CAUTION

Lead Free Soldered Boards

The circuit boards listed below [Table 1] used in these modelsmay have been processed using Lead Free Solder. The boards areidentified by the LF logo located close to the board designatione.g. F1, H1 etc [ see examples ]. The servicing of these boardsrequires special precautions to be taken as outlined below.

Table 1

example 1

example 2

It is strongly recommended to use Lead Free Solder material in order to guarantee optimal quality of new solder joints. Lead Free Solder isavailable 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. Thisrequires 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

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 theevent 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 continuousflashing 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 relevantdevice number will be displayed through the LED (Series of flashes which must be counted) See table 1, non fatal errors are reported using thismethod. Each time the software detects an error it is stored within the NVM. See Table 2.

Table 1How to enter into Table 2

1. Turn on the main power switch of the TV set.2. Program Remote Commander for Operation in Service

Mode. [See Page 22].3. Press ‘AUX/VIDEO’ ‘AUX/VIDEO’ > ‘MENU’ on the

Remote Commander.4. Using the Remote Commander, Scroll to the ‘Error’ item

using the down arrow key, then press the right arrowkey.

5. The following table will be displayed indicating the errorcount.

Table 2

Note: To clear the error count data press ‘80’ on the Remote commander.

How to handle the Anode-Cap

1. To prevent damaging the surface of the anode-cap do not usesharp materials.

2. Do not apply too great a pressure on the rubber, as this may causedamage to the anode connector.

3. A metal fitting called a shatter hook terminal is fitted inside therubber cap.

4. Do not turn the rubber foot over excessively, this may causedamage if the shatter hook sticks out.

Removal of the Anode-Cap

2-8. Picture Tube Removal

WARNING:BEFORE REMOVING

THE ANODE CAP

High voltage remains in the CRT evenafter the power is disconnected. Toavoid electric shock, discharge CRTbefore attempting to remove the anodecap. Short between anode and CRTcoated earth ground strap.

Coated EarthGround Strap

1. Discharge the anode of the CRT and remove the anode cap. 2. Unplug all interconnecting leads from the Deflection yoke, neck

assy, degaussing coils and CRT grounding strap. 3. Remove the C Board from the CRT. 4. Remove the chassis assembly. 5. Loosen the Neck assembly fixing screw and remove. 6. Loosen the Deflection yoke fixing screw and remove. 7. Place the set with the CRT face down on a cushion and remove

the Degaussing Coil holders. 8. Remove the Degaussing Coils. 9. Remove the CRT grounding strap and spring tensioners. 10. Unscrew the four CRT fixing screws [ located on each CRT

corner ] and remove the CRT.[Take care not to handle the CRT by the neck.]

• When complete readjustment is necessary or a new picture tubeis installed, carry out the following adjustments.

• Unless there are specific instructions to the contrary, carry outthese adjustments with the rated power supply.

• Unless there are specific instructions to the contrary, set thecontrols and switches to the following settings :

Contrast .................................. normal

Brightness .................................. normal

Preparation :

1. In order to reduce the influence of geomagnetism on the set’spicture tube, face it in an easterly or westerly direction.

2. Switch on the TV set’s power and degauss with a degausser.

(1) Adjustment of Correction Magnet for Y-Splitting Axis.

1. Input a crosshatch signal from the pattern generator.2. Set the Picture control to minimum and confirm that the

Brightness control is set to normal.3. Position the neck assembly as indicated in Fig.3-2.4. Loosen the deflection yoke fixing screw.5. Move the deflection yoke as far forward as is possible.6. Adjust the upper and lower pin symmetrically by opening or

closing the Y-splitting axis correction magnets located on theneck assembly. [See Fig 3-3]

7. Return the deflection yoke to its original position and re-tightenits fixing screw.

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.

Fig.3-1

(2) Landing

Note : Before carrying out the following adjustments adjust themagnets 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 alignssymmetrically [See Fig.3-5].

5. Move the deflection yoke forward to the point where the entirescreen just becomes red [Mark its position].

6. Move the deflection yoke further forward until the screen justchanges colour at the edges. [Mark its position]

7. Position the deflection yoke between the two marks indicatedabove.

8. Input a crosshatch pattern from the pattern generator and rotatethe deflection yoke so that the horizontal lines are parallel withthe 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 thepurity.

11. If the beam does not land correctly in all the corners of thescreen, use disk magnets to correct it. [Confirm the cornerlanding forgreen and blue]

Caution :

High voltages are present on the Deflection yoke terminals - take carewhen handling the Deflection yoke whilst carrying outadjustments.
