SECTION   GENERAL
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 Soldered Boards
example
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

SECTION   GENERAL
How to replace the fuse.
Open the fuse compartment with
a screwdriver blade and replace
the fuse.
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.
UK PLUG WARNING
LCD PANEL CAUTION
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.

AZ-N SELF DIAGNOSTIC SOFTWARE
The identification of errors within the AZ1-N chassis is triggered in one of two ways :- 1: Busy or 2: Device failure to respond to IIC. In the 
event of one of these situations arising the software will first try to release the bus if busy (Failure to do so will report with a continuous flash-
ing LED) and then communicate with each device in turn to establish if a device is faulty. If a device is found to be faulty the relevant device 
number will be displayed through the LED (Series of flashes which must be counted).
