If the tower clock fails, it is indeed a very difficult problem, and today the tower clock manufacturer will actually introduce the common problems of the tower clock. I hope I can help you.
1. The crystal oscillator circuit of the tower clock and the resonant capacitor are destroyed, and the voltage of the two pins of the crystal oscillator circuit is abnormal after the destruction, the output of the clock chip is abnormal, and when there is a voltage without wave mode, the whole motherboard has no clock and no calibration. When the frequency is offset, there will be no CPU, can not install the system, can not enter the system, the blue screen of death during operation, the CPU frequency identification is not correct, and even the old CPU will work normally and the new CPU will not work.
2, the probability of tower clock circuit failure on the motherboard is not high, and sometimes it is not the destruction of components. Air welding, too heavy oxide layer will lead to abnormal work of the clock circuit, welding method to deal with the clock circuit fault is the way we often choose, power supply components, crystal circuit failure rate is relatively high.
3, the clock goes or goes slowly, may be because of the geographical location of the clock; Pendulum adjusting nut loose; When the needle tube and hour hand match loose, there is a problem of slipping needle; The escapement fork teeth are too shallow or touch the escapement wheel teeth, when this kind of situation occurs, we can remove the nuts, pad a rubber or wood, the slot is parallel to the operating table, and then tap with a hand hammer to make it slightly deformed, suitable, and can also be clamped with pliers. Use the pliers to look down the four spring claws, raise the total height, the four heights are required to be consistent, the friction torque is 0.2-0.6N.m, and the rotation should be stable.
The above is the analysis and introduction of the common problems of the tower clock manufacturers, thank you for your attention!
