SECTION 1 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

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

Tmark.

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.

AZ1-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).

LED Error Codes and Descriptions

Number of LED

Flashes Error Description Checked Action

02 Power Supply Protection error. In normal and factory mode. Goes into standby.

03 Audio error. In normal and factory mode. Goes into standby.

04 Balancer error. In normal and factory mode. Goes into standby.

05 Panel Error & Panel ID error In normal and factory mode. Goes into standby.

06 Inverter error. In normal and factory mode. Goes into standby.

16 DVB-T/C Demod error. In initialisation state. Adds error to error menu.

18 USB error. In normal and factory mode. Adds error to error menu.

19 CI error. In normal and factory mode. Adds error to error menu.

Resetting Error Codes (OSD Service Menu)

1. If Software version of the set is older than M8R31 (M8.311), update to latest version.

2. Power Off / Power ON.

3. Apply TT19.

4. Apply TT08. TV switches off and then restarts.

5. Conﬁrm error had disappears.

Note: TT19 is necessary if Factory mode is not enabled.

When Factory Mode is enabled “F” is shown on top right of the screen in TT mode.
