The units in this manual contain a self-diagnostic function. If an error occurs, the STANDBY/TIMER lamp will automati-cally 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 users knowledge and reference. If an errorsymptom cannot be reproduced, the remote commander can be used to review the failure occurrence data stored inmemory 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 theproblem. 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.

5. HANDLING OF SELF-DIAGNOSTIC SCREEN DISPLAY
Since the diagnostic results displayed on the screen are not automatically cleared, always check the self-diagnosticscreen 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 aftercompletion 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 thediagnostic 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.
6. SELF-DIAGNOSTIC CIRCUIT
[+BovercurrentOCP] Occurs when an overcurrent on the +B(135) line is detected by Q500. If Q500 go toON and the voltage to pin 50 of IC301 more than 3.5V when V.SYNC is more thanseven verticals in a period, the unit will automatically turn off.
[Verticaldeflectionstopped] Occurs when an absence of the vertical deflection pulse is detected by Pin 17 andIC001 shut down the power supply.
[Whitebalancefailure] If the RGB levels* do not balance or become low level within 5 seconds, this errorwill 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.)

Preparation :In order to reduce the influence of geomagnetism on theset's picture tube, face it east or west.Switch on the set's power and degauss with the degausser.
3-1. BEAM LANDING
1. Input a white signal with the pattern generator.ContrastBrightness
2. Set the pattern generator raster signal to a green raster.3. Move the deflection yoke to the rear and adjust with the
purity control so that the green is at the center and the blueand the red take up equally sized areas on each side.(See Figures 3-1 through 3-4.)
4. Move the deflection yoke forward and adjust so that theentire screen is green. (See Figure 3-1.)
5. Switch the raster signal to blue, then to red and verify thecondition.
6. When the position of the deflection yoke has been decided,fasten the deflection yoke with the screws and DY spacers.
7. If the beam does not land correctly in all the corners, use amagnet to adjust it.(See Figure 3-4.)
