Chapter 8: Troubleshooting General troubleshooting Before calling a service technician, please check this chapter for a possible cause of the problem and some solutions you can try. Black box on screen • The Closed Caption feature is set to one of the Text modes (T1, T2, T3, or T4). Set the Closed Caption feature to Off (- page 41). LED indications while in reboot from standby • When you plug the power cord in the red LED will blink until the TV enters standby mode, (plugged in but not powered on). This is normal and is not a sign of malfunction. TV stops responding to controls • If the TV stops responding to the controls on the remote control or TV control panel and you cannot turn off the TV, press and hold the POWER button on the TV control panel for 5 or more seconds to reset the TV. Other problems • If your TV's problem is not addressed in this Troubleshooting section or the recommended solution has not worked, use the Reset Factory Defaults procedure (- page 29). TV will not turn on • Make sure the power cord is plugged in, and then press p. • The remote control batteries may be dead. Replace the batteries or try the control panel buttons. Picture problems General picture problems • Check the antenna/cable connections (- Installation Guide). • Press + on the remote control or TV and select a valid video input source (- page 30). If no device is connected to a particular input on the TV, no picture will display when you select that particular input source. For device connection details, see the Installation Guide. • 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 40). • If you are using a VCR, make sure L on the remote control is set to the correct mode (see item 22 on page 12). • If you have two VCRs connected to your TV, make sure you have not connected the same VCR to the TV's output and input connections at the same time (- Installation Guide). • Do not connect both a standard video cable and an S-video cable to the same set of VIDEO inputs (VIDEO 1, or VIDEO 2) at the same time (- Installation Guide). Noisy picture • If you are watching an tuned analog channel (off-air broadcast or Cable TV), you can set the CableClear® feature to AUTO to reduce visible interference in the TV picture (- page 53). Video Input Selection problems • If the Input Selection window does not appear when you press + on the remote control or TV, press + a second time, which will change to the next video input source and display the Input Selection window. Cannot view external signals or channel 3 or 4 • If you cannot view signals from external devices connected to VIDEO 1, VIDEO 2, or ColorStream®, or from channels 3 or 4, make sure the Input Lock is set to Off (- page 48). Poor color or no color • The station may have broadcast difficulties. Try another channel. • Adjust the Tint and/or Color (- page 40). • When the ColorStream® signal source is active, the VIDEO OUT terminal does not output video. To receive video from the VIDEO OUT terminal, a standard video or S-video IN connection must be used instead of the ColorStream® connections. POP problems • If you label all of the inputs as "Hide," the POP feature will be disabled. If you then attempt to access the POP feature, the message "Not Available" will appear onscreen (- page 38). Poor composite or S-video picture • If the TV is connected to an external A/V device (e.g., DVD player, video game system, set-top box, etc.) try using a ColorStream or HDMI video connection instead. Picture and sound are out of sync • As with all products that contain a digital display, in rare instances, when viewing certain content (e.g.. television broadcasts, video games, DVDs), you may notice that the sound and picture are slightly out of sync. This phenomenon can be caused by various factors including, without limitation, video processing within the TV, video processing in an attached gaming system, and video processing or different compression rates used by broadcasters in their programming. You may want to try one or more of the following suggestions, which may help to reduce the effect of this phenomenon: - If the TV is connected to an A/V receiver that has a programmable audio delay feature, use this feature to help synchronize the sound to the picture. - If you notice this phenomenon only on certain TV channels, please contact your local broadcast, cable, or satellite provider to inform them of this issue.
