HOW TO HANDLE THE ANODE-CAP
To prevent damaging the surface of the anode-cap do not use sharp materials. Do not apply too great a pressure on the rubber, as this may cause damage to the anode connector. A metal fitting called a shatter hook terminal is fitted inside the rubber cap. Do not turn the rubber foot over excessively this may cause damage if the shatter hook sticks out.

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 Brightness ............... 80% [or remote control normal] ............... 50%
Carry out the following adjustments in this order :
3-1. 3-2. 3-3. 3-4. Beam Landing Convergence White balance Focus Test equipment required 1. Color bar/pattern generator. 2. Degausser. 3. Oscilloscope. 4. Digital multimeter. 5. DC Power supply.
· ·
Note :
Preparation:
1. 2. In order to reduce the influence of geomagnetism on the set's picture tube, face it in an easterly or westerly direction. Switch on the TV set's power and degauss with the degausser.

For 29" models align the neck assy as indicated below. Purity Control
3-1. BEAM LANDING
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]. Fig. 3-3

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.
How to enter into Table 2
