Safety is very important. Please read and follow the safety documentation (Safety Booklet) 
separately provided.

Unplug the TV and other connected equipment from the 
wall outlet before you begin cleaning your TV.
•

Wipe the LCD screen gently with a soft cloth.

•

Stubborn stains may be removed with a cloth slightly 
moistened with a solution of mild soap and warm 
water.

•

If using a chemically pretreated cloth, please follow the instruction provided on the 
package.

•

Never use strong solvents such as a thinner, alcohol or benzine for cleaning.

•

Do not plug in the TV into the wall outlet until the moisture from cleaning has 
evaporated.

The TV should also be placed on a stable surface to prevent it from toppling over (see 
page 12). If you have young children or pets at home, check regularly to ensure the TV is 
securely fastened. 

The remote control does 
not function.

select TV Control and then select Home (Menu) or 
Options to control the TV.

The TV and its 
surrounding become 
warm.

• When the TV is used for an extended period of time, the TV 

and its surroundings may become warm to touch. This is not 
a malfunction of the TV.
