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.

For errors with symptoms such as “power sometimes shuts off” or “screen sometimes goes out” that cannot be con-
firmed, 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

SELF DIAGNOSTIC

– 6 –

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.

[+B overcurrent ªOCPº]

Occurs when an overcurrent on the +B(135) line is detected by Q500. 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.

[Vertical deflection stopped]

Occurs when an absence of the vertical deflection pulse is detected by Pin 17 and
IC001 shut down the power supply.

[White balance failure]

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.)

• Dangerously high voltages are present inside the TV.
• TV operating voltage: 110 – 240 V AC. (KV-TG21M70)

220 – 240 V AC. (KV-TG21M90/N)

• Do not plug in the power cord until you have completed making all other connections;

otherwise a minimum leakage current might flow through the antenna and other terminals to
ground.

• To avoid battery leakage and damage to the remote, remove the batteries from the remote if

you are not going to use it for several days.  If any liquid that leaks from the batteries touches
you, immediately wash it away with water.

To prevent fire or shock hazard, do not expose
the TV to rain or moisture.

Do not operate the TV if any liquid or solid object
falls into it.  Have it checked immediately by
qualified personnel only.

Do not open the cabinet and the rear cover of the
TV as high voltages and other hazards are
present inside the TV.  Refer servicing and
disposal of the TV to qualified personnel.

Your TV is recommended for home use only.
Do not use the TV in any vehicle or where it may
be subject to excessive dust, heat, moisture or
vibrations.

Do not block the ventilation openings of the TV.
Do not install the TV in a confined space, such
as a bookcase or built-in cabinet.

For children’s safety, do not leave children alone
with the TV.  Do not allow children to climb onto
it.

Clean the TV with a dry and soft cloth.  Do not use
benzine, thinner, or any other chemicals to clean
the TV.  Do not scratch the picture tube.

For your own safety, do not touch any part of the
TV, the power cord and the antenna cable during
lightning storms.

C

To prevent the TV from falling, use the supplied screws, clamps and band to secure the TV.

Screw the band to the TV stand and to the
provided hole at the rear of your TV.

(1) Put a cord or chain through the

clamps.

(2) Screw one clamp to a wall or pillar

and the other clamp to the provided
hole at the rear of your TV.

Note
• Use only the supplied screws.  Use of other screws may damage the TV.

Do not place any objects on the TV.

Do not plug in too many appliances to the same
power socket.  Do not damage the power cord.

Pull the power cord out by the plug.  Do not pull
the power cord itself.  Even if your TV is turned
off, it is still connected to the AC power source
(mains) as long as the power cord is plugged in.
Unplug the TV before moving it or if you are not
going to use it for several days.

Install the TV on a stable TV stand and floor
which can support the TV set weight. Ensure that
the TV stand surface is flat and its area is larger
than the bottom area of the TV.
