Section 7 - Troubleshooting The 960L; Common Problems And Their Solutions - Lexicon 960L Owner's Manual

Common Problems and
Their Solutions
My 960L will not "power-up" when I press the stand-
by switch on the front panel.
Make sure that the main power switch, located on
the rear of the 960L, is in the on position. If not, set
the main power switch to the on position and press
the standby switch on the front panel of the 960L.
The 960L should then power up.
I'm having trouble seeing my LARC2 screen.
Try adjusting the LCD contrast by turning the con-
trast knob located on the rear panel of the LARC2.
I'm running a cable length greater than 100 ft.
between my 960L and LARC2 and the LARC2 does
not function properly.
A cable length greater than 100ft between the 960L
and a LARC2 requires that the LARC2 be powered
by an external power supply in order to function
properly.
My 960L seems to be running very hot.
Verify that the system fans are running and that air
filters are not blocked. Check the fan mounted on
the processor of the Main PC card and the fan
mounted on the right side of the chassis. Verify that
they are not spinning in slow motion or not spinning
at all. Additionally, the filter for the fan mounted on
the right side of the chassis should be clean and
dust free. Remove the filter periodically and wash it
with water and a mild detergent. Be sure to rinse
and dry it thoroughly before reinstalling.
My 960L seems to power up but is not operational.
Try restoring the factory default settings. This will
re s t o re the I/O routings, loaded programs, and
machine global mix and I/O settings, for each con-
figuration back to the factory default settings.
Restoring the factory default settings will not erase
the user registers.
