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. For more information on the use of Lead Free Solder, please refer to http://www.sony-training.com

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 5 AMP 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.
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 5 AMP FUSE at the distribution board.
How to replace the fuse. Open the fuse compartment with a screwdriver blade and replace the fuse.

AE-6D SELF DIAGNOSTIC SOFTWARE
The identification of errors within the AE-6D 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.
Diagnostic Item Description Power does not turn on +B Overcurrent (OCP) Ver tical Deflection stopped

Error Detection Monitor Device acknowledge is used to check IIC errors. Device acknowledge is checked by sending an IIC start sequence during CRT power on. Each device is checked three times, if there is no acknowledge after each attempt, it will be regarded as an error. There are three steps to check for errors. 1. 2. 3. IIC line 0 If all devices except the NVM have errors, IIC line 0 error is displayed. Board check If all devices mounted on one board have errors, board error is displayed. Each device check If IIC line error and board error are not detected then the device with the error is displayed.
The detected errors can be displayed as follows : 1. 2. Error Monitor Menu. Error Reader. 1. Error Monitor Menu

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 some 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 3 plates fitted to the main bracket and secured by3 gates. Only remove the necessary plate to gain access to the printed wiring board.

From time to time dust particles or condensation may get trapped between the glass panel and the TV screen. These instructions will guide you through the steps required to both remove and re-fit the glass panel safely.
Removing the glass panel
NEVER attempt to remove the glass panel on your own - for safety reasons Sony recommends that two people carry out the following procedure at all times.
1
Support the bottom of the glass panel as shown AT ALL TIMES.
Trinitron
2
Push the clips located on the underside of the TV, as shown, to release the glass panel.
3
Whilst pushing the release clip, slide the glass panel up.
4
Supporting the glass panel, tilt it away from the TV.
5
Carefully remove the glass panel and place it safely in an upright position. To avoid injury or damage, do not leave it on the floor.
6
Clean both sides of the glass and the TV screen. Use a soft, damp, lint free cloth. Do not use any chemical solutions or abrasive cleaners.
Re-fitting the glass panel
NEVER attempt to re-fit the glass panel on your own - for safety reasons Sony recommends that two people carry out the following procedure at all times.
1
Lift the glass, and move toward the TV.
2
Insert the bottom locating pins of the glass panel into the keyhole slots on the TV.
3
Tilt the glass panel forwards at the top to engage all the locating pins, then push forward firmly to secure.
Locating pin While still maintaining forward pressure to the bottom of the glass, carefully slide the glass down until it locks. CAUTION Before removing your hands check that you are unable to move the glass. When correctly fitted, the plastic rib shown in the drawing below should not be visible.

Safety Note
The glass panel supplied complies with all relevant safety regulations. However, should the glass become damaged at any time, it is strongly recommended that a replacement is obtained from an authorised Sony dealer.

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 : .................... 80% [or remote control normal] 50%
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.

1. 2. 3. Input an all white signal from the pattern generator. Set the Contrast and Brightness to normal. Set the pattern generator raster signal to Red. Move the deflection yoke forward and adjust with the purity control so that the Red is at the centre and the Blue and Green take up equally sized areas on each side of the screen. [See Fig.3-1 - 3-3]. Move the deflection yoke backwards and adjust so that the entire screen becomes Red. [See Fig.3-1] Switch the raster signal to Blue, then to Green and verify the condition. When the position of the deflection yoke has been determined, fasten the deflection yoke with the screws. If the beam does not land correctly in all the corners, use a magnet to correct it.
