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 rele vant 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 T able 2.

REMOV AL AND REPLA CEMENT OF THE MAIN-BRA CKET
BOTT OM PLA TES.
For safety reasons, on no account should the plates be removed and not refitted after servicing.
(1) REMOVING THE PLATES
In the event of servicing being required to the solder side of the D Board printed wiring board, 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.
- 16 -
(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 : T est equipment required.

1. [Moving horizontally], adjust the H.STAT control so that
the Red, Green and Blue points are on top of each other at
the centre of the screen.
Operation of the BMC (Hexapole) magnet.
2. [Moving v ertically], 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.ST AT variable resistor and the V.STA T
magnet influence each other].
• Tilt the V.ST AT magnet and adjust the static convergence by
opening or closing the V.STA T 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.STA T 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).

Geometry Adjustment.
Preparation:
Before starting this adjustment, adjust the horizontal and
vertical static convergence.
1. Remove the deflection yoke spacer.
2. Tilt the deflection yoke as indicated in the figure below and
optimise the geometry.
Tilting the D Y Up and Down will balance the upper and
lower pin adjustment.
Tilting the D Y Left and Right will balance the H-Trap
adjustment.
3. Re-install the deflection yoke spacer.

If you are unable to adjust the corner conver gence properly ,
this can be corrected with the use of permalloy magnets.
