Policy on defec ive pixels
Due to the complexity of the technology used in the manufacture of LCD, TFT and LED screens, it is
possible that some of the pixels that make up the screen may be defec ive. While it is desirable for all
the pixels to func ion correctly, this is not always possible from a produc ion perspec ive. For this rea-
son, Ersax Trade S.L cer i es that its LED TV products meet the criteria of admissible defect described
herein and cer i es that its LED TV screens are class A.
Defec ive pixels
Bright pixel (max.)
Dark pixel (max.)
Maximum permi ted sum of pixels
Double adjacent pixels (max.)
If an LED TV screen has dark or bright pixels, this is only considered to be a fault by Ersax Trade S.L
when the ranges established herein for an LED panel to be considered defec ive are exceeded, thereby
allowing Ersax Trade S.L to manage the replacement or warranty of the panel due to a product non-con-
formance. As a rule and except for limited excep ions, Ersax Trade S.L considered an LED TV product
to be faulty when it has a considerable number of permanently bright or dark pixels. As a reference, an
LCD/LED panel has more than 1 million pixels and a single defec ive pixel is therefore not considered to
cons itute a lack of conformance and cannot be catalogued as a fault, as this circumstance will not a ect
the correct func ioning of the product.
Bright pixel
Dark pixel
Therefore, if an LED screen meets the above criteria, it cannot be changed or repaired as this is not
considered to be a lack of product conformance and cannot be catalogues as a defect or fault.
