Since it
is
difficult to troubleshoot the
main PWB because of chassis
mounted
on
top
of it, it
is
suggested
that
you use
the
service tool
chassi
s
(LCHSS1134CCZZ) which
is
smaller in size. Install this chassis
for trouble-
sho
o
ting purposes
only
.
When

is
repaired, replace with original chassis.
