TROUBLESHOOTING FLOW CHARTS.

CHART 5-1.
No Audio Troubleshooting
(Sheet 1 of 18)
NOTES
1. Do not confuse audio tone with noise. Audio
tone is 1-kHz signal.
2. The assumption here is that audio is scratchy
or fades in and out one or more times as
VOLUME control is turned. A very weak
audio is diagnosed in Audio Power Trouble-
shooting.
3. If 0.16 vac is present, Monitor Amplifier
A5100 is working, indicating a valid received
audio from A4300. Therefore, 25.5-vdc
power supply to prior stages and to lamp can
be assumed ok,
