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.

How to install the screen in the case that dehumidification is necessary.
3. While installing cabinets, S-Box should play only this pattern.
•Check S-Box shows the pattern through monitor connected to S-Box service port.
•After installing each cabinet, check whether the pattern is shown in it.
•OCM cable connection can be checked through this.
•Before turning off S-Box, turn off the cabinets, first.
•After being sure S-Box plays this pattern, turn on the cabinets.
4. After completing installation of cabinets, start 24hr dehumidification process.
5. After finishing 24hr dehumidification process, do edge correction and module calibration.

•Electrical short in package is possible to happen during products are
working.
•For keeping quality of products during installation, please refer below
cautions.
–If one of below case meet during operation, MUST do dehumidification process.
Case when environment condition is exceed operation condition.
Case when products are not operated more than 10 days, even though environment
condition is under operation condition.
–When environment condition is exceed operation condition, products are out of
warranty. Please check environment condition.
–Even products are operating, if the installed place have extra construction such as
interior modification, MUST do dehumidification following installation condition.
–It is possible to happen dew condensation on surface of products, even though working
on operating condition. When happening dew condensation, MUST operate after
cleaning the dew condensation & dehumidification.

Dew condensation due to overcooling
Even though meet with Samsung recommended operation condition, dew
condensation is possible to happen when surface of products is colder than
environment temperature or hot & humid air blow to cooled surface of
products.
(cf : Principle of happening dew on surface of glass which have ice)
Case when dew condensation is happen on products, it is possible to be the
root of defect. In this case, it is possible to be out of warranty.

Do not let cold wind hit the screen directly.
-If cold wind from the screen surface A/C directly touches, condensation may form
depending on the ambient humidity and the temperature of the screen.
-If the A/C and the screen are close, install a wind shield as shown in the figure below
to prevent condensation.
