In regard to the self-check function
When phenomena like “the power fails from time to time” or “the video/audio fails from time to time” can not be confirmed at the
time of servicing, the self-check function can be used to confirm the occurrence and to limit the scope for the defective circuits.
Also, when “the power fails from time to time”, display of the color bar on the screen can be used confirm the occurrence and to
limit the scope for the defective circuits.
