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) Detected Symptoms · Power does not come on. · No power is supplied to the TV. · AC power supply is faulty.
· +B overcurrent (OCP) · Horizontal deflection overdrive

3. STOPPING THE STANDBY/TIMER FLASH
Turn off the power switch on the TV main unit or unplug the power cord from the outlet to stop the STANDBY/TIMER lamp from flashing.
4. 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 [+]).

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 Q500 go to ON and the voltage to pin 50 of IC301 more than 3.5V 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 Pin 17 and IC001 shut down the power supply. 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
KV-PG14M40/PG14M72/L/N KV-PG14P42/G/L/N/PG14P70
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
Perform the adjustments in the following order : 1. Beam Landing 2. Convergence 3. Focus 4. White Balance Note : Test Equipment Required. 1. Pattern Generator 2. Degausser 3. Oscilloscope
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. 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.
Purity control
3-1. BEAM LANDING
1. Input a white signal with the pattern generator. Contrast normal Brightness 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 blue and 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 the entire screen is green. (See Figure 3-1.) 5. Switch the raster signal to blue, then to red and verify the condition. 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 a magnet to adjust it. (See Figure 3-4.)

1. (Moving vertically), adjust the V.STAT magnet so that the red, green and blue dots are on top of each other at the center of the screen. 2. (Moving horizontally), adjust the H.STAT VR control so that the red, green and blue dots are on top of each other at the center of the screen. 3. If the H.STAT variable resistor cannot bring the red, green and blue dots together at the center of the screen, adjust the horizontal convergence with the H.STAT variable resistor and the V.STAT magnet in the manner given below. (In this case, the H.STAT variable resistor and the V.STAT magnet influence each other, so be sure to perform adjustments while tracking.)

3-3. FOCUS ADJUSTMENT
FOCUS adjustment should be completed before W/B adjustment. 1. Receive digital monoscope pattern. 2. Set "Picture Mode" to "DYNAMIC". 3. Adjust focus VR so that the center of screen becomes just focus. 4. Change the receiving signal to white pattern and blue back. 5. Confirm magenta ring is not noticeable. Incase magenta is very obvious, adjust focus VR to take balance of magenta ring and focus.
