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. H1 etc [ see example ]. 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

FUSE

WARNING (UK Models only)

The flexible mains lead is supplied connected to a B.S. 1363 fused 
plug having a fuse of the correct rating for the set. Should the fuse 
need to be replaced, use a fuse of the same rating approved by ASTA 
to BS 1362, ie one that carries the 

need to be replaced, use a fuse of the same rating approved by ASTA

, ie one that carries the 

ASA

T

 mark.

 mark.

IF THE PLUG SUPPLIED WITH THIS APPLIANCE IS NOT SUITABLE 
FOR THE OUTLET SOCKETS IN YOUR HOME, IT SHOULD BE CUT 
OFF AND AN APPROPRIATE PLUG FITTED. THE PLUG SEVERED 
FROM THE MAINS LEAD MUST BE DESTROYED AS A PLUG WITH 
BARED WIRES IS DANGEROUS IF ENGAGED IN A LIVE SOCKET.

When an alternative type of plug is used, it should be fitted with the 
correct rating fuse, otherwise the circuit should be protected by the 
same rating fuse at the distribution board.

Whilst working on this product, it is not recommended to lay the TV set face down when powered up, as this can result in panel problems. 
If it is necessary to power up the TV set when face down, the time should be minimised as much as possible.
