Explanation/Solution

Picture quality depends on the signal quality.

Check the antenna/cable connections. Check the antenna location and direction. Check if the antenna is broken or bent.

Check if the antenna has reached the end of its serviceable life. (3-5 years in normal, 1-2 years at the seaside.) Keep the TV away from noise sources, such as cars, motorcycles or hairdryers.

If using 300 Ω twin lead, move the excess lead away from the TV or try using 75Ω coaxial cable instead. Press Picture to select the desired Picture Mode.

Adjust the Picture Mode item in the Picture Settings .

Make sure that the antenna is connected with a 75Ω coaxial cable. Keep the antenna cable away from other connecting cords.

To avoid TV interference, make sure to use an undamaged antenna cable.

Explanation/Solution

Check the volume control. Press the Mute or Vol+ button on the remote control until the muting symbol

disappears from the screen. Disconnect your headphones.

Explanation/Solution

Confirm the PC is correctly connected to the TV from either the PC OUT (with an HD15 cable) or HDMI out. Ensure the output from the PC is one of the formats listed on p.18.

Turn off the PC. Confirm the PC connection and restart the PC. Plug and play will automatically detect the TV and correctly set up PC resolution.

Verify if the Power Management on the PC is activated. Adjust the resolution. Adjust Pitch and Phase.

If the 4:3 Default in the Screen settings is set to other options than Off, the current Wide Mode setting is automatically replaced with the 4:3 default setting when you change the channel or video input. If you want to select the Wide mode from the Zoom on the remote control, set the 4:3 Default to Off in the Screen settings.

Check the Wide options in the Screen settings.

The picture size reduces during the commercials. This is because of the way the provider broadcasts the commercial content. When HD content channels switch to SD contents (commercials), the picture size will reduce and will be surrounded by a black border.

Some wide screen programs are filmed in aspect ratios that are greater than 16:9 (particularly for theatrical releases). When displaying these programs, black bands will appear at the top and bottom of the screen . Programs in 4:3 aspect ratio will have bands on the left and right sides of the screen.

This is because the digital compression of the source content used by certain digital broadcasts and DVDs may cause your TV screen to display fewer details than usual or artifacts (small blocks or dots, pixilation) on the screen. These signal compressions are more visible and depend on the clarity and resolution of the television.

Check the polarity of the batteries or replace the batteries.

Point the remote control at the remote control sensor located at the front of the TV.

Fluorescent lamps can interfere with the operations of your remote control. Turn off fluorescent lamps and try again.

Remove obstacles within effective range of the remote control sensor.
