В четвърти пост на половината теми за отделните марки има пояснение как се проверява за мъртви пиксели. Има и линк с политиката на отделните фирми по въпроса.
Производител Гаранция Dead Pixels
..............................................................................................................LG 2 години 26": > 4 pixels
32" до 42": > 5 pixels
47"+: > 7 pixelsPanasonic 2 години The definition of a defect pixel is as follows, dead pixel [not lit] lit pixel [always lit] pair defect [adjacent pixels both defect] Defects distance – distance between two defect pixels [5 cms]
With pixel problems the screen is looked at as two zones. Zone B is the 25% of the screen from the top, sides and base inwards. Zone A is in the middle of that zone.
Zone A may have a maximum of 3 single defect red or blue pixels, no lit pixels [pixel is lit always] and no pair defect pixels [adjacent two pixels are both defect]
Zone B may have a maximum of 6 single defect pixels [red, green and blue] no lit pixels, no pair defect pixels. Defects distance for zone B is 5cms.
The screen would therefore need to have equal or more than the accepted level of defect pixels as outlined above to be considered by your dealer/retailer for a warranty replacement option.Samsung 2 години The dead pixel warranty applies when your TFT-LCD/LED/PDP & Monitors contains more than 7 dead pixels within the standard warranty period of your TFT-LCD Monitor which SAMSUNG will exchange the LCD panel/module, provided that the defective unit is returned to SAMSUNG complete with full accessories and original packaging.
Zero Bright Defect (ZBD) only applies when it occurs within 7 working days from purchased date, regardless of dot quantity, the defective LCD panel/module shall be replace by SAMSUNG.
Bright Dot Defect occurs when pixels are always lit or "ON". Black Dot Defect occurs when pixels are always dark or "OFF".Sharp 3 години Case by Case Sony 2 години >3

. Сонито с какво например е по-добро или лошо от самсунга? Целя се към 40", не че нещо, ама така ми хрумна. И не знам искам ли 3д, дори не знам какво е и как се гледа. На 3д кино не съм стъпвал и няма да стъпя.
