WARNING (KV-29FX20U only)
The flexible mains lead is supplied connected to a B.S. 1363 fused plug having a fuse of 5 AMP capacity. Should the fuse need to be replaced, use a 5 AMP FUSE approved by ASTA to BS 1362, ie one that carries the ASA mark. T IF THE PLUG SUPPLIED WITH THIS APPLIANCE IS NOT SUITABLE FOR THE OUTLET SOCKETS IN YOUR HOME, IT SHOULD BE CUT OFF AND AN APPROPRIATE PLUG FITTED. THE PLUG SEVERED FROM THE MAINS LEAD MUST BE DESTROYED AS A PLUG WITH BARED WIRES IS DANGEROUS IF ENGAGED IN A LIVE OUTLET SOCKET. When an alternative type of plug is used it should be fitted with a 5 AMP FUSE, otherwise the circuit should be protected by a 5 AMP FUSE at the distribution board.
How to replace the fuse. Open the fuse compartment with a screwdriver blade and replace the fuse.

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 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 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.

REMOVAL AND REPLACEMENT OF THE MAIN-BRACKET BOTTOM PLATES.
(1) REMOVING THE PLATES (2)
£
For safety reasons, on no account should the plates be removed and not refitted after servicing.
REFITTING THE PLATES
In the event of servicing being required to the solder side of the A 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 shown and indicated by arrows. Note :There are 2 plates fitted to the main bracket and secured by 4 gates. Only remove the necessary plate to gain access to the printed wiring board.
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 the cut position to allow the tabs to be fitted in the 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 Brightness ............... 80% [or remote control normal] ............... 50% 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.
· ·
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 set's power and degauss with the degausser.

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 Red. 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]. Move the deflection yoke 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 condition. When the position of the deflection yoke has been determined, fasten the deflection yoke with the screws. If the beam does not land correctly in all the corners, use a magnet 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].

· · All capacitors are in µF unless otherwise noted. pF : µµF 50WV or less are not indicated except for electrolytic types. Indication of resistance, which does not have one for rating electrical power, is as follows. Pitch : 5mm Electrical power rating : 1/4W · · Chip resistors are 1/10W All resistors are in ohms. k = 1000 ohms, M = 1000,000 ohms : nonflammable resistor. : fusible resistor. : internal component. : panel designation or adjustment for repair. All variable and adjustable resistors have characteristic curve B, unless otherwise noted. All voltages are in Volts. Readings are taken with a 10Mohm digital mutimeter. Readings are taken with a color bar input signal. Voltage variations may be noted due to normal production tolerences. : B + bus. : B - bus. : RF signal path. : earth - ground. : earth - chassis.
