WARNINGS AND CAUTIONS
CAUTION
These servicing instructions are for use by qualifi ed 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 qualifi ed to do so.
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.
• Disconnect all cables when carrying the TV.
WARNING!!
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.
!
 
SAFETY-RELATED COMPONENT WARNING!!
Components identifi ed by shading and ! mark on the exploded views are critical for safe operation. 
Replace all components with Sony parts whose part numbers appear as shown in this manual or in supplements published by Sony. It is essential that 
all critical parts be replaced only with the part number specifi ed in this manual to prevent electric shock, fi re, or other hazard.
Circuit adjustments that are critical for safe operation are identifi ed in this manual. 
Follow these procedures whenever critical components are replaced or improper operation is suspected. 
NOTE: Do not modify the original design without obtaining written permission from the manufacturer or you will void the original parts and labor 
guarantee.
HANDLING THE GLASS ASSEMBLY
Use the following precautionary guidelines when replacing the Glass Assembly to avoid material degradation or screen coating degradation, and 
ensure that dust, dirt, or fi ngerprints are not left between the glass and the LCD panel.
 
Replace the Glass Assembly in a brightly lit and clean room.  
 
Place the replacement Glass Assembly on a dark cloth to make it easier to see dust and dirt particles. 
 
Wear anti static gloves to avoid leaving fi nger prints on the glass.
 
Use a dry, soft MicroFiber cloth, such as a lint free polishing cloth, to gently wipe the glass to remove any dust or dirt 
particles. 
 
If the glass needs additional cleaning, slightly moisten the cloth with a diluted mild soap or mild detergent solution, or use 
a compressed air duster (spray can type). 
 
After replacing the Glass Assembly, verify there are no dark spots or fi nger prints visible on the screen.
CAUTION
 
Do Not
 use paper towels, any type of abrasive pad, rags, rubber or vinyl materials to clean the screen. Using these 
materials could easily scratch the screen which may result in permanent damage.
 
Do Not
 se any cleaning product containing alkaline/acid cleaner, scouring powder, or volatile solvent, such as alcohol, 
ammonia, benzene, thinner or insecticide. Using any of these harsh cleaners may result in permanent damage to the 
screen.
 
Do Not 
spray water or detergent directly onto the TV screen . If liquid drips into the bottom of the screen it may cause a 
failure.

SAFETY-RELATED COMPONENT WARNING
There are critical components used in LCD color TVs that are important for safety. These components are identifi ed 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 
specifi ed in the electrical parts list to prevent electric shock, fi re, 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. 
USE CAUTION WHEN HANDLING THE LCD PANEL
When repairing the LCD panel, be sure you are grounded by using a wrist band.
When installing the LCD panel on a wall, the LCD panel must be secured using the 4 mounting holes on the rear cover. 
To avoid damaging the LCD panel:
do not press on the panel or frame edge to avoid the risk of electric shock.
  do not scratch or press on the panel with any sharp objects.
  do not leave the module in high temperatures or in areas of high humidity for an extended period of time.
  do not expose the LCD panel to direct sunlight.
  avoid contact with water. It may cause a short circuit within the module. 
  disconnect the AC adapter when replacing the backlight (CCFL) or inverter circuit. 
(High voltage occurs at the inverter circuit at 650Vrms.) 
  always clean the LCD panel with a soft cloth material.
  use care when handling the wires or connectors of the inverter circuit. Damaging the wires may cause a short. 
  protect the panel from ESD to avoid damaging the electronic circuit (C-MOS). 
  During the repair, DO NOT leave the Power On for more than 1 hour while the TV is face down on a cloth.
