DIAGNOSTIC
FLOWCHARTS
The Diagnostic Flowchart is intended to
be
easy to use and the primary aid when
troubleshooting the Model 5200. Follow the prompts in the order presented.
When
a
question
is
asked, follow the line from the box that best applies to your unit's
condition. When that line terminates with
a
letter inside
a
circle, locate the letter on
a
different page and continue the diagnosis. The flowchart leaves nothing to chance,
it tells you when to perform
a
specific
test
and when to replace components.
SWAP OUT PROCEDURE
At many places in the diagnostic flowchart,
a
box tells you to "swap out" a component,
a
chip,
or
a
number of chips in
a
particular order. The "swap-out" instruction means
that you should replace the indicated components (one
at
a
time) with
a
known-good
component of the same type. The unit should then be tested with the new, known-good
component in place to
see
whether the swap out solved the problem being checked. If
the swap out did fix the problem, leave in the new chip and swapout the next.
Repeat this procedure for the rest of the swapout.
Once the unit properly functions,
reinstall the removed IC's to determine which are actually defective.
NOTE:
If
sockets
or
components
are
rephad,
trim
leads
as
close
to
PC
Board
as
possible
(See
Silkscreen
-
shaded
areas indicate
which
leads
to
trim.
Only
trim
leads
in
shaded
areas
as
close
to
board
as
possible).
REPLACE
IN
ORDER
The "replace in order" instruction means that you should replace the components
indicated in the order listed until the result called out
in
the previous block
is
obtained.
X
-
Some lines terminates with
an
X
inside
a
circle. When this occurs, return to the
beginning of the
test
sequence (Mechanical Check page
7-7).
