Troubleshooting, lamp/fuse replacement
All these possible errors have been covered in
the previous capters.
Therefore, if you are unable to obtain the
desired microscope image, please read the
corresponding chapters of this manual.
Electrical defects
Electrical defects may include:
1. The lamp on the microscope does not work.
2. No voltage is present.
Check the following possible causes:
The On/Off switch does not work
(no illumination):
• Check that all power cords are properly
connected.
• Make sure that the mains voltage is present at
all power outlets used and has not been
disabled with a master switch.
• After you have ruled out all possible external
causes, it is possible that a fuse of the Leica
DM IL microscope or the power unit is
defective.
All Leica instruments are manufactured and
tested with extreme care. However, if you have
cause for complaint, please do not try to make
any intervention on the instrument yourself.
Directly contact your national agency or our
central service department, the Technical
Service in Wetzlar.

Apart from preparation errors (e. g. staining or
wrong specimen vessels) which are beyond the
scope of this manual, there are basically two
categories of defects:
Mechanical defects and
Electrical defects
Mechanical defects
Reference to possible mechanical defects has
already been made in chapters “Setting up“ and
“Operation“.
Basically, these include the improper posi-
tioning of constrast-enhancing accessories, the
maladjustment of light rings or the setting of an
improper condenser level.
