down
Symptom:
(111) Unit ticks momentary then shuts down.
Solution: Q1801 (stand by regulator on the D board) was replaced during early production with
a metal tap type transistor 2SD1135-C). Although this transistor is not connected to
a heat sink it is mounted next to IC1801's heat sink. Because of it's closeness to the
IC1801 heat sink the metal tap may touch the heat sink. If this should occur re-
mount Q1801 and add a dab of RTV (7-322-065-19) between the transistor and heat
sink.
