NOTES

About screen defects

High precision technology is used in the making of LCD panels but there may be dark spots (points that do not illuminate) and bright spots (points that are too bright) in some cases. These do not indicate a malfunction.

About residual images

In some cases, residual images may remain after the short-term display of still images and another image is displayed, but these will disappear and return to normalcy. This is not a malfunction.

About the panel screen

LCD displays display images by illuminating phosphor inside the panel. Because of this, the temperature of the panel surface may rise in some cases.Also, LCD displays are made of finely processed glass. A reinforced glass filter is not installed over the LCD panel surface so avoid strong impact because of danger of glass breakage.

About using in a low ambient temperature

The response speed of LCD panel becomes slow as ambient temperatre falls. This feature may cause residual images in some cases, but this is not a malfunction. It will return to normalcy in a litlle while after the temperature becomes normal.
