These servicing instructions are for use by qualified service personnel only. To reduce the risk of electric shock, do not perform any 

servicing other than that contained in the operating instructions unless you are qualified to do so.

An isolation transformer should be used during any service to avoid possible shock hazard, because of live chassis. The chassis of this 

receiver is directly connected to the AC power line.

There are critical components used in LCD color TVs that are important for safety. These components are identified with shading and 

! 

mark on the schematic diagrams and the electrical parts list. It is essential that these critical parts be replaced only with the part 

number specified in the electrical parts list to prevent electric shock, fire, or other hazard.

NOTE: Do not modify the original design without obtaining written permission from the manufacturer or you will void the original parts 

and labor guarantee.

•  Disconnect all cables when carrying the TV.

•  Carry the TV with the adequate number of people; larger size TVs require two or more people.

•  Correct hand placement while carrying the TV is very important for safety and to avoid damage.

8)  Use care when handling the wires or connectors 

of the inverter circuit. Damaging the wires may 

cause a short.

9)  Protect the panel from ESD to avoid damaging 

the electronic circuit (C-MOS).

10)  During the repair,

 DO NOT leave the Power On 

for more than 1 hour

 while the TV is face down 

on a cloth.

To avoid damaging the LCD panel: 
1)  Do not press on the panel or frame edge to avoid the risk of electric shock.
2)  Do not scratch or press on the panel with any sharp objects.
3)  Do not leave the module in high temperatures or in areas of high humidity for an extended period of 

time.

4)  Do not expose the LCD panel to direct sunlight.
5)  Avoid contact with water. It may cause a short circuit within the module.
6)  Disconnect the AC power when replacing the backlight (CCFL) or inverter circuit. 
 

(High voltage occurs at the inverter circuit at 650Vrms.)

7)  Always clean the LCD panel with a soft cloth material.
