• Check if the input source is HDMI1 / HDMI2 / HDMI3.
• Keep the RF coaxial cable away from other connected cables.
• Adjust the SOUND MODE setting in the SOUND menu, depending on the type of
program you are watching.
• If still have distorted sound, switch off the DTS TruSurround in SOUND menu, then
re-adjust the SOUND MODE setting in the SOUND menu.
• Select the New Password setting in the Lock System menu, then enter the
following master password "8899". The master password clears your previous
password and allows you to enter a new password.
• Check if the disc is correctly inserted.
• Check that the disc is clean.
• Check if there is any obvious damage to the disc.
• Try to play the disc on another DVD to check whether it has content.
• Check if the TV is in DVD mode.
• Select Password in the Preference Page of DVD menu, then enter the following
master DVD password "136900". The master password clears your previous

• Adjust the resolution, horizontal frequency, or vertical frequency.
• Use Auto configure or adjust clock, phase, or H/V position.
• Check the signal cable.
• Reinstall the PC video card.
• You can only record free to air channels.
• You may have you run out of space on your USB storage device. Delete some files or
use another USB storage device.
• Check that there were no recording conflicts from scheduled series recordings.
• It happens sometimes if you have a weak signal. Usually it just means you'll need to
re-scan your digital box or TV. Don't worry, it is easy to do. And once you've done it,
you should get all the Freeview channels available to you. If problems persist you
may need to get your aerial checked. Talk to your retailer or contact your local aerial
installer.
• In most cases, blocking is caused by a reception problem – either the signal is too
weak or there is some kind of interference. Talk to your retailer or contact your local
aerial installer.
• Blocking can also be caused by a digital signal that is too strong. If you are still
experiencing blocking and the signal is strong, consult your local aerial installer for
advice.
