When moist gets into LED package because of high humidity, ‘Line
defect’ can be caused by electrical short inside of LED Package.
For keeping the best quality of products during installation, please refer
to the below cautions.
-If the condition meets one of the below cases at least, dehumidification MUST be
processed. Do not play any contents on the screen before dehumidification finishes.
∙Case when vacuum packaging is already unsealed before unpacking products.
∙Case when environment condition is worse than Samsung working condition (0°C~40°C/10~80%RH).
∙Case when it elapses longer than 7 days after unpacking them, even though the environment condition
satisfies Samsung working condition (0°C~40°C/10~80%RH).
∙Case when production date on the label elapses more than 6 months, even though vacuum packaging is
sealed.
∙Case when volatile chemicals such as oil paint, solvent are used in same place of installation.
(You can refer to Product Information and Precautions for Installation part in detail.)
-If the screen needs dehumidification on installation, MUST follow the directions of next page.

How to install the screen in the case that dehumidification is necessary
※ Before finishing the directions explained in next pages, never play other contents or use them.
※ If the installation site has higher humidity, it is highly recommended to use dehumidifier.
(If A/C turned off after working hour, it may make humidity higher and cause line defects.)
※ Chilled air from A/C should never touch LED surface directly.
※ If thermo-hygrometer is equipped on the site while the screen is installed, it is useful to analyze
the cause of line defects.
1. Play a specific pattern of LSM program without any cabinets.
(This pattern should be used. If other pattern is used, it can cause line defects.)
2. Inspect cabinets with darker solid patterns(W/R/G/B) and turn off cabinets.
(It should take less than 30 seconds to show each solid patter and you can refer to ‘Process of
Screen check’ category in detail.)
①Select S-Box and Test Pattern ②Set darker gray pattern among various patterns.
