Answer
• Check the antenna or cable connection to the main unit.
• Check the batteries of the remote control.
• Check if there is an obstacle between the infrared sensor window and the
remote control.
• Test the signal output. If OK, then possible infrared sensor trouble.
Refer to "IR Signal Check" on page 56.
• Aim the remote control directly at the infrared sensor window on the
front of the unit.
• Reduce the distance to the unit.
• Re-insert the batteries with their polarities (+/– signs) as indicated.
• When there is an infrared-equipped device such as PC near this unit, it
may interrupt the remote control signal of this unit.
• Move the infrared-equipped device away from this unit, change the angle
of the infrared sensor or turn off the infrared communication function.
• Connect the RF coaxial cable to the unit directly and run the initial setup.
• Make sure to complete the channel scan before turning off the unit.
• Make sure autoscan has been completed.
Refer to "Autoscan" on page 20.
• Autoscan must be completed when you set up the unit for the first
time or move it to a location where previously unavailable channels are
broadcast.
• The selected channel may not be broadcasting.
• When autoscan is interrupted and not completed,
some channels will not be received. Make sure to complete.
Refer to "Autoscan" on page 20.
• The selected channel cannot be viewed by the "Child Lock" setting.
Refer to ''Child Lock" on page 28.
• The unit requires some kind of antenna input. An indoor antenna
(VHF /UHF), an external antenna (VHF /UHF) or an RF coaxial cable from
your wall cable/satellite box needs to be plugged into the unit.
• Check if the right input mode is selected by pressing [INPUT SELECT] or
using [CHANNEL - / + ]. Refer to "Switching Each Input Mode" on page 17.
• Check the antenna or cable connection to the unit.
• When using the Composite Video Connection check that the Green
(Y), Blue (Pb/Cb) and Red (Pr/Cr) connectors are connected to their
corresponding colored jacks on the unit.
• Many digital channels have alternate channel numbers. The unit changes
the numbers automatically to the ones signifying the broadcasting
stations. These are the numbers used for analog broadcasts.
• Clean the disc.
• Ensure the disc is correctly inserted.
• Check if the disc is defective by trying another disc.
• Cancel the parental lock or change the control level.
• Insert a correct disc that plays back on this unit.
• Handle a disc with special care so that it does not have fingerprints,
scratches or dusts on its surface.
• Captions that are delayed a few seconds behind the actual dialogue are
common for live broadcasts. Most captioning production companies can
display a dialogue to maximum of 220 words per minute. If a dialogue
exceeds that rate, selective editing is used to insure that the captions
remain up-to date with the current TV screen dialogue.
• There is no clock function on this unit.
