Solutions to the problem that the hard disk video recorder cannot be started
The machine cannot be started
. The input power is not available Equipment failure caused by errors and incorrect power supply generally have the following possibilities.
The power supply line or supply voltage is incorrect.
The power is not enough (or the wire diameter of a certain power supply line is not enough, the voltage drop is too large, etc.).
The transmission line of the system has short circuit, open circuit, instantaneous overvoltage, etc. In particular, equipment damage often occurs due to power supply errors or instantaneous overvoltage. Therefore, it is necessary to use a multimeter to measure before supplying power. But sometimes, the live wire and neutral wire of the power supply are installed backwards during project installation, making it difficult to check. The engineering contractor needs to be reminded to pay attention.
. Hard drive is damaged or hard drive cable problem
. If the machine's power supply is faulty, you can try replacing it or short-circuit the green and black wires in the power supply and the motherboard's terminal block, and use a multimeter to measure the power output< br/> .Front panel problem: Short-circuit the green and black wires in the terminals between the power supply and the motherboard, and start the hard disk video recorder. If it runs normally, it can be basically concluded that the problem is with the front panel or the connection line with the front panel. You can Check whether the connection between the front panel and the motherboard is loose or whether the microcontroller chip on the front panel is loose
. If it still cannot be started, it may be a hardware failure of the machine. You can feed back the serial port information of the machine startup to the company's technical support department or Send the machine back to the company for repair.
