[Digital Audio-Visual Network News] The Spring Festival file is approaching. Today, the editor will continue to share professional knowledge for everyone. The ALPD? miniaturized light source is taken as an example to share with you the projector's off-light situation and corresponding policies for your reference.

1 display error code: E22507

01 Failure phenomenon and cause analysis:

The light goes out in the middle of the startup process, and the LCD screen displays error code E22507, which is caused by the low speed of the pump. It may be due to the following specific reasons:

The water-cooled circulation system is not smooth and the pump is idling

Water cooling control board reads abnormal speed of pump

Pump failure

02Troubleshooting:

Make sure that the water inlet and outlet pipes of the water cooling system are connected properly, and check whether the water pipes are bent or bent

Plug and unplug the water-cooled control board to ensure that the water-cooled control board and the water-cooled backplane are in place.

If the above operations do not take effect, please contact a professional engineer.

2 display error code: E23911


01 Failure phenomenon and cause analysis:

The light goes out halfway during the startup process, and the LCD screen displays an error code E23911, indicating that the system IO port detection is not connected, it may be due to the following specific reasons:

Communication abnormality between water cooling control board and main board

Communication between the water-cooled control board and the water-cooled control backplane is abnormal

02Troubleshooting:

Check whether the communication cable between the water-cooled control board and the main board is connected normally. Replug or replace the communication cable.

Plug and unplug the water-cooled control board to ensure that the water-cooled control board and the water-cooled backplane are in place.

3 Error code displayed: E31807, E31907

(Alarm W31906 and W31907 are handled in the same way)

01 Failure phenomenon and cause analysis:

If the light goes out halfway during the light source startup process, the LCD screen displays error codes E31807 (predicting that the laser current detection of the power module is too low) and E31907 (predicting that the single laser current detection of the power module is too low), it may be due to the following specific reasons:

Poor contact of laser power supply line

electricity failure

02Troubleshooting:

Clean and unplug the laser power cable of the power supply in case of power failure to eliminate the cause of dirt and poor contact

Plug-in laser power adapter board wiring

If the above operations do not take effect, please contact a professional engineer.


4 display error code: E33737

01 Failure phenomenon and cause analysis:

The laser light source cannot be turned on or turned off during operation. If the laser alarm is E33737, it may be due to the following specific reasons:

Power supply and main control communication abnormal (usually appear on some projection platform models)

Dual power solution, error is divided into 3 types (only applicable to dual power laser projection platform)

> Power 1 no tick

> Power 1 no tick

> Power 1 no tick

02Troubleshooting:

Check the communication cable between the power supply and the master

Crossover power supply loop communication board, see the error, the power supply will not change (re-power on)

If the above operations do not take effect, please contact a professional engineer

The above are some of the ways to eliminate the laser projector's light off, which I shared with you today. More content will be shared with you in the next issue.
