WARNING (UK Models only)
The flexible mains lead is supplied connected to a B.S. 1363 fused plug having a fuse of 13 AMP rating. Should the fuse need to be replaced, use a 13 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 SOCKET.
How to replace the fuse. Open the fuse compartment with a screwdriver blade and replace the fuse.
FUSE

When an alternative type of plug is used, it should be fitted with a 13 AMP FUSE, otherwise the circuit should be protected by a 13 AMP FUSE at the distribution board.

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.

Diagnostic Item Description Power does not turn on

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. 2. 3. IIC line 0 If all devices except the NVM have errors, IIC line 0 error is displayed. Board check If all devices mounted on one board have errors, board error is displayed. 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. 2. Error Monitor Menu. Error Reader. 1. Error Monitor Menu

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.

Before completely removing the rear cover disconnect the speaker connector which is located on the inside.

2-3. Chassis Removal and Refitting

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.

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.

(2) 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 their cut position to allow the tabs to be fitted into their catch positions.

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

(1) REMOVING THE PLATES

In the event of servicing being required to the solder side of the D 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 indicated by the arrows.

Note : There are 3 plates fitted to the main bracket and secured by3 gates. Only remove the necessary plate to gain access to the printed wiring board.

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

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.

Brightness .................................. normal

3-1. Beam Landing
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 a degausser. (2) Landing Note : Before carrying out the following adjustments adjust the magnets as indicated below [See Fig.3-4]. 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. 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.3-5]. 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. Switch the pattern generator to green then blue and confirm the purity. 11. 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]

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.
