    If the multimeter is detected light source is no problem, then to see whether the power supply problem, LED ceiling lamp is commonly adopt the method of external power supply, then directly buy a power supply to replace is ok, some LED lights manufacturer USES the power supply is not good, the power supply is the most easy to a part of the problem.

2. Then take it apart and check all the key parts: the drive or power, the LED lamp bead, and all the broken lamp beads are replaced.
