FAQS
What should I pay attention to when repairing DVDs?
1) Before maintenance, the user shall be carefully asked about the use condition and fault phenomenon of the machine to determine the fault location. Through understanding the situation, we can accurately judge the fault location to avoid detours in maintenance.
2) Understand the characteristics of DVD and its working principle. Understanding its characteristics before maintenance can be a reference for maintenance improvement.
3) Pay attention to keep the maintenance workbench clean, dust-proof and anti-static. If the air environment is bad, too much dust on the surface will affect its disk reading performance, so it is necessary to keep it clean during maintenance.
4) Note whether the working principle of DVD is consistent with the grid voltage. The working voltage of some imported machines in normal channels is 110V/60Hz. If 220V/50Hz voltage is used directly, they will be damaged.
5) Pay attention to personal safety and the safety of maintenance equipment. DVD is mostly powered by switching power supply. The power supply part has 220V AC voltage, and the hot part is live. If you don't pay attention to it during maintenance, you will get an electric shock.
