Solution
• Make sure the power cord is plugged in, and then press POWER.
• The remote control batteries may be dead. Replace the batteries or try the front panel buttons.
• Press the RESET button on the TV front panel (page 9).
• Check the antenna/cable connections (Chapter 2).
• Press INPUT on the remote control or TV/VIDEO on the TV front panel and select a valid video input
source (page 67). If no device is connected to any of the inputs on the TV, no picture will display when
you select that particular input source. For device connection details, see Chapter 2.
• Antenna reception may be poor. Use a highly directional outdoor antenna (if applicable).
• The station may have broadcast difficulties. Try another channel.
• Adjust the picture qualities (page 77).
• If you are using a VCR, make sure the TV/VCR button on the remote control is set correctly (page 26).
• If you have two VCRs connected to your TV, do not connect the same VCR to the TV's output and input
connections at the same time (page 18).
• Do not connect a standard video cable and an S-video cable to VIDEO-1 or VIDEO-2 on the TV back (or
VIDEO-3 on the TV front) at the same time (Chapter 2).
• If you are watching a tuned analog channel (off-air broadcast or Cable TV), set the CableClear DNR
feature to AUTO to reduce visible interference in the TV picture (page 78).
• If the Input Selection window does not appear when you press INPUT on the remote control or
TV/VIDEO on the TV front panel, press INPUT or TV/VIDEO a second time, which will change to the next
video input source and display the Input Selection window.
• If you cannot view signals from external devices connected to VIDEO 1, VIDEO 2,
®
VIDEO 3, or ColorStream,
or from channels 3 or 4, make sure the INPUT LOCK is set to OFF (page 90).
• Set the CLOSED CAPTION feature to OFF (page 80).
• The station may have broadcast difficulties. Try another channel.
• Adjust the TINT and/or COLOR (page 77).
• If the red, green, and blue color guns become misaligned, the picture may appear out of focus. Press the
TouchFocus button on the TV front panel to automatically adjust the color convergence, or manually
adjust the color convergence (page 49).
• When the ColorStream signal source is active, the VIDEO OUT terminal outputs blank video. To receive
video from the VIDEO OUT signal, a standard video or S-video IN jack must be used instead of the
ColorStream connections.
• The VIDEO OUT jack will not output the POP picture (pages 18 and 74).
• Make sure you are using a supported or valid memory card format (page 84).
• Make sure you have saved the picture files in the correct file format (page 84).
• The card may be inserted improperly. Remove the card and reinsert it (page 84).
• The memory card may be empty.
• The memory card may be damaged.
• If your HDMI/DVI device is not working, make sure the device is plugged in to the corresponding HDMI
IN port you are selecting. (page 19 and 50)
