Pixel Defects
It should be pointed out to customers that products such as Plasma Display & LCD
TV use display technologies that may occasionally have pixels (or dots) missing or
permanently lit. This does not necessarily indicate a fault. It is important that
prospective customers are advised of this specification and are happy that this type
of technology is suitable for their intended use of the product. Also, please be aware
that displays may take up to 3 months to settle down and pixel failure can occur at
any time within the product's life. There is no guarantee that a perfect screen at the
time of purchase, with no permanently lit or dead pixels, will not be subject to pixel
loss at a later date.
Any customers requesting service for pixel defects, when, in the opinion of Manufacturer,
the product is within specification, will be referred back to the supplying dealer.
Manufacturer will not accept units back for credit for pixel drop out if the display is
within specification.
