IMPORTANT NOTES:
1. A small number of missing, discolored, or lit all the time dots or pixels is characteristic of TFT LCD technology due to
manufacturing process for such technology irrespective of manufacturer. If your LCD has defective pixels, it should not be
considered defective.
2. Since LCD Rear PTV incorporates a high pressure lamp to display an image, it may take about one minute for the picture to
become stable, after the power has been turned on. After extended use, the picture may darken, the color may look unusual,
or the lamp "goes out," (burns out). You may hear a "pop" sound when the lamp "goes out." These are common
characteristics of the lamp, and should not be considered defective.
3. LCD Rear PTV incorporates an advanced cooling fan system to prevent from overheating. If you hear the cooling fan, it should
not be considered defective.
4. If you hear a "cracking" sound from the TV cabinet, it is due to the TV's cabinet expanding and contracting due to room
temperature changes. It has no effect on the TV's functions.
