Sample Waveforms
HY/HZ board
The pages that follow contain samples of waveforms that are present when the
unit is in good operating condition. Prior to determining that a board should be
replaced, it is advisable that these waveforms are checked to help achieve the
right conclusion.
Figure 61 is an illustration of the HZ-Board. The board is the interface between
the AV inputs and the D1-Board. When troubleshooting, connect a signal source
to the input terminals and observe the output signals at the connector.
