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
T mark.
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

1
2

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)

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.

For safety reasons, on no account should the plates be
removed and not refitted after servicing.

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 the cut position to
allow the tabs to be fitted in the catch positions.

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.

•

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%

Carry out the following adjustments in this order :
3-1. Beam Landing
3-2. Convergence
3-3. Focus
3-4. White Balance
Note :

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]
