1. The bulb does not light up (except LED light source)
Possible cause: The bulb is not completely cooled, or the bulb has reached the end of its life,
the treatment is as follows
：
Due to abnormal operation, the bulb is not completely cooled down, so let the lamp body
cool down for more than 10 minutes to make the inside completely return to normal state,
and then turn on the power again.
；
Check whether the bulb has reached the end of its life, and replace it with a new one
；
Check whether the bulb and the lighter circuit are leaking, falling off, or having poor
contact
；
Replace with a new lighter.
2. The light beam appears dim
Possible cause: The bulb has been used for a long time or the light path is not clean, the
treatment is as follows
：
Check whether the bulb has reached the end of its life, and replace it with a new one
；
Check whether the optical components or bulbs are clean, and whether there is dust on the
bulbs and other optical components. Regular cleaning and maintenance of the bulbs and
components in the lamps are required.
3. Fuzzy pattern projection
Check whether the electronic focus channel value is suitable for the current projection
distance.
4. The lamps work intermittently
Possible cause: The internal circuit enters the protection state, and the treatment is as
follows
：
Check whether the fan is operating normally or whether it is dirty, causing the internal
temperature of the lamp to rise
；
Check whether the internal temperature control switch is closed
；
Check whether the bulb has reached the end of its service life, and replace it with a new
one.
5. After the lamp is reset normally, it does not accept the control of the console
Possible cause: signal line failure or abnormal lamp parameter setting, the treatment is as
follows
：
Check the start address code and check the connection of the DMX signal line (whether the
signal line cable is intact, and whether the connection of the head is loose)
；
Add signal amplifier, add 120 ohm terminal resistance
；
6. The lamp can't start
Possible cause: bad power line, the treatment is as follows
：
Check whether the fuse on the power input socket is fused, replace the fuse
；
Lamps have poor line contact due to vibration during long-distance transportation
Check the input power, computer board and other plug-in devices.
2. Precautions for use
Check whether the local power supply meets the requirements of the rated voltage of the
