SECTION 1

SELF DIAGNOSIS FUNCTION

1. Summary of Self-Diagnosis Function

• This device includes a self-diagnosis function.

• In case of abnormalities, the TIMER/STANDBY indicator automatically blinks. It is possible to predict the abnormality location by the number of blinks. The Instruction Manual describes blinking of the TIMER/STANDBY indicator.

• If the symptom is not reproduced sometimes in case of a malfunction, there is recording of whether a malfunction was generated or not. Operate the remote command to confirm the matter on the screen and to predict the location of the abnormality.

2. Diagnosis Items and Prediction of Malfunction Location

• When a malfunction occurs the TIMER/STANDBY indicator only blinks for one of the following diagnosis items. In case of two or more malfunctions, the item which first occurred blinks. If the malfunctions occurred simultaneously, the item with the lower blink count blinks first.

• The screen display displays the results regarding all the diagnosis items listed below. The display “ 0 ” means that no malfunctions occurred.

4. Self-diagnosis screen displays

• In cases of malfunctions where it is not possible to determine the symptom such as when the power goes off occasionally or when the screen disappears occasionally, there is a screen display on whether the malfunction occurred or not in the past (and whether the detection circuit operated or not) in order to allow confirmation.

• Quickly press the remote command button in the following order from the standby state.

OCP Low B and +B line detect DET SHORT, and shut-down POWER ON RELAY.

Reset by turning power on/off. In case of +B is loaded approx. 1.3A or more, microcomputer detects it via IC651.

OVP In case of +B becomes approx. 150V or more, POWER ON RELAY shuts down and microcomputer detects it via IC651.

Reset by turning power on/off just the same as OCP.

V Stop In case of microcomputer detects 2 seconds or more interval of V Pulse, Reference Pulse turns off by turning off the picture

signal in YC Jungle IC (IC206).

After the picture signal turns off, V Pulse is regenerated 2 seconds or more, the picture signal turns on. AKB IK detection. Makes LED blinking in case of microcomputer doesn’t detect IK returns of IC206 CXA2147Q 30 seconds or more. H Stop In case of HV becomes 33kV or more, IC502 detects it and shut-down H Drive Pulse.

Microcomputer receives H Stop data from IC206 and makes LED blinking. Audio In case of DC component overlaps the output of Audio Amp., microcomputer detects it and makes LED blinking.

Microcomputer forces to shut down the power.

1. Select RED KEY or PINCUSHION with the 1 and 4 keys on the remote commander and adjust while tracking each other alternately.

2. Adjust the red crosshatch lines go straight horizontally and overlaps the green lines with the joystick on the remote commander.

Note : These are required when either severe miss-adjustment or

data loss occurred.

[BLUE REGISTRATION ADJUSTMENT]

1. Remove the lens cap from the blue picture lens to show full color.

2. Press 3 key on the remote commander to shift the RED mode to the BLU mode.

3. Adjust BLU CENT, BLU SKEW, BLU SIZE, BLU LIN, BLU KEY and BLU PIN in the same procedure of the red registration adjustment.

[FINAL CHECK]

1. Store the new adjustment (offset) value on the remote control by pressing [MUTING] and [ENTER].

2. Press the FLASH FOCUS button on the front panel. (The Offset value is now automatically stored.)

3. Check that no error message appears. If an error message appears, recheck.

Note: In case of replacing CRTs, adjust the set-up adjustments

(items 3-1 to 3-8) and the registration adjustment (item 3-10). In case of replacing two or three CRTs at the same time, replace and adjust one by one.

1. Press 9 key on the remote commander to shift to the fine adjustment mode. The red cursor (in the RED mode) appears on the center of the screen.

2. Use the 1 and 4 keys or the joystick on the remote commander, move the cursor everywhere you want to adjust and adjust with the joystick on the remote commander.

3-11. AUTO REGISTRATION ERROR CODE LIST

If an error code is displayed after the set has been fully adjusted, correctly, please check the following items: position, tilt and sizing. If either of these adjustments are off, even slightly, the auto-registration pattern will not hit the four sensors properly. This occurs when the internal generator patterns is being flashed on the screen for the sensors to read. Therefore, auto registration (called auto-focus) cannot operate properly causing an error code to be displayed. In order for this function to operate properly, correct position, tilt and size must be adjusted properly.

if necessary re-adjust.

: C517 : C517, C521, C522

IC654, L504 T502, T504 (FBT) D.Y, A board, G board

OPERATION CHECK

1. Connect a HV static voltmeter to the unconnected plug of the high-voltage block. (Fig.5-1)

2. Power on the set.

3. Receive the dot signal. (PICTURE and BRIGHTNESS to minimum)

4. Check that the HV static voltmeter is

reading 31.00

+0.95

kVdc.

HV Regulation adjustment

1. Connect a HV static voltmeter to the unconnected plug of the hight-voltage block.

2. Power on the set.

3. Receive the dot signal. (PICTURE and BRIGHTNESS to minimum)

4. If anode voltage is 31.95kV or higher, replace C517 of 470PF/ 2kV with that of 680PF/2kV , and check if the v oltage is within the standard range.

5. If anode voltage is 29.66kV or lower , replace C517 of 470PF/ 2kV with that of 100PF/2kV , and check if the v oltage is within the standard range.

Remove the cap off from the unused terminal and cpmmect a static voltmeter there.

5-2. HV HOLD DOWN CIRCUIT OPERATION

CHECK AND ADJUSTMENT

When replacing the following components marked with on the schematic diagram always check hold-down voltage

and if necessary re-adjust.

: R536, R545 : C516, C536

D506, D507, D522 IC206, IC502, IC654 L504, R511, R522, R536, R538, R545, R548, R584 T502, T504 (FBT) D.Y, A board, G board

OPERATION CHECK

1. Remove CN652 connecter.

2. Short-circuit across TP-PROT and ground.

3. Connect a HV static voltmeter to the unconnected plug of the high-voltage block.

4. Connect a 220 Ω/200W variable resistor, across pin 2 and pin 1 of CN652 and connect an external dc power supply unit (200V, class 2A) to pin 3 of CN652.

5. First turn on the external power supply (+B=135V), then turn on the power of the set.

6. Receive the dot signal. (PICTURE and BRIGHTNESS to minimum)

7. Gradually increase the value of the external dc po wer supply and check that the hold-down circuit operates at a static voltmeter reading of 33.5±0.95kVdc when the raster disappears.

HV HOLD-DOWN ADJUSTMENT

1. Repeat steps 1 ~ 7 as above.

2. If hold down voltage is 34.45kV or higher, remove R536, mount a resistor (150kΩ, 1/4W : RN) onto R545 instead, and check again if the hold-down voltage is within the standard range.

3. If hold down voltage is 32.55kV or lower, mount a resistor (220kΩ, 1/4W : RN) onto R536 and check again if the holddown voltage is within the standard range.
