BE-3E SELF DIAGNOSTIC SOFTWARE
The errors indicated below can be read using an Error Reader Display (Part Number S-188-900-10) connected to the service connector. Once an error has been detected it will then be displayed on the two digit error reader. During the power up procedure and during normal run time, the micro’s self diagnostic procedures monitor for various errors. Errors displayed refer to the table indicated below.
Error Number Error Description
00 No error (TV Error Reader shows 00 in normal condition) 01 Not allowed (may be confused with Sircs response flash on LED) 02 Protection circuit trip (OCP, OVP & No V-Sync) 03 Reserved for OVP (Included in error 2 for BE-3E) 04 Reserved for No V-Sync (Included in error 2 for BE-3E) 05 AKB 06 IIC Scl Low <Power Up only> 07 IIC Sda Low <Power Up only> 08 IIC Sda & Scl Low <Power Up only> 09 Jungle controller no acknowledge <Power Up only> 10 Video Switch (CXA2040) no acknowledge <Power Up only> 11 Tuner no acknowledge 12 MSP no acknowledge 13 NVM no acknowledge 14 AV switch (CXA2089) no acknowledge (DS20 & DX20) 15 Not used 16 Port Expander (CXA1875) no acknowledge (DS20 & DX20) 17 Not used 18 Dynamic Convergence (CXA8070) no acknowledge 19 Cannot Initialise jungle (after initial power on check OK) - <Chassis Initialisation> 20 Jungle controller response failure after power up check (+9V test) 21 Video Switch (CXA2040) cannot power on reset - <Chassis Initialisation> 22 Video Switch (CXA2040) response failiure after power up check (+9V test) 23 NVM acknowledge fail after initialisation (STBY +5V - same as micro!) 24 MSP run-time failure <May Not Be Fatal - Display On Error Reader> 25 DSP run-time failure <May Not Be Fatal - Display On Error Reader> 26 M3L bus Clock low time out after data send <Run-Time Failure> 27 M3L bus Clock low time out after data send <At Power Up Check> 28 M3L bus Clock low time out after data send <At Initialisation> 29 M3L Txd Low <Power Up Only> 30 M3L Rxd Low <Power Up Only> 31 M3L Enable Low <Power Up Only> 32 Compact Text test fail <Power Up Only> 33 Compact Text does not respond (+5V test) 34 Compact text run-time failure <May Not Be Fatal - Display On Error Reader>

Protection Error (Error 2):
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.
AKB Error (Error 5):
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.

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

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.
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 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.

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].
