Troubleshooting and Maintenance
Troubleshooting Your Computer
If one or more display pixels look bad
TFT display manufacturing is a highly precise but imperfect technology, and manufacturers cannot produce displays that are cosmetically perfect. Most, if not all, TFT displays exhibit some level of cosmetic imperfection. These cosmetic imperfections may be visible under varying display conditions, and can appear as bright, dim, or dark spots. This issue is common across all vendors supplying TFT displays in their products and is not specific to this notebook display.
Our notebook TFT displays meet or exceed all of our standards for cosmetic quality of TFT displays. We do not warrant that the displays will be free of cosmetic imperfections. TFT displays can have a small number of cosmetic imperfections and still conform to our cosmetic quality specifications, including the following:
•No more than 6 pixels remain on (always one color, such as white, red, green, or blue dots).
•No more than 6 pixels remain off (always dark).
•No more than a total of 8 pixels stuck on or off.
•No other stuck pixel within 15 mm of a stuck pixel.
