Lead Free Soldered Boards

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 :

91-500-046-7mm3.0gK52.0 02-500-046-7mm4.0gK05.0 12-500-046-7mm5.0gK05.0 22-500-046-7mm6.0gK52.0 32-500-046-7mm8.0gK00.1 42-500-046-7mm0.1gK00.1 52-500-046-7mm2.1gK00.1 62-500-046-7mm6.1gK00.1

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

AE-6B SELF DIAGNOSTIC SOFTWARE

The identification of errors within the AE-6B 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.

WARNING:

BEFORE REMOVING

THE ANODE CAP

High voltage remains in the CRT even after the power is disconnected. To avoid electric shock, discharge CRT before attempting to remove the anode cap. Short between anode and CRT coated earth ground strap.

Coated Earth Ground 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 tentioners.

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.]

Removal of the Anode-Cap

* REMOVING PROCEDURES.

Turn up one side of the rubber cap in the direction indicated by the arrow a

2 Using a thumb pull up the rubber cap firmly in the direction indicated by the arrow b

How to handle the Anode-Cap

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

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

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

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

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

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

3-1. Beam Landing

Preparation :

1. In order to reduce the influence of geomagnetism on the set’s picture 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 the neck assembly. [See Fig 3-3]

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

Fig.3-1

Y-splitting axis correction magnet

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.

(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]

Caution :

High voltages are present on the Deflection yoke terminals - take care when handling the Deflection yoke whilst carrying out adjustments.
