Is a voltage of about 3.3V
DC applied to pins (3) and
(5) of IC1703?
YES
Is about DC 2.5V applied
between pins (5) and (8) of
IC1704?
YES
Is about DC 2.5V applied
between pins (4) and (3) of
IC8009?
YES
Is there 133-MHz clock
output at pin (6) of IC8010?
Is there 75-MHz clock
output at pin (6) of IC8011?
YES
Is there about DC3V
applied at pin (21) of
IC2002? Do the D0 thru D7
signals appear as pulse
signals on the oscilloscope
screen?
YES
Check IC2002 and its
peripheral circuits.
Check IC8202, IC8203,
IC2601 and their
peripheral circuits.
NO
Check IC1703 and its
peripheral circuits, or IC1702
and its peripheral circuits.
NO
Check IC1704 and its
peripheral circuits.
NO
Is the lamp access lid
open? Is the P2006 (LF)
tight in the socket?
YES
Fully close the lamp access
lid. Or insert the P2006 (LF)
tightly in the socket.
NO
Check IC8010, IC8011 and
their peripheral circuits.
NO
See if the fan is running as
specified. Or check IC8003
and its peripheral circuits.
33
NO
Check IC8009 and its
peripheral circuits.
