8 Troubleshooting Guide

8.1.

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 on the screen can be used to
confirm the occurrence and to limit the scope for the
defective circuits.
Any programmed channels, channels caption data and
some other user defined settings will be erased and return
to factory setting.
