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.

!

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  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.

When  repairing  the  LCD  panel,  be  sure  you  are  grounded  by
using a wrist band.

When repairing the LCD panel on the wall, the LCD panel must
be secured using the 4 mounting holes on the rear cover.

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.

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).
