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 SOCKET.
When an alternative type of plug is used, it should be fitted with a

AE-5A SELF DIAGNOSTIC SOFTWARE
The identification of errors within the AE-5A 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 a 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.

Error Detection Monitor
Device acknowledge is used to check IIC errors. Device acknowledge is checked by sending an IIC start sequence during CRT power on. Each device is checked three times, if there is no acknowledge after each attempt, it will be regarded as an error. There are three steps to check for errors.
1. IIC line 0 If all devices except the NVM have errors, IIC line 0 error is displayed.
2. Board check If all devices mounted on one board have errors, board error is displayed.
3. Each device check If IIC line error and board error are not detected then the device with the error is displayed.
The detected errors can be displayed as follows :
1. Error Monitor Menu.
2. Error Reader.

2. Error Reader Display
The error reader display is connected to the service connector to read actual error codes. The part number for the error reader display is S-188-900-10. Once an error has been detected it will then be displayed on the two digit error reader. The errors displayed refer to the following table.

SECTION 2 DISASSEMBLY
2-1. Rear Cover Removal
Remove the rear cover fixing screws indicated. Take care when removing the rear cover not to damage the speaker cables [Disconnect the speaker connector] as speakers are fitted inside the rear cover.
2-2. Speaker Connector Disconnection
Before completely removing the rear cover disconnect the speaker connector which is located on the inside.
2-3. Chassis Removal and Refitting
To remove lift the main bracket rear slightly and slide the chassis away from the beznet. Ensure that the interconnecting leads are released from their purse locks to prevent damage being caused.
When refitting the chassis ensure that the main bracket is located in the beznet guide slots before sliding the chassis forwards. Refit the interconnecting leads in their respective purse locks.

How to handle the Anode-Cap
1. To prevent damaging the surface of the anode-cap do not use sharp materials.
2. Do not apply too great a pressure on the rubber, as this may cause damage to the anode connector.
3. A metal fitting called a shatter hook terminal is fitted inside the rubber cap.
4. Do not turn the rubber foot over excessively, this may cause damage if the shatter hook sticks out.

Because the plates differ in size it is important that the correct plates are refitted in their original
location.

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 .................................. normal
Brightness .................................. normal
3-1. Beam Landing
Preparation :
1. In order to reduce the influence of geomagnetism on the set’s picture tube, face it in an easterly or westerly direction.
2. Switch on the TV set’s power and degauss with a degausser.
(1) Adjustment of Neck Assembly and Y-Splitting Axis.
1. Position the neck assembly as indicated in Fig.3-2.
2. Loosen the deflection yoke fixing screw.
6. Position the Y-splitting axis correction magnets located on the neck assembly as indicated in Fig 3-1.
Fig.3-1
Y-splitting axis correction magnet
Carry out the adjustments in the following 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.
4. Move the deflection yoke backwards and adjust with the purity magnet so that the red is at the centre and it aligns symmetrically [See Fig.3-6].
5. Move the deflection yoke forward to the point where the entire screen just becomes red [Mark its position].
6. Move the deflection yoke further forward until the screen just changes colour at the edges. [Mark its position]
7. Position the deflection yoke between the two marks indicated above.
8. Input a crosshatch pattern from the pattern generator and rotate the deflection yoke so that the horizontal lines are parallel with the top and bottom of the screen.
9. When the position of the deflection yoke has been determined, fasten it with its fixing screw.
10. Adjust the upper and lower pin symmetrically by tilting the DY up and down then insert a DY wedge at the top. Use the Y- splitting axis magnets to finely adjust the pin balance. [Fig.3-3].
11. Adjust the H-trap by moving the DY left or right. Insert DY wedges at top and bottom left and top and bottom right. Finely adjust using the H-trap VR on the DY assembly. [See Fig.3-4].
12. Switch the pattern generator to green then blue and confirm the purity.
13. If the beam does not land correctly in all the corners of the screen, use disk magnets to correct it. [Confirm the corner landing for green and blue]
Caution :
High voltages are present on the Deflection yoke terminals - take care when handling the Deflection yoke whilst carrying out adjustments.
(2) Landing
Note : Before carrying out the following adjustments adjust the
magnets as indicated below [See Fig.3-5].
1. Input a crosshatch signal from the signal generator.
2. Rough-adjust the focus and horizontal convergence.
3. Switch from the crosshatch pattern to an all-red pattern.

The menu contains a list with all the available models of this software to set up the TV set in an easy way. The selection of a model is setting data for its features and hardware resources which cannot be detected by the automatic power on H/W detection as well as a special model byte to get an unique model identification for models which cannot be differed by features and hardware resources (e.g. KV-28FC60 and KV-28FC60Z)
Before data is set, the user will be asked if he really wants to set a new model. If the user agrees, automatically the destination setting menu is shown.
