FE-2 SELF DIAGNOSTIC SOFTWARE

The identification of errors within the FE-2 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.

Connecting a VCR:

To connect a VCR, please refer to the section “Connecting the aerial and VCR” of this instruction manual. We

recommend you connect your VCR using a scart lead. If you do not have a scart lead, tune in the VCR test signal

to the TV programme number “0” by using the “Manual Programme Preset” option. (for details of how to manually

programme these presets, see page 13, step a).

Connecting a VCR that supports Smartlink:

Smartlink is a direct link between the TV set and the VCR. For more information on Smartlink, please refer to the

instruction manual of your VCR.If you use a VCR that supports Smartlink, please connect the VCR to the TV using

a Scart lead to the Scart 2/ F.

If you have connected a decoder to the Scart 2/ or through a

VCR connected to this Scart:

Select the “Manual Programme Preset” option in the “Set Up” menu and after entering the “Decoder**” option,

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.

4. Digital multimeter.
