LED light repair || problem: The circuit was burnt.

How are you all? I hope everyone is well and healthy by the grace of God. Today I will share with you an LED light repair.

A man in our area called me and gave me an LED light and said that the light went out at night due to a loud noise and is no longer working. Then he asked me how much it would cost to fix it. Then I said it might cost 30 taka to fix it, and if the LED light and the circuit are damaged together, it would cost 50 taka. And by liking it, I checked it directly, and I saw that its LEDs were good; I suspected that the circuit was bad.

How I fixed this light, or step by step, is shown here.

Step -01

First I took the LED light and sat it on my work table, then I took a two-pin plug holder with a wire and took a digital multimeter to check the output. Then from the light, I removed the white plastic cover on the top, and you can see that all the LEDs are beautiful here; no LED is burnt.

Step -02

Then I turned on my digital multimeter and selected DC 1000 voltage because this circuit outputs DC 220 volts to 240 volts. And my multimeter's point was 200, then 1000. Then I checked the line with 220 volts input voltage in the folder, and the multimeter did not show any output here. This means that my circuit is giving output and the circuit is damaged.

Step -03

Then I have to turn the light over and remove two pins from the pin holder cap from the back side. Through this pin, 220 volts is input into the circuit. Then I took out the old circuit from the body cover of the light. You can see that I zoomed in here and saw that an IC was burnt and the capacitor was damaged a lot.

Step -04

Then I took a new circuit to repair the light. And these circuits are not very expensive because they are the cheapest circuits in the market, and these lights are very cheap. My Bangladeshi market price is 10 to 12 taka. Then I soldered the positive and negative lines of the LED with the output voltage of the new circuit and connected them nicely, as you can see in the picture.

Step -05

Then I fitted the light and gave it 220 volts input voltage, and you can see the light is working very well, and I kept the old circuit in my hand. By changing this circuit and spending 10 to 12 taka, my light became operational again, and it will be able to serve for more than three to six months again. And with my repair, I took a picture and completed my work.
