Fixing broken LED light strips, LED Tube lights, or LED light bulb that wont turn on could be very easy! Don't throw them away!

Following is step by step guide on how to fix or repaire faulty LED Lights.

Step 1—Disassemble the bulb by removing the dissipator housing with a small screwdriver.

Step 2—Locate the burned out LED by looking for a black spot or burn marks.

Step 3—If there is no visible damage, use a multimeter to test the diode function. Touch the anode with the red probe and the cathode with the black probe to locate the diode that doesn't light up.
