(Ultra-thin integrated lifter, paperless conference system) The projector in the intelligent conference system does not light up
Solution: There are usually two representations of the projector that are not lit: A. The projector is not powered; B. The power is not projected.
Step by step check as follows:
Step 1: Determine whether the projector (ultra-thin integrated lifter, paperless conference system) is working properly.
Q1: Is the projector's power switch turned on and the indicator light is on?
The indicator does not light after power-on, indicating a problem with the projector. Under normal circumstances, the hard switching power supply of the user's projector is long open, and the power indicator light is long. Among them, yellow light: waiting; green light: normal; red light: power up
Q2: Is the LAMP lamp and TEMP lamp long or blinking? (showing red)
A red light on the LAMP indicator indicates that the projector lamp is broken, reminding the user to replace the lamp.
The red light on the TEMP indicator indicates that the projector is in an error state and cannot be projected. The projector is in self-protection or the hardware is bad.
Q3: Let the user connect the computer directly to the projector. Does the projector project? Does the projector's port setting for receiving signals match? (such as whether it is a VGA receiving port)
If the projector is not projected after connecting the projector directly, if the projector has a normal projection, it indicates that there is a problem with other related devices or cables connected to the projector.
Step 2: If it is judged that the projector is working properly, check other devices connected to the projector: table plug, matrix, VGA splitter and the connection line between them.
Q4: Is the matrix turned on? (Ultra-thin integrated lifter, paperless conference system)
When the VGAS matrix is ​​turned off, all VGA signals will not be switched to the projector. Look at the power supply board for power. After power-on, the matrix does not light, indicating that there is a problem with the matrix.
Q5: Is the desk plugged in?
The power indicator on the desk is not lit, indicating that the desk plug is not powered and cannot transmit signals. Look at the power supply board for power. After power-on, the desk plug indicator does not light, indicating that there is a problem with the desk.
Q6: Is the VGA splitter powered? The power indicator of the splitter is not lit, indicating that it is not working, and the signal cannot be transmitted. The power supply board connected to this is powered. If the power indicator is off after power-on, there is a problem with the distributor.
If the above devices are powered up normally, it is necessary to judge whether the matrix, the table plug, the distributor and the connection have quality problems. At this time, maintenance personnel need to go to the door for maintenance. (Ultra-thin integrated lifter, paperless conference system)
