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 :

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.

FE-2D SELF DIAGNOSTIC SOFTWARE
The identification of errors within the FE-2D 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.

Many broadcasters now provide a digital text service. Digital text services offer all
the familiar information that analogue (conventional) text services provide but with
the look and feel of a graphically rich website.
The appearance, content and navigation methods of all digital text services are
decided by the broadcaster. For example, digital text from the BBC may look

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.

For safety reasons, on no account should the plates be re-
moved 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.

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 .................... 80% [or remote control normal]
Brightness ................... 50%
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 set’s power and degauss with the degausser.
3-1. Beam Landing
1. Input an all white signal from the pattern generator. Set the
Contrast and Brightness to normal.
2. Set the pattern generator raster signal to Red.
3. 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].
4. Move the deflection yoke backwards and adjust so that the
entire screen becomes Red. [See Fig.3-1]
5. Switch the raster signal to Blue, then to Green and verify
the condition.
6. When the position of the deflection yoke has been
determined, fasten the deflection yoke with the screws.
7. If the beam does not land correctly in all the corners, use a
magnet to correct it. [See Fig.3-4]
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.

2. [Moving vertically], adjust the V.STAT magnet so that the Red, Green and Blue points are on top of each other at the centre of the screen.
3. If the H.STAT variable resistor is unable to bring the Red, Green and Blue points together at the centre of the screen, adjust the horizontal convergence with the H.STAT variable resistor and the V.STAT magnet in the manner indicated below. [In this case, the H.STAT variable resistor and the V.STAT magnet influence each other].
Tilt the V.STAT magnet and adjust the static convergence by
opening or closing the V.STAT magnet.
The movement of the magnets interact with each other and so the respective dot position should be monitored while carrying out this adjustment. Use the H.STAT VR to adjust the Red, Green and Blue dots so that they coincide at the centre of the screen (by moving the dots in the horizontal direction).
