SAFETY-RELATED COMPONENT WARNING !!

COMPONENTS IDENTIFIED BY SHADING AND MARKED

  

 

 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.

WARNING !!

AN ISOLATION TRANSFORMER SHOULD BE USED DURING
ANY SERVICE WORK TO AVOID POSSIBLE SHOCK HAZARD
DUE TO LIVE CHASSIS, THE CHASSIS OF THIS RECEIVER IS
DIRECTLY CONNECTED TO THE POWER LINE.

The circuit boards used in these models have been processed using
Lead Free Solder. The boards are identified by the LF logo located
close to the board designation e.g. F1, H1 etc [ see examples ]. The
servicing of these boards requires special precautions to be taken as
outlined below.

Lead Free Solder material must be used to comply with environmental requirements of new solder joints. Lead Free Solder is available under
the  following part numbers :

Due to the higher melting point of Lead Free Solder the soldering iron tip temperature needs to be set to 370 degrees centigrade. This requires
soldering equipment capable of accurate temperature control coupled with a good heat recovery characteristics.

For more information on the use of Lead Free Solder, please refer to  http://www.sony-training.com

When removing the rear cover it is important to ensure that the top button plate is fixed to the front cabinet and not removed with the rear cover.
This is to avoid breaking the cable connected to the switch button board. It is also important to remember that whilst removing the rear cover it
is kept parallel to the LCD plane.
