Self-Check Function for TV Section

The self-check feature is designed to check if a particular component is functioning and
it does not actually diagnose the problem .For example "Tuner Check OK" doesn't'
necessarily mean that it is OK. It pings or selectively addresses that particular device
2
via the I Bus to determine if it exists. The same holds true for the Global Core IC's, the
MTS, the Sound circuit, and the Audio/Video switches. However, it should be noted that
the displayed results could be misleading by indicating that it is OK.
The troubleshooting section of this document is intended to provide the necessary
guidance and assistance in the fault isolation of a particular problem and will serve as a
diagnostic tool for troubleshooting.
