Troubleshooting Some quick and easy tips to fixing problems yourself. SYMPTOMS Snowy picture and unclear sound. SYMPTOMS POSSIBLE SOLUTIONS • Check your antenna connection or location. • Check your cable input. • Check to see if the TV/VCR button on your VCR has the TV selected. Multiple images or 'ghost shadows.' • Check your antenna direction and/or location. • Check your cable input. • Make sure the cable from your antenna to your TV is properly connected. Interference: Sharp lines across the screen and unclear sound. The following may cause image problems or distortion: Electrical appliances, powerful lights, cars, trucks; computers or portable phones; medical equipment • If possible increase the distance between your TV and the offending appliance. Or shut one of them off. Normal picture but no sound. • Check sound level. • Make sure the TV sound is not muted. • Try another channel. The problem may be the broadcast, not your TV. • Are the Audio cables properly installed? • Are the wires for external speakers (if you have external speakers) properly installed? • Make sure your speakers are turned on inthe Audio menu. • If your audio mode is set to SAP, that channel may not have an SAP program. No picture and unclear sound. • Are you in TV or cable tuning mode, and should be in the other? • Make sure output channels on all A/V equipment are on the same channel (3 or 4). • Check that all connections are tight. No picture and no sound. • Is the AC power cord plugged in? • Check that your AC power outlet works. (Test it by plugging in something else or try another outlet.) • Make sure your brightness and audio controls are set properly. • Try another channel. The problem may be with the broadcast. No color, but the sound is O.K. • Check the color settings in the Video menu. • Try another channel. The problem may be with the broadcast. Picture has a big black box on it, but the sound is O.K. Picture has two horizontal black bars, one on top and one on bottom. Missing Secret code • The Caption option may be in Text mode. Select Caption 1, or OFF in the Captions/Text menu. • Your program is in letterbox. This means that the shape of your TV is a square, but the program is a rectangle. Think of the bars as empty space the program doesn't fill; not picture that's blocked out. Because this format is a direct representation of film as you see it in the movies, you are actually seeing MORE of the program when you see those bars. • If you forget the secret code, press the remote control Button '7', '7', '7' and '7' when the display asks you to enter the secret code.
