. If the buzzing

stops, this indicates that the Set-Top box has a grounding issue. Replace the

Component video cables with an HDMI connection.
