FE-1A SELF DIAGNOSTIC SOFTWARE
The identification of errors within the FE-1A chassis is triggered in one of two ways :- 1: Busy or 2: Device failure to respo nd 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 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.

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 following adjustments in this 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.
5. DC Power supply.

2.[Moving vertically], adjust the V.STAT magnet so that the
Red, Green and Blue points are on top of each other at the

3.If the H.ST AT 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
