SELF DIAGNOSIS FUNCTION
If no acknowledgement is returned from a device which is turned "ON", the device has a problem.
In this case, one of the LED's responding to the problem device will flicker a defined number of times.
Flickering is operated by lighting the LED's for 60ss each time.
The flickering frequency responding to each failed device is shown below.
NONVOLATILE
Device
Flickering
Frequency
All the devices are checked one after another from the left of the table.
If an error is found, the responding LED will start flickering.
So, if more than 1 device have failed, only the one on the left side will flicker.

Troubleshooting
If you have any problems, read this manual again and
check the countermeasure for each of the symptoms
listed below.
If the problem persists, contact your nearest authorized
service center or dealer.
Snowy picture
Noisy sound
/ Check the antenna.
/ Check the antenna connection on the TV
and on the wall.
Dotted lines or stripes
/ This may be caused by local interference
(e.g. cars, neon signs and hair dryers).
Adjust the antenna for minimum
interference.
Double images or “ghosts”
/ This may be caused by reflections from
nearby mountains or buildings. A highly
directional antenna may improve the
picture.
Notes
• When you switch on the TV, you may hear the “boon” sound
that is caused by the demagnetization of the TV. This does not
indicate a malfunction.
• The picture color may become abnormal if you change the
direction of your TV. To obtain the normal picture color , press
POWER on the TV to switch off the TV for five minutes and
then switch it on again.
No picture
No sound
/ Press POWER.
/ Check the antenna connection.
/ Check the VCR connections.
/ Check the power cord connection.
/ Check the standby mode.
changes in the room temperature
sometimes make the TV cabinet expand or
contract, making a noise. This does not
indicate a malfunction.
Note on the remote commander
• The supplied remote commander is used on several models of
the TV. If you do not find instructions for some controls that
are on the remote commander, that means your TV does not
employ the features of those controls, e.g. TEXT.
Note on the TV SYSTEM button
• The TV SYSTEM button is not used on your TV.
WARNING
Do not install the appliance in a confined space, such as
a bookcase or built-in cabinet.

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.
Controls and switch should be set as follows unless otherwise noted:
PICTURE control........................................................... normal
BRIGHTNESS control................................................... normal
• 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.
Perform the adjustments in order as follows :
1. Beam Landing
2. Convergence
3. Focus
4. White Balance

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 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.

4-2. ADJUSTMENT METHOD
Item Number 08
This explanation uses V-SHIFT as an example.
1. Select 08 V-SHIFT with the [1] and [4] buttons.
2. Raise/lower the data with the [3] and [6] buttons.
3. Select the optimum state. (The standard is 0F for PAL
reception.)
4. Write with the [MUTING] button.
5. Execute the writing with the [0] button. (The WRITE
display returns to green SERVICE.)
Use the same method for Items Number 00-4B. Use [1] and [4] to
select the adjustment item, use [3] and [6] to adjust, write with
[MUTING], then execute the write with [0].

• Standard Data: Those are the standard data values written on the microprocessor. Therefore, the data values of the
modes are stored respectively in the memory.
In case of a device replacement, adjustment by rewriting the data value is necessary for some items.
• 50 ...................... 50 Hz data
• 60 ...................... 60 Hz data
• Standard data listed on the adjustment item table are reference values, therefore it is different for every model.
2. Press commander buttons [5] and [0] (Data Initialize), and [2]
and [0] (Data Copy) to initialize the data.
3. Call each item number, and check if the respective screen shows
the normal picture.
In case some items are not well-adjusted, give them fine
adjustment.
Write the data per each item number ([MUTING] + [0]).
4. Select item numbers “49” (OP0), “4A” (OP1) and "4B" (OP2)
respectively set the bit per model with command buttons [3]
and [6].
5. Press commander buttons [8] and [0] (Test Normal) to retur n to
the data that was set on the shipment from the factory.
