When the 5 seconds have passed, the backlight error detect function becomes off, the backlight turns off and

At a temporary reset, the count-down does not take place and the following message appears.
(In this case too, the backlight error detect function becomes off, the backlight turns off and the message
disappears in 5 seconds.)

The key functions in the sound only mode setup process and sound only mode process are referred to in
"Table of Key Allocation in Sound Only Mode" and "Table of Key Functions in Sound Only Mode"
4
To turn off the power with the power key, off-timer or no-signal power supply in the sound only mode, first end
the sound only mode, then call the BRIGHT mode, and finally turn off the power.
5
Let's suppose that the power is on and the BRIGHT mode is off. In this case, call the BRIGHT mode first and
then get started.
6
If the BRIGHT mode is turned off with the sound mute, the sound only mode setup process (caution displayed)
goes on with no sound. Once the sound only mode is set up, the sound mute gets cleared (just when the
backlight turns off). The sound volume level at this clearing will be the same as before the sound mute action.
7
To activate the V-CHIP block, make a temporary reset and keep on the caution display until the block is
unlocked. The screen background will be black, not blue.
8
The closed caption is ignored (including the temporary reset).
