30 M3L_RXD pin low
31 M3LEN pin low
32 Compact Text RAM test fail
Once every main loop (approximately 200ms OSD mode, 50ms text or menu mode), the micro checks the protection pin (pin 66). If the protection
pin is high 6 successive times, a protection error is diagnosed. The protection pin is not checked during the first 3 - 4 seconds after AC on.
If this error is diagnosed, the respective NVM register will be updated and the set goes straight into diagnostic standby with 2 flashes - no reset is
attempted.
Once every main loop the micro checks the AKB stability by reading the IKR return from the Jungle IC. IKR=1 means that the AKB is stable,
IKR=0 means that the AKB is unstable. If the AKB status is unstable for 10 seconds, an AKB error is diagnosed. AKB stability is not checked
during the first 20 seconds after AC switch on.
If this error is diagnosed, the respective NVM register will be updated and the response LED will flash 5 times continually, but the set will not go
into standby mode. If the AKB status becomes stable, and remains stable for 10 seconds, the LED will stop flashing.
If any of these errors are detected, the respective NVM register will be incremented. The software will then carry on with the power up sequence.

General IIC Device Run-time Errors (Errors 19-23):
Compact Text Run-time Errors (Errors 26, 28, 33 & 34):
MSP and DSP Run-time Errors (Errors 24 & 25):
If any of these errors are detected, the respective NVM register will be incremented and the software will carry on.
NVM Error Description
19 No acknowledge from Jungle when attempting to initialise.
20 No acknowledge from Jungle when attempting to read registers.
21 AV Switch cannot complete reset during initialisation.
22 No acknowledge from AV Switch when attempting to read registers.
23 No acknowledge from NVM when attempting to read or write.
In the case of these errors, the ‘device reset’ pin will be held low for 60ms, causing a hardware reset of Compact Text. Following this reset, a
longer timeout will be allowed for the M3L bus to reco ver. If the error still e xists, the NVM register will be incremented and the software will carry
on.
NVM Error Description
26 M3L_TXD pin low when checking register 81 (implies that no communication was
possible).
28 M3L_TXD pin low when attempting to initialise (implies that no communication was
possible).
33 Compact Text RAM test failed during initialisation of devices.
In the case, the ‘device reset’ pin will be held low for 60ms, causing a hardware reset of Compact Text. Compact T ext will then be re-initialised and
the NVM counter updated. This is the same as for errors 26, 28 and 33 except that the M3L bus timeout is not changed.
NVM Error Description
34 Register 81 check fail, but M3L_TXD pin high (implies that Compact Text has either
reset or become corrupted).
For both these errors, the software will refresh the MSP and DSP registers. If the errors still exist, the NVM counter will be incremented, and the
software will carry on.
NVM Error Description
24 Error 24 can be caused by any of the following :
- After MSP initialisation, Scart Prescale Register check fail (implies that the MSP
has either reset or become corrupted).
- MSP fails to acknowledge reset instruction.
- Scart Prescale Register check fail (implies that the MSP has either reset or
become corrupted).
25 - DSP test byte corrupted (implies that the MSP has either reset or become
corrupted).

Error Display Mode
Error Display Mode is entered by the following sequence of commands :
Standby -> Information -> Digit 5 -> Volume Down -> TV
This mode will display a special menu, which will list all possible errors and the number of occurrances of each error (0 - 255, as stored in the
NVM). There will also be a display of the current error (00 if no error). This display mode will appear as follows :
ERROR DISPLAY MODE
Current Error Code = 00
Error Code Occurrences Error Code Occurrences
2 2 19 0
3 -- 20 0
4 -- 21 0
5 0 22 0

14 0 31 0
15 3 32 0
16 0 33 3
17 0 34 38
18 6
Whilst in this mode, the number of occurences of each error can be reset to 0 by following sequence of Sircs commands: Digit 8 -> Digit 0.
‘TT08’ will also reset this NVM data.
This mode can only be exited by switching off the TV.
The Current Error Code can also be read by using a TV Error Reader (IIC slave address 42H). This de vice simply recei ves 1 data b yte, which is the
error number in binary coded decimal form.

REMOVAL AND REPLACEMENT OF THE MAIN-BRACKET
BOTTOM PLATES.
(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 arrows.
Note :There are 4 plates fitted to the main bracket and secured by 6 gates.
Only remove the necessary plate to gain access to the printed wiring board.
(2) REFITTING THE PLATES
Because the plates differ in size it is important that the correct plates are refitted in
their original location.
The plates are identified by numerical markings on their top side e.g. 1,2
1. Identify the plate by locating its marking.
2. Rotate the plate through 180’ (do not flip over).
3. Locate the corresponding numerical markings indicated on the main
chassis. See Fig 2.
4. Refit the plate as indicated in Fig 3 with the markings located next to each
other.
£
For safety reasons, on no account should the plates be
removed and not refitted after servicing.
In the event of the plates requiring to be removed
at a later stage, this can be achieved by inserting a
screwdriver in the snap-recess indicated as in Fig 4
and lifting 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 ............... 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 set’s power and degauss with the
degausser.
(1) Adjustment of Correction Magnet for Y-Splitting
Axis
1. Input a crosshatch signal from the pattern generator.
2. Set the Picture control to minimum and confirm that the
Brightness control is set to normal.
3. Position the neck assembly as indicated in Fig.3-2.
4. Move the deflection yoke as far forward as is possible.
5. Adjust the upper and lower pin symmetrically by opening or
closing the Y-splitting axis correction magnets located on the
neck assembly.
6. Return the deflection yoke to its original position.
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. Digital multimeter.
4. Oscilloscope.
(2) Landing
Note :Before carrying out the following adjustments
adjust the magnets as indicated below [See Fig.3-3].
1. Input an all-white signal from the pattern generator.
Maximize the picture setting and adjust the Brightness
setting.
2. Rough-adjust the focus and horizontal convergence.
3. Loosen the deflection yoke screws and align the purity
adjustment knob to its central position. [See Fig.3-1].
4. Switch from the all-white pattern to an all-green pattern.
5. Move the deflection yoke backwards and adjust with the
purity magnet so that the green is at the centre and it aligns
symmetrically. [See Fig.3-4].
6. Move the deflection yoke forward and adjust so that the
entire screen becomes green.
7. Switch the raster signal to red, then to blue and verify the
landing condition.
8. When the position of the deflection yoke has been determined,
fasten the deflection yoke with the screw.
9. If the beam does not land correctly in all the corners of the
screen, use magnets to correct it. [See Fig.3-5].
