TROUBLESHOOTING Please make these simple checks before calling for service. Because charges for TV installation and adjustment of customer controls are not covered under your warranty, these tips can save you time and money. CAUTION: A video source (such as a video game, compact disc interactive [CDI], or TV information channel) that shows a constant nonmoving pattern on the TV screen can cause picture tube damage. When your TV is continuously used with such a source, the pattern of the nonmoving portion of the game (or other source) can leave a permanent image on the picture tube. When you're not using the video source, turn it OFF. Also, regularly alternate the use of such video sources with normal TV viewing. No Power No Picture No Sound • Check the TV power cord. Unplug the TV, wait 10 seconds, then reinsert the plug into the outlet and push the POWER button again. • Check that the outlet is not on a wall switch. • Be sure the fuse is not blown on the AC power strip, if one is being used. • Check antenna connections.

Cleaning and Care • To avoid possible shock hazard, be sure the TV is unplugged from the electrical outlet before cleaning. • When you are cleaning the TV, take care not to scratch or damage the screen surface (avoid wearing jewelry or using anything abrasive). Wipe the front screen with a clean cloth dampened with water. Use even, easy, vertical strokes when cleaning. • Gently wipe the cabinet surfaces with a clean cloth or sponge dampened in a solution of cool, clear water. Use a clean, dry cloth to dry the wiped surfaces. • Never use thinners, insecticide sprays, or other chemicals on or near the cabinet, as they might cause permanent marring of the cabinet finish. 52
