Anonymous users2024-01-24It's the hardest thing to check when it's on or not.
Problem analysis: 1. In this case, the lights in the kitchen and living room are parallel circuits, and there are places with poor contact on their common circuit (in front of the branch).
2. Theoretically, there will be no joints in the line in the dark pipe. The connector is generally made at the junction box (switch box) and the connection of the lamp port, because the two houses have the same problem, the first consideration is that there is a virtual connection in the junction box at the junction of the circuit demarcation.
Solution: 1. There is a multimeter, find the branch of the circuit, measure the voltage, continue for a period of time, if the problem is confirmed, then power off and re-make the joint and do insulation (electrical tape).
2. There is no multimeter, power off, re-do the cable connector and insulate directly at the circuit branch.
3. Power on and turn on the light for testing. Finish.

Anonymous users2024-01-23It must be a problem with the switch, it should be a bad contact with the switch, try to change the switch.
Just measure whether the power supply line of the lamp is 220V. >>>More
Summary. Hello dear. Turn off the power switch, check whether the LED tube is black and dark, if so, it may be that the LED has been broken, you can replace it with a new one, if not, take a look at the interface, tighten the switch by hand and try, the problem solving instructions are that the interface is loose and the contact is poor. >>>More
Most of the metal pieces in the switch are not in good contact, you can change the switch.
If the contact is not good, tighten the bulb tightly and look at it, and if it doesn't work, change the bulb.
It won't be a problem with the TV, you can turn off the gate knife that is plugged in the control ground, turn on the lights, try it to know whose problem it is, it is estimated that it is a problem with the circuit during the decoration.
