How to fix the led light if it doesn't work?

If the led lamp doesn't work, it can be repaired by replacing a new lamp strip and a new driving power supply.

If the strip in the led lamp is aged or damaged, you can only replace the strip in the lamp tube without replacing the lamp shell. You can buy a suitable lamp and take it back. First cut off the power supply, then use a screwdriver to remove the screws, remove the broken light strip and replace it with a new one.

Sometimes it's not because the led light is broken, but because there is something wrong with its driving power supply. To replace the power driver of the led lamp, you need to buy the same type of driving power first, then remove the left and right wires and replace the driver, and finally try to see if it can light up normally. If it lights normally, it means that the maintenance is completed and the lampshade can be installed.

Be sure to find out the real reason before repairing the led lamp. Otherwise, the purpose of maintenance cannot be achieved, and time is wasted in a hurry. So first of all, we must find out the real cause of bulb damage, so as to get twice the result with half the effort.
