Cause and remedy
•
Is power supply plug unplugged from the outlet?
•
If power will not go on with the remote control, is the power supply of the TV "Off"?
•
Is battery exhausted, or is battery polarity wrong?
•
Is the remote control receiver illuminated with strong light from a fluorescent
lamp etc.?
•
Are you using the special-purpose remote control that come with this equipment?
(The unit will not operate with another remote control.)
•
Is there deterioration, breakage or disconnection of the antenna or antenna wire?
•
Is the antenna wire connected correctly?
•
Is the system affected (by radio wave interference or induced electromagnetic
waves) by external sources (automobiles or trains, high-voltage wires, neon,
motors, magnetized steel frame, or iron rain shutters, etc.)?
➠Turn off the power supply, and try changing the equipment setup location. If
that has no effect, separate magnet-proofing will be required.
•
Is the antenna direction shifted?
•
Are reflected electromagnetic waves being received from mountains or buildings?
•
Is the equipment being affected by another TV (electromagnetic interference)?
➠Changing the TV setup location may lead to improvement.
•
Is channel fine tuning correct?
•
Has the screen display button been pressed?
➠Press the "Screen display button" again.
If the system is switched to external input and there is no external signal
video, the number will disappear.
•
This occurs when the signal for driving the liquid crystal is lost, and is not a
malfunction.
•
The screen is darkened for a moment to conceal noise generated when changing
channels.
•
If the screen and audio are not abnormal, this sound is caused by slight expansion
and contraction of the cabinet due to changes in room temperature. It has no
effect on performance.
•
When input is switched to "video input", this may occur if there is no signal at the
video/audio input terminal.
•
With video software wider than 16:9 (cinema vision size software etc.) there are
parts at the top and bottom of the screen where there is no image.
•
Has the screen position adjustment been left shifted?
➠Adjust the screen position.
