Pixels Policy
Syntax's D.O.A. Policy for LCD TVs for
Defective Pixels on LCD Panels
(Applicable to the LCD TV sold within USA & Canada only)
TM
Syntax LCD TVs are evaluated at a distance of approximately 50 centimeters
(approximately 20 inches) between the LCD panel and the eyes of the user at a 90 degrees
viewing angle. All LCD panels have been tested to ensure they comply with our factory standards.
Our evaluation is based on the number of defective pixels and the distance between any two
defective pixels. Bright dots are dots that appear bright and unchanged in size when a LCD TV
screen displays under a black pattern; dark dots are dots that appear dark and unchanged in size
when a LCD TV screen is displayed under pure red, green, or blue patterns ( defective pixels ).
Adjacent dots are dots located directly next to each other.
Customers are required to check their LCD panel immediately after purchase. To identify defective
pixels, the LCD panel should be examined under normal operating conditions as mentioned above,
preferably in its native display resolution, and with a 90 degrees viewing angle.
A LCD TV will be considered dead on arrival (D.O.A.) with regards to defective pixels on the LCD panel
when any one of the following criteria is met:
A total of 7 defective pixels including both bright dots and dark dots are present (the typical
30 LCD Television screen has 16.7 million pixels), or
2 or more pairs of adjacent bright dots are present, or
3 adjacent bright dots are present, or
3 adjacent dark dots are present.
In view of customers' concerns about dead pixels, Syntax would like to address that defective pixels
are not ultimately avoidable with the current LCD industry standard panel manufacturing processes.
We always strive to improve our technology and minimize the chance of occurrence of defective pixels
by applying strict screening processes in our factory production processes. However, Syntax cannot
guarantee that a return unit to our customers will be 100% free of defective pixels.
For questions, please call our toll free service number in the USA at 888-SYNTAX-8.
" At SyntaxGroups, a satisfied customer is our most important focus. "
