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 use IR Signal Check. ➟ p.35
If okay, then possible infrared sensor trouble.
• 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 (+/–) 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 initial setup before the unit goes into Standby mode.
• Autoprogram 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.
• Make sure Autoprogram has been completed. ➟ p.23
• The selected channel may not be broadcasting.
• When Autoprogram is interrupted and not completed, some channels will not be received. Make sure to complete the
Autoprogram. ➟ p.23
• The selected channel cannot be viewed by the Child and ratings lock setting. ➟ p.26
• The unit requires some kind of antenna Input. An indoor antenna (Digital or VHF / UHF), an external antenna (Digital or VHF / UHF)
or an RF coaxial cable from your wall Cable / Satellite set-top box needs to be plugged into the unit.
• Check if the correct Input mode is selected by pressing SOURCE or using CH + / −. Refer to Watching channels from an external
device. ➟ p.18
• Check the antenna, cable or other Input connection to the unit.
• When using the Component 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 station channel number. These basic numbers used for previous Analog broadcasts. (e.g., Input ch# 30 automatically
changes to ch# 6.1)
• Captions that are delayed a few seconds behind the actual dialog are common for live broadcasts. Most captioning production
companies can display a dialog to maximum of 220 words per minute. If a dialog exceeds that rate, selective editing is used to insure
that the captions remain up-to date with the current TV screen dialog.
• There is no clock function on this unit.
• If a Power failure occurs for longer than 10 seconds the child lock setting is retained, but the PIN code is reset to the default code
0000. Refer to Child and ratings lock. ➟ p.26
