After installing a projector, projector users will choose to match a projector screen, especially those that use LCD projectors. There are many types of projection screens, including hard screens with light resistance, portable stand screens, and floor pull screens, but many users Installed are electric projection screens.
electric projector screen
The electric projection screen has a built-in electric motor, which can control the lifting of the projection screen through remote control, and the height can be adjusted freely ; most of the materials are plastic fiber fabrics ; most of the homes use a nearly rectangular 16: 9 ratio, commercial Use a 4: 3 ratio close to square.
The reason why the electric projection screen cannot be raised and lowered
1. Due to the foreign objects in the curtain or in the curtain storage box , the electric curtain is stuck when lifting.
2. The failure of the remote control may be due to the failure of the internal circuit board of the remote control, or the battery in the remote control is dead .
3. The screen cannot be raised or lowered due to the failure of the motor in the electric curtain, or the motor is not powered, or the motor is burned . Third, the electric projection screen can not be raised and lowered solution 1. Before lifting the screen, check the screen surface and the storage box for foreign objects , and then confirm that there is no foreign object before lifting operation. 2. If the remote control fails, you can operate it after replacing the battery . If the battery replacement still fails, the internal buttons or circuit board may be faulty . After the investigation, replace it .
3. Motor failure requires investigation, prior to the motor circuit for investigation , after confirming normal circuit again checks the motor if the normal rotation, the circuit elements can replace problem, manufacturers of motor problems require replacement.
The above is the reason why the electric projector screen cannot be raised and lowered and its solution. From the above three points, we can conclude that we must not only develop a good habit when using the projector, but also develop a good habit in the use of the projector screen. The projection screen should also be processed and maintained regularly. I hope the above methods can help the projector users.
