The balance car was energized and no response was maintained.The following are some possible maintenance steps to solve the problem of the hovercar not responding to electricity:
1. ** Checking the battery **
- The battery level was measured. If the battery level was zero, it might be uncharged or the battery was faulty. If the battery is recharged, try charging it with the original charger for a while before checking if it can be powered on.
- For a portable battery, remove the battery and check if there are any signs of ignition or corrosion at the contact between the battery and the host. If there are traces of ignition, it may be caused by a short circuit. It is necessary to further investigate the host circuit. If there is corrosion, you can use a clean cloth to wipe the contacts, remove the corrosion, and then re-install the battery before trying again.
2. ** Checking the controller **
- Similar to the Xiaomi 9 scooter, if there was no response after the upgrade, it might be a controller failure. In this case, professional maintenance personnel may need to disassemble the panel to check the controller and replace the controller if necessary. However, the controller was more expensive. For example, the controller of the Xiaomi No. 9 hovercar might cost more than 300 yuan.
3. ** Checking circuit components **
- If the balance car was flooded or damp, like the elephant balance car being washed by a high-pressure water gun, it might be a short circuit. He could check if there were any water stains on the circuit board and clean them up if there were. At the same time, measure whether the power supply end of the host is short-circuited, and check whether the pins of the components such as the field effect tube are short-circuited. If there are short-circuited components, you can buy the corresponding components for replacement.
4. ** Check other parts **
- Check whether the external parts such as the handle of the balance car are damaged and affect the internal circuit connection. If the handle is broken, it may affect the internal circuit. If the circuit is broken or the connection is poor, it needs to be repaired or reconnected.

Ox induction cooker is energized, no responseThe Ox Induction Cooker's lack of response may be caused by a variety of reasons. The following are some possible fault points and maintenance methods:
##1. Power Circuit
1. ** Low voltage power circuit malfunction **
- Check whether the AC220V input is normal. If there is no AC 220V input voltage, it may be a problem with the power cord or socket. You can unplug the induction cooker from the power socket and plug it into other devices to confirm that the socket is working properly. If the socket is normal, check if the power cord is damaged.
- If the AC220V input was normal, the low-voltage power supply circuit would convert the AC220V into low-voltage direct current voltage circuits such as DC +5V, DC +12V, DC +24V, etc. through components such as a transformer, and supply power to the control circuit board and the operation display circuit board. The focus was on detecting the transformer, voltage stabilizing circuit, and related vulnerable components that generate the direct current voltage.
2. ** High-voltage power circuit malfunction **
- The AC 220V input voltage was converted into a circuit with a voltage of 300V through a bridge rectify stack, choke coil, and smooth-filtering filter. It was specially used to supply power to the power output circuit. If the voltage of DC300V cannot be detected, then the focus should be on the bridge rectify stack and the smooth filter.
##2. Fuse and related short-circuit-prone parts
1. Fuse Burned Condition
- If the fuse was blown, it meant that there was a short-circuit on the main board, which led to the fuse being blown. The power tube and the bridge stack were the easiest to short-circuit. You can first check whether the power tube (such as the three-pin power tube) and the bridge stack (the four-pin component) are short-circuited. If the power tube was short-circuited, 001 appeared on the digital meter to prove that the 1 - 3 pins were short-circuited (any pin that was connected proved to be damaged); measure whether the four pins of the rectify bridge stack were short-circuited. If one of the pins was short-circuited, it was bad.
- The induction cooker must be checked for the rectify bridge, the power tube IGBT, the resonant capacity, the filter capacity, the anti-interference capacity, and the 18-volts voltage regulator and its drive circuit. Most of the induction cooker drive circuits used 8050 and 8550 triode; at the same time, it was necessary to check whether the 18-voltage zener junction connected to the power tube 1 and 3 was burnt out. If the 18-voltage zener junction was broken down abnormally, the power tube would be burnt out.
- If the fuse was blown open, the main circuit's IGBCs and the rectify bridge would definitely have been broken down. He also had to check if the 5 microFarad filter and 0.33uF resonance were bulged.
##3. Problem with the keyboard
1. The welding point of the button is corroded by water
- If there was no problem with the power-related parts, it might be a malfunction of the button panel. For example, there were traces of corrosion on the buttons, which might cause no response when the phone was turned on. If there was a universal meter, it could be used to test whether the welding spot was connected. If there was no universal meter, after the power was turned on, it could be directly connected to the switch button with a short wire to see if it could be activated.(The voltage on the button board was 5V, but the voltage on the main board was 220V. Pay attention to safety during the power-on test.) If it is determined that it is a button problem, in the absence of a suitable button switch, you can consider removing other function buttons (such as the timer button) and installing them at the switch button for emergency repair.
During the maintenance process, if it involved the operation of the internal circuit of the induction cooker, due to the high voltage inside the induction cooker, it was necessary to have a certain basic knowledge of electrical engineering and pay attention to safety.

The baler is energized, but the voltage meter does not respond. What is the cause?This isn't related to online novels. If the baler was powered on but the voltage meter did not respond, it might be that the voltage meter was broken, or there was a problem with the circuit connecting the voltage meter, such as a broken circuit, poor contact, or the fuse in the circuit was blown. There might also be other faults inside the baler that caused the voltage meter to not receive the correct voltage signal.
