incorrectly.
Why are there problems with text?

the main index page of the text service and look for the
User Guide. This will explain the basic operation of
text in some detail.

HDMI TV products, due to adoption of new standards.

● Check the correct input has been AV or COMPONENT.
Why did TV turn off by itself?
● After roughly 15 minutes without any input video signal
in TV mode, the TV will turn off to save power.
