SECTION 1 GENERAL
CAUTION
Lead Free Soldered Boards
example
The circuit boards used in these models have been processed using
Lead Free Solder. The boards are identif ied 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
UK PLUG W ARNING
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
ASA
T
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 APPROPRIA TE 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.

EG1H SELF DIAGNOSTIC SOFTWARE
The identification of errors within the EG1H 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 f irst try to release the bus if busy (Failure to do so will report with a continuous
flashing 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).
Turn off the power switch on the TV main unit or unplug the power cord from the outlet to stop the STANDBY LED for flashing.

SELF-DIAGNOSTIC SCREEN DISPLAY
For errors with symptoms such as “power sometimes shuts off” or “screen sometimes goes out” that cannot be confirmed, it is possible to
bring up past occurrences of failure for confirmation on the screen:
[To Bring Up Screen Test]
In standby mode, press buttons on the remote commander sequentially in rapid succession as shown below:
