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.

• Carry the TV with the adequate number of people; larger size TVs require two or more people.
• Correct hand placement while car rying the TV is very importa nt for safety and to avoid  

damage. 

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.

Components identified by shading and ! mark on the schematic diagrams, exploded views, and in the parts list are critical for safe operation. Replace

these components with Sony parts whose part numbers appear as shown in this manual or in supplements published by Sony. Circuit adjustments that

are critical for safe operation are identified in this manual. Follow these procedures whenever critical components are replaced or improper operation is

suspected.

Use the following precautionary guidelines when replacing the Glass Assembly to avoid material degradation or screen coating

degradation, and ensure that dust, dirt, or fingerprints are not left between the glass and the LCD panel.

R

 Replace the Glass Assembly in a brightly lit and clean room.

R

 Place the replacement Glass Assembly on a dark cloth to make it easier to see dust

and dirt particles.

R

 Wear anti static gloves to avoid leaving finger prints on the glass.

R

 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.

R

 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).

R

 After  replacing  the  Glass  Assembly,  verify  there  are  no  dark  spots  or  finger  prints

visible on the screen.

W

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.

W

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.

W
