|Screen is lit but no picture appears; blue screen, complete snow or a picture appears but you hear no sound on every channel; or no light on the screen appears with or without sound.
|"Snow" effect may be accompanied by poor sound. This could be caused by nearby interference or a temporary broadcast problem. Check other channels to see if the television broadcast station is experiencing difficulty.|
|Speckled bands across the picture could be caused by external interference or a heavy-duty appliance running. Turn appliance off or switch channels.|
|Straight or wavy lines appear diagonally. This may be caused by TV malfunctioning or external interference.|
|"Ghosting" double images are caused by signal interference usually on channels used by local stations off cable. Adjust fine tuning. Tighten cable connections.|
|If picture is rolling vertically, adjust vertical hold control.|
|If the picture pulls horizontally, slowly adjust the horizontal hold control. Your television may be receiving too much signal.|
|Picture may be too large or too small for screen vertically or horizontally. Check TV set adjustments.|
