When a newly installed LCD screen lifter or an LCD screen lifter that has been used for a period of time fails, you need to understand the fault before you can operate it when you have to repair it yourself, otherwise it will damage the LCD screen lifter. The following is Maintenance and elimination of common faults:
If the LCD lifter does not respond, nothing moves:
1. Check whether the power supply is plugged in, whether the power cord is properly connected, whether the voltage is normal, if it is not connected, then fix it; if there is no power, check whether the power supply line is normal.
2. If there is no problem with the voltage of the power supply line, you need to check the button connection, check whether the motor connection line is off, and then check whether the fuse is blown, and whether the travel switch wiring of the upper terminal and the lower terminal is off.
3. When the lifting frame is at the upper terminal and the upper terminal travel switch is pressed, the lifting frame cannot go up; when the lifting frame is at the lower terminal, the lower terminal travel switch is pressed and the lifting frame cannot go down. This is a normal phenomenon. Only need to manually press the switch.
4. If none of the above is the case, pressing the up and down buttons will not work, but there is a weak vibration sound. At this time, you have to check whether the capacitor is broken or short-circuited, and then check whether the connection is broken And fall off. When the motor heats up very seriously, it is necessary to cut off the power immediately to prevent the motor from being burned out.
If the LCD screen lifter can't move up or down, but loud noise is emitted from the cabinet:
1. Check whether the transmission chain is disconnected or broken;
2. Check whether the meshing between the aluminum guide rail and the sprocket is misaligned;
3. Check whether the restraint screws between the shaft and the sprocket are loose, so that the shaft cannot rotate with the sprocket, causing the four guide rails to run out of sync;
Hope our introduction today can help you all.
