Please be careful of the following when perform
servicing.
1. Please protect caution items.
Parts that considered as caution or critical item when
servicing are shown by critical label or seal on cabinet,
chasis, parts etc.
Please make sure to protect these caution notes and
Intruction Manual.
2. Beware with electric shock
Live chassis can caused electric shock because its
connected to the ac power line. Therefore, please use
isolation transformer and gloves when changing parts or
remove plug. Please remember that there is high voltage
during servicing.
3. Use specification parts.
Some parts has its characteristic such as fire retardancy
and voltage value specification. Therefore, please use the
same specification to replace parts. Parts identified by
shading and critical mark on the schematic diagrams,
exploded views, and in the part list are critical for safe
operation. Replace these parts 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 parts are replaced or improper
operation is suspected.
TO INSERT THE MDF CONNECTOR
1
  Press the middle
 
part of the connector
 
to insert till it locks.
2
  Press the right
 
side to confirm it is
 
locked.
3
  Press the left
 
side to confirm it is
 
locked.
The connector might not be properly locked when only pressed from the middle.
Be sure to press both sides to confirm it is properly locked.
4. On a safety as before, attaching parts and leading wiring
by using insulated material such as tube and tape, there
are also parts that taken from printed wiring boards.
Therefore when doing the internal wiring by leading or using
clamper, make sure wires are kept away from sharp edges,
heat sink and high temperature or high pressure parts.
5. Safety after sevicing
For safety, please check whether removed screws, parts
and wires are same as before. And check there is no
deterioration of seviced parts. Please make an insulation
checking between plug and external metal parts.
6. Do not fix internal of power supply board/inverter.
For safety, please do not perform service at the power
supply board or inverter.

➔ off (0.5s) ➔ Green (0.5s) ➔ off (0.5s)
Notes: Green (Power LED is ON/OFF)
In case that AGING_TIMER = 0
Green (3.0s) 
➔ off (3.0s) ➔ Green (3.0s) ➔ off (3.0s)
Notes: Green (Power LED is ON/OFF)
Note:
If set has been put on surface down, brightness surface irregularity is
caused by static electricity. If so be, turn set over or keep it upright
more than 30 seconds. As surface irregularity is vanished away, then
check the set.
