How to test if LED chip is faulty?

To test the Failed chip, You simply plug in your LED panel and short each individual LED chip. Shorting a Failed LED chip will cause board to start glowing sans the faulty chip. Other Safer method is to use a small 3v Power source (Like 2x AA batteries) and hook up Thin probles to the output.

What happens if you short out an LED panel?

If all faulty chips have been shorted out, rest of the panel should glow right up. Usually shorting 2~3 chips over the entire count of LED chips will have no detrimental effect. Because the LED panel is wired in series, it will keep the current same across all chips. Your Panel wattage will decrease slightly.

What voltage do LED chips have?

Now the way these LED chips are laid out are usually very simple. All the LEDs have forward voltage of about 3.2V and are connected in Series. Chip boad failures means its just one or two LEDs have failed, causing entire board to not glow.

Step 1: WARNING: Mains Electricity!

This project involves dealing with mains voltage! Extreme care should be taken if you want to attempt a similar repair. If mishandled, mains electricity can kill you!

Step 2: Diagnose the Problem

I had this LED light mounted in my home and it recently stopped working after a problem I had with a loose ground wire. I already replaced it with a new one but I wanted to see if I can repair this one and use it in my workshop.

Step 3: Try Your Fix

After I removed the leads from the old resistor I’ve inserted the new pair through the same holes and without further inspection I was eager to try the lamp out. I connected it with some jump leads to a mains plug, making sure to isolate all of the jump wires connections for safety.

Step 4: Diagnose and Fix - Again!

I removed the light from the mains connection and continued with further inspection. What caught my attention is this smoothing capacitor that was across the input on the bridge rectifier as it had some discoloration. I removed it from the board and sure enough, the capacitor had a crack on one of its sides.

Step 5: Success!

Sure enough, I had a success. The light started working and even though it looks flickery on camera it produces a nice light in person. I then set to isolate the driver board and proceeded with assembling it back to its case.
