SELF DIAGNOSTIC FUNCTION

The units in this manual contain a self-diagnostic function. If an error occurs, the STANDBY/TIMER lamp will automatically begin to flash. The number of times the lamp flashes translates to a probable source of the problem. A definition of the STANDBY/TIMER lamp flash indicators is listed in the instruction manual for the user's knowledge and reference. If an error symptom cannot be reproduced, the remote commander can be used to review the failure occurrence data stored in memory to reveal past problems and how often these problems occur.

1.

DIAGNOSTIC TEST INDICATORS

When an errors occurs, the STANDBY/TIMER lamp will flash a set number of times to indicate the possible cause of the problem. If there is more than one error, the lamp will identify the first of the problem areas. Result for all of the following diagnostic items are displayed on screen. No error has occured if the screen displays a "0". Diagnostic Item Description · Power does not turn on No. of times Self-diagnostic STANDBY/TIMER display/Diagnostic lamp flashes result Does not light -- Probable Cause Location · Power cord is not plugged in. · Fuse is burned out F4601 (F) · H.OUT Q511 is shorted.

SELF-DIAGNOSTIC SCREEN DISPLAY

For errors with symptoms such as "power sometimes shuts off" or "screen sometimes goes out" that cannot be confirmed, it is possible to bring up past occurances of failure for confirmation on the screen: [To Bring Up Screen Test] In standby mode, press buttons on the remote commander sequentially in rapid succession as shown below: [Screen display] / channel [5] / Sound volume [-] / Power ON Note that this differs from entering the service mode (mode volume [+]).

Self-Diagnosis screen display
SELF DIAGNOSTIC 002 : 000 003 : 000 004 : 000 005 : 001 101 : 000 Numeral "0" means that no fault has been detected.

Numeral "1" means a fault has been detected.

5.

HANDLING OF SELF-DIAGNOSTIC SCREEN DISPLAY

Since the diagnostic results displayed on the screen are not automatically cleared, always check the self-diagnostic screen during repairs. When you have completed the repairs, clear the result display to "0". Unless the result display is cleared to "0", the self-diagnostic function will not be able to detect subsequent faults after completion of the repairs. [Clearing the result display] To clear the result display to "0", press buttons on the remote commander sequentially as shown below when the diagnostic screen is being displayed. Channel [8] / 0 [Quitting Self-diagnostic screen] To quit the entire self-diagnostic screen, turn off the power switch on the remote commander or the main unit.

If Q604 go to ON and the voltage to pin 18 of IC301 should go down when V.SYNC is more than seven verticals in a period, the unit will automatically turn off. Occurs when an absence of the vertical deflection pulse is detected by Q509 and IC001 shut down the power supply. Occurs when an overcurrent on V drive line is detected by Q507. Power supply will be shut down when detect this by IC001. If the RGB levels* do not balance or become low level within 5 seconds, this error will be detected by IC301. TV will stay on, but there will be no picture. * (Refers to the RGB levels of the AKB detection Ref pulse that detects IK.)

HOW TO HANDLE AN ANODE-CAP
1 Do not damage the surface of anode-caps with sharp shaped objects. 2 Do not press the rubber too hard so as not to damage the inside of anode-cap. A metal fitting called the shatter-hook terminal is built into the rubber. 3 Do not turn the foot of rubber over too hard. The shatter-hook terminal will stick out or damage the rubber.

SECTION 3 SET-UP ADJUSTMENTS

· ·

The following adjustments should be made when a complete realignment is required or a new picture tube is installed. These adjustments should be performed with rated power supply voltage unless otherwise noted.

Perform the adjustments in the following order : 1. Beam Landing 2. Convergence 3. Focus 4. White Balance Note : Test Equipment Required. 1. Color-bar/Pattern Generator 2. Degausser 3. Oscilloscope

Controls and switches should be set as follows unless otherwise noted: PICTURE control ........................................................... normal BRIGHTNESS control ................................................... normal

................................................................................................................................................................................................................................

Preparation : · In order to reduce the influence of geomagnetism on the set's · picture tube, face it east or west. Switch on the set's power and degauss with the degausser.

Note: Neck Assy is exactly behind DY (no gap between Neck Assy and DY)

Fig. 3-2

3. Set the pattern generator raster signal to a green raster. 4. Move the deflection yoke to the rear and adjust with the purity control so that the green is at the center and the blue and the red take up equally sized areas on each side. (See Figures 3-1 through 3-3.) 5. Move the deflection yoke forward and adjust so that the entire screen is green. (See Figure 3-1.) 6. Switch the raster signal to blue, then to red and verify the condition. 7. When the position of the deflection yoke has been decided, fasten the deflection yoke with the screws and DY spacers. 8. If the beam does not land correctly in all the corners, use a magnet to adjust it. (See Figure 3-4.)

4-3. PICTURE QUALITY ADJUSTMENTS SUB COLOR ADJUSTMENT
1. Input a PAL color-bar. 2. Set to the following condition: PICTURE 100%, BRIGHTNESS 50%, COLOR 50% 3. Connect an oscilloscope to pin 1 (B OUT) of CN305, A board. 4. Set to Service Mode and select SAJ 3 `SCL' with 1 and 4 of the commander then adjust to VB2=VB3=VB4 with 3 and 6. 5. Press [MUTING] ¡ - of the commander to write the data. 6. Adjust SAJ 3 `SCL' as step 2 to 5 when receiving NTSC colorbar.

BELL FILTER ADJUSTMENT
1. Input SECAM color-bar signal. 2. Connect the dual-trace oscilloscope to the pin 9 (R-Y) of CN303 (not mounted). 3. Adjust SERVICE MODE, ITEMS `SBF' as shown below.

4-4. A BOARD ADJUSTMENT AFTER IC003 (MEMORY) REPLACEMENT
When replacing IC003 (MEMORY), be sure to change IC001 (µCOM) to the following new IC at the same time. IC001(µ-CON):CXP86449-614S
VB1 VB2 VB3 VB4 VB2 = VB3 = VB4

1. Enter to Service Mode. 2. Press commander buttons 5 and - (Data Initialize), and 2 and - (Data Copy) to initialize the data. 3. Call each item number and check if the respective screen shows the normal picture. In cases where items are not well adjusted, rectify the items with fine adjustment. Write the data per each item number ([MUTING] +-). 4. Select item numbers "OPB0" (OP1), "OPB1" (OP2) and "OPB2" (OP3) and respectively set the bit per model with command buttons 3 and 6. 5. Press commander buttons 8 and - (Test Normal) to return to the data that was set on the shipment from the factory. (This will also cancel Service Mode.)

SUB HUE ADJUSTMENT
1. Select Video 1. 2. Input a NTSC color-bar, video into Video 1. 3. Set the following condition: PICTURE 100%, BRIGHTNESS 50%, COLOR 50% 4. Connect an oscilloscope to pin 1 (B OUT) of CN305, A board. 5. Select SAJ 1 `SHU' with 1 and 4 of the commander by setting to Service Mode and adjust to VB1=VB2=VB3=VB4 with 3 and 6.

VB1 VB2

VB3 VB4

VB1 = VB2 = VB3 = VB4

6. Press [MUTING] ¡ - of the commander to write the data.
