Common Faults While Using Home Theater Projector

Users who often use projectors can encounter some problems. For example, when the projector is connected to the power supply, it can't be turned on, or the laptop screen is turned on but the projector screen is not turned on. Are these situations projector failure or misoperation in use? Today, we will summarize these common problems and give solutions. If there are problems described below, you will know how to solve them.

1.Why the projector doesn't respond when the power is on?
Answer: since there is no response after the projector is powered on, it is likely that there is a problem in the power supply part of the projector. But is there something wrong with the internal or external power supply of the projector? For this reason, you should first check whether the external power specification of the projector is the same as the standard required by the projector. For example, if the external power socket is not grounded or the power connection cable used by the projector is not equipped with the projector, it may cause the power input of the projector to be abnormal; Once it is confirmed that the external power supply is normal, you can conclude that the internal power supply circuit of the projector is damaged. At this time, you have to replace the internal power supply of the projector.

2. Why is the projector turned off suddenly at work
Answer: if the projector is shut down suddenly in the process of operation, there are two main reasons. One is that the user may accidentally cut off the power supply of the projector during operation, so you should first check whether the projector is shut down due to human factors. After eliminating this situation, it means that there is a problem with the projector itself, and it is probably caused by thermal protection. In order to prolong the service life of projectors, there are many high-grade projectors, often using a self thermal protection function: when there is too much heat generated inside the projector, the working state of the projector will automatically work in this protection state, and the projector will automatically be turned off, and in this state, the projector will not respond to any external input control; So when this happens, you don't need to worry about the sudden failure of the projector. You just need to be turned on the projector according to the normal power on sequence about half an hour after the projector automatically is turned off, so that the projector can return to normal operation.

4. Why can't it project the entire image content?
A: it can't project the whole image content, which indicates that there is a problem with the display resolution of the projector. At this time, you can readjust the resolution parameters of the computer and the projector to make their sizes match each other.

5. Why does projection produce distortion?
Answer: the content projected by the projector is distorted. It is likely that the position between the projector and the projection screen is not aligned. To eliminate this distortion, you can adjust the lifting foot seat of the projector, or adjust the position height of the projection screen to ensure that the image projected on the screen is rectangular.
