Faulty Issue 6: The Gobo wheel, color wheel or CMY module is stuck, or with shaking,stepping
out and out of control performance
Troubleshooting:
◎
The stuck issue is usually caused by the mechanical reasons, such as the Gobo wheel or color
wheel is deformed , the screw is loose etc.
◎
shaking , stepping out or out of control maybe caused by the screw loose and missing, but the
damage of the related chips in the PCB, interior bad cables connection, the damage of motors
are would be the reason of these issue.
Method of confirming the Motor cause
: first, find the corresponding motor cable, for example, the
GOBO wheel is M, find the M position in the PCB. Measure the motor with a multi meter. if the
motor is damaged, replace the motor. If the cable is bad connection, fix it.
◎
Check the space between the small magnet and the sensor, the best distance should be between
1.0-2.0mm, the big distance will case the inaccurate location or asynchronous.

Faulty Issue 7 :The focus or prism has big noise, stuck ,and stepping out.
◎
The focus and prism have sliding parts, if there are some noise, shake, stuck, it's generally caused
by lacking of mechanical lubricant or blocked by massive dust, it needs to be cleaned regularly, and
add heat-resistant and cold-resistant
lubricant
.
◎
The focus stuck may be caused by the motor damage or the screws on the motor are loose or
missing
.
◎
The aging, loose or broken of prism belt would cause the issue of prism and focus ‘s stuck,
stepping out.
◎
The stuck and stepping out: Except the above reasons, the other cause maybe: the damage of
the corresponding chip on the PCB, the bad connection of motor cable, the cable short circuit to
the ground, or the motor damage.
