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 38.)

•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 autoprogram has been completed. (Refer to “Autoprogram” on page 19.)

•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.

•The selected channel may not be broadcasting.

•When autoprogram is interrupted and not completed, some channels will not be received. Make sure to complete. (Refer to “Autoprogram” on page 19.)

•The selected channel cannot be viewed by the “Child Lock” setting. (Refer to ‘‘Child Lock” on page 27.)

•The unit requires some kind of antenna input. An indoor antenna (VHF /UHF), an external antenna (UHF /VHF) 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 [SOURCE] or using [CH + / -]. (Refer to “Switching Each Input Mode” on page 16.)

•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.

•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.
