Lead Free Soldered Boards
example 1
The circuit boards listed below [Table 1] used in these models may 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.

It is strongly recommended to use Lead Free Solder material in order to guarantee optimal quality of new solder joints. Lead Free Solder is available under the following part numbers :
Partnumber 7-640-005-19 7-640-005-20 7-640-005-21 7-640-005-22 7-640-005-23 7-640-005-24 7-640-005-25 7-640-005-26

Remarks 0.25Kg 0.50Kg 0.50Kg 0.25Kg 1.00Kg 1.00Kg 1.00Kg 1.00Kg
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.

WARNING (UK Models only)
The flexible mains lead is supplied connected to a B.S. 1363 fused plug having a fuse of 5 AMP rating. Should the fuse need to be replaced, use a 5AMP FUSE approved by ASTA to BS 1362, ie one that carries the ASA mark. T
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.
How to replace the fuse. Open the fuse compartment with a screwdriver blade and replace the fuse.
FUSE
When an alternative type of plug is used, it should be fitted with a 5 AMP FUSE, otherwise the circuit should be protected by a 5AMP FUSE at the distribution board.

AE-6BA SELF DIAGNOSTIC SOFTWARE
The identification of errors within the AE-6BA 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 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) See table 1, non fatal errors are reported using this method. Each time the software detects an error it is stored within the NVM. See Table 2.

Remote Control Configuration for VCR or DVD
In it's default condition this remote control will operate the basic functions of this Sony TV, Sony DVDs and most Sony VCRs. To control VCRs and DVDs of other manufacturers (and some Sony VCR models), the remote control needs to be configured.
Teletext is an information service transmitted by most TV stations. The index page of the teletext service (usually page 100) gives you information on how to use the service. To operate teletext, use the remote control buttons as indicated below. fig. 2
Teletext errors may occur if you use a channel (TV Broadcast) with a weak signal.
To do this: · Before you start, look up the 3 digit code for your brand of DVD or VCR from the list below. On those brands that have more than one code, enter the first code number. · Sony will endeavour to update the software according to market changes. Therefore, please refer to the code table included with the remote control for latest code set. · A small label is added inside the battery door to allow you to record your brand codes.

How to handle the Anode-Cap
1. 2. 3. 4. To prevent damaging the surface of the anode-cap do not use sharp materials. Do not apply too great a pressure on the rubber, as this may cause damage to the anode connector. A metal fitting called a shatter hook terminal is fitted inside the rubber cap. Do not turn the rubber foot over excessively, this may cause damage if the shatter hook sticks out.

REMOVAL AND REPLACEMENT OF THE MAIN-BRACKET BOTTOM PLATES.
For safety reasons, on no account should the plates be removed and not refitted after servicing. (2) REFITTING THE PLATES Because the plates differ in size it is important that the correct plates are refitted in their original location. Please note that the plates need to be rotated 180 degrees from their cut position to allow the tabs to be fitted into their catch positions.
(1) REMOVING THE PLATES
In the event of servicing being required to the solder side of the printed wiring boards, the bottom plates fitted to the main chassis bracket require to be removed. This is performed by cutting the gates with a sharp wire cutter at the locations indicated by the arrows.
Note : There are 2 plates fitted to the main bracket. Only remove the necessary plate to gain access to the printed wiring board.

SECTION 3 SET-UP ADJUSTMENTS
· · ·
When complete readjustment is necessary or a new picture tube is installed, carry out the following adjustments. Unless there are specific instructions to the contrary, carry out these adjustments with the rated power supply. Unless there are specific instructions to the contrary, set the controls and switches to the following settings : Contrast .................................. normal
Carry out the adjustments in the following order : 3-1. Beam Landing. 3-2. Convergence. 3-3. Focus. 3-4. White Balance. Note : Test equipment required. 1. Color bar/pattern generator. 2. Degausser. 3. Oscilloscope. 4. Digital multimeter.
Brightness .................................. normal
3-1. Beam Landing
Preparation : 1. 2. In order to reduce the influence of geomagnetism on the set's picture tube, face it in an easterly or westerly direction. Switch on the TV set's power and degauss with a degausser. (2) Landing Note : Before carrying out the following adjustments adjust the magnets as indicated [See Fig.3-4]. 1. Input a crosshatch signal from the signal generator. 2. Rough-adjust the focus and horizontal convergence. 3. Switch from the crosshatch pattern to an all-red pattern. 4. Move the deflection yoke backwards and adjust with the purity magnet so that the red is at the centre and it aligns symmetrically [See Fig.3-5]. 5. Move the deflection yoke forward to the point where the entire screen just becomes red [Mark its position]. 6. Move the deflection yoke further forward until the screen just changes colour at the edges. [Mark its position] 7. Position the deflection yoke between the two marks indicated above. 8. Input a crosshatch pattern from the pattern generator and rotate the deflection yoke so that the horizontal lines are parallel with the top and bottom of the screen. 9. When the position of the deflection yoke has been determined, fasten it with its fixing screw. 10. Switch the pattern generator to green then blue and confirm the purity. 11. If the beam does not land correctly in all the corners of the screen, use disk magnets to correct it. [Confirm the corner landing forgreen and blue]
(1) Adjustment of Correction Magnet for Y-Splitting Axis. 1. 2. 3. 4. 5. 6. Input a crosshatch signal from the pattern generator. Set the Picture control to minimum and confirm that the Brightness control is set to normal. Position the neck assembly as indicated in Fig.3-2. Loosen the deflection yoke fixing screw. Move the deflection yoke as far forward as is possible. Adjust the upper and lower pin symmetrically by opening or closing the Y-splitting axis correction magnets located on the neck assembly. [See Fig 3-3] Return the deflection yoke to its original position and re-tighten its fixing screw.
