3-13. TROUBLESHOOTING FLOW CHARTS.

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.

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.
