Chapter 5 53
• If you’ve connected a device to your A/V receiver, such as a DVD player or satellite receiver, you may experience a slight delay
between the audio heard and the video seen. This occurs because the digital audio is sent directly to the speakers while the video
must be processed inside the TV before it is displayed.
• If the device has Component Video (Y, Pb, Pr) jacks, connect these jacks to the TV’s Y, Pb, Pr jacks to minimize the discrepancy. This
works best if the device supports Progressive Scan technology.
• If necessary, you can connect the device directly to the TV using L/R audio jacks and bypassing the A/V receiver or you can program
an audio delay in the A/V receiver so the audio and video match up (not all audio equipment has the ability to program delays).
Check the Audio/Video Receiver’s manual.
Blank screen
• Make sure you have connected the device to the TV correctly.
• Make sure the device connected to the TV is turned on and tuned to the corresponding Video Input Channel.
• Try another channel, or press the INPUT button.
• When you first turn off your TV, the screen fades from blue to black. Once the screen goes black, the TV’s internal lamp starts its
cool-down cycle. If you try to turn on the TV during the cool-down cycle, the TV turns back on and you’ll hear audio, but the picture
will take a few moments to be displayed.
Unusual sound quality
• Check the Graphic Equalizer, Sound Expansion, SAP and Sound Logic settings.
• Check if SAP is turned on.
• Check that the Audio Lang./ Mode or SAP is set to your language.
Humming or buzzing noise
• The TV is in its lamp cool-down cycle. To prolong the life of the TV’s lamp system, the TV must warm up and cool down properly.
You may notice additional noise during these cycles.
• Maybe the speakers are turned off. Check the FIXED/VARIABLE OUT control panel in the Audio menu.
No picture, sound okay
• If the indicator on the front of the TV is blinking for one minute, the lamp inside of your TV may need to be changed. Refer to the
Power indicator is blinking or flashing section on the previous page for more information.
• You might have tried to turn on the TV during lamp cool-down. Wait a few moments and the picture will be displayed.
No sound, picture okay
• Maybe the sound is muted. Try pressing the volume up button to restore sound.
• Maybe the speakers are turned off in the Audio menu. Check the FIXED/VARIABLE OUT control panel in the Advanced Audio menu.
• If using an S-Video, component or composite video connection, remember to also connect the device’s L and R AUDIO OUT jacks to
the TV’s L and R INPUT jacks.
• Check the Maximum Volume and Startup Volume settings in the Advanced Audio menu.
Channel search finds few channels
• The cable connected to the CABLE/ANTENNA INPUT jack might be loose.
• Your off-air antenna might be getting a weak signal. Move it higher or get a bigger antenna.
• Select all the options in the Channel Search menu, and retry channel search.
Can’t select certain channel
• May be blocked or not approved in the Parental Controls menu.
• If using a VCR, check to make sure the TV/VCR button on the VCR is in the correct mode (press the TV/VCR or INPUT button on
your VCR).
• You usually can’t change channels when a menu is on the screen (press the CLEAR button).
