5042 Error about projector cooling fan speed report
01 Code display
As a major cooling component of electronic equipment, whether the fan is running well or not directly determines the cooling effect of the electronic equipment. A bad fan may affect the heat dissipation of the equipment components, or cause the equipment to be unable to run.There are many error codes related to the fan speed of the projector, among which the DP2K-C series generally have 5042, 5043, 5053, 5063, 5072, 5073, 5082, 5083, 5103, 5113, 5123, 5143, 5153, 6123, etc., but these troubleshooting and solution methods are basically the same.
02 Related Knowledge
These codes are mainly related to cooler mirror fans, engine fans, heat exchanger fans, projection lamp cathode fans, SMPS fans, projection lamp backside fans, electronics fans, ICP fans, and so on. Specific information is listed below:The fan is connected through a signal backplane, powered by the SMPS, and its speed is monitored and controlled through the fan control board.
03 Adverse Condition
When the fan assembly rotates at a low speed, the status indicator at the rear of the projector shows yellow, and when the fan assembly rotates at too low a speed, the indicator at the rear of the projector turns red, and it is not possible to light the projector. The fan is generally characterized by low or too low rotation speed; abnormal rotation noise and stop rotation.
05 Bad reasons
1、Fan obstructed
2、Loose fan
3, Poor fan line contact
4、Bad fan
5、Fan has reached the service life
6, poor contact of the fan control board
7, Fan control board software version is low
8, bad fan control board
9, signal backplane bad (very low probability)
06 solution
In the whole repair, often involved in the repair of the contents of the general five: 1, check whether the fan is blocked; 2, check the fan at the connecting wire is poor contact; 3, check the fan and signal base plate at the connecting wire; 4, replace the fan to rule out their own bad; 5, plug and replace the fan control board.To make it easier for you to view the fan speed item information, the location of each fan connection cable is listed below.

In the operation of the equipment, observe whether there is a strange noise from the fan; after opening the equipment, observe whether there is too much dust and grease attached to the fan; whether the fan blade is in contact with the nearby wiring; whether the rotation speed is even; whether the fan is fixed tightly; plug and unplug the fan connecting cable, restart the equipment and observe whether the problem is solved; replace the corresponding fan to check whether it has been solved; check the version information of the projector; plug and unplug the fan control board and replace it to see whether it has been solved. Check the projector version information; plug and replace the fan control board to see if the problem has been solved.
Cinema should be based on the projector type of wind speed required to reasonably configure the exhaust fan, wind speed is too large, easy to make the internal fan is forced to accelerate the operation of the equipment, resulting in internal damage to the fan; projection staff in the daily use of equipment, should pay attention to the correct operation of the equipment, do not frequently switch the xenon lamp operation, which will force some of the fans to fluctuate between low and high, is not conducive to the normal use of the fan; usually focus on the daily maintenance of the equipment clean and timely maintenance of equipment A, B, maintenance. Equipment for A, B maintenance, in the removal of projector fan dust should use a soft brush and vacuum cleaner, do not use a strong hair dryer or air pump; in the installation of the electronic board box air dust filter, should pay attention to the direction of the filter and the internal line, do not make the connection line contact fan blades.
