1. 2. 3. Input an all-white signal from the pattern generator. Set the Contrast and Brightness to normal. Set the pattern generator raster signal to all Red. Move the deflection yolk 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]. Move the deflection yolk forward and adjust so that the entire screen becomes Red. [See Fig.3-1]. Switch the raster signal to Blue, then to Green and verify the purity condition. When the position of the deflection yolk has been determined, fasten the deflection yolk with the screws. If the beam does not land correctly in all the corners, use magnets to correct it. [See Fig.3-4].

[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. 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].

Input a Phillips colour pattern Set the picture settings to normal. Adjust the focus control located on the Flyback transformer to bring the centre of the screen into focus. Note :Bring only the centre area of the screen into focus, switch to an all-white pattern and confirm that the magenta ring is hardly noticed. To obtain optimum focus balance the focus setting between optimum screen centre focus and a reduced magenta ring level.

4-3. FE-1 SELF DIAGNOSTIC SOFTWARE
The identification of errors within the FE-1 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 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.
