- Inappropriate transformer for low-voltage lights
- Inappropriate dimmer
- Defective power supply unit in the lamp
- Fluctuations in the power grid
Can LED lamps be repaired?
A great benefit to LED bulbs is you can repair almost everything. Premature burnouts can be caused by poor component quality, LED overheating, and voltage jumps. The good news is that you don't have to have a lot of experience to handle the repair and the cost is significantly less than the price of a new bulb.

What's inside a LED light bulb?
It's called solid-state lighting because unlike incandescent and fluorescent lighting technologies, there are no gases involved in LEDs. Instead, energy is passed through a semiconductor (usually a solid chemical element or compound that can conduct electricity), lighting up the LED light bulb.
How can you tell if a LED bulb is burnt out?
Wait for the LED to light up. If your LED does not light up, it may be burnt out or defective. If your LED doesn't light up, try testing other LED lights right after it. If they light up, you can be sure that the first LED doesn't work.
Why do LED lights fail?
There are two different metals inside the LED light fixture - the socket contact and the LED lead. When exposed to water (and even oxygen, from which the air we breathe consists), these materials can undergo a chemical reaction that causes corrosion and finally failure of the light bulb. Luckily it's easy to enhance the waterproof characteristics of an outdoor lighting by using some dielectric grease. It will stop the humidity and air from getting into the LED light and consequently prevent the corrosion.
What happens if one bulb is not working?
If the one bulb is not working the whole string fails, so the failed light usually cannot be detected. Thus you'll need to pull out each bulb and successively insert a new one in its place until you find the failed one. Read the user's manual before doing this. Sometimes you may detect the stuck caps.
Can you replace a dimmer switch with a CFL?
However if you have an old dimmer switch, it may not always be compatible with the contemporary LEDs. Try to replace a couple of LED light bulbs with the CFL lights. This will correct load problems and most likely fix the flicker of remaining LEDs. As you can see, most of the problems can be fixed by yourself.
Can water get into LED lights?
In the USA, Canada and most of Europe winter is usually very damp, so the water can get into lighting fixtures. LED outdoor lights are supposed to be sealed, but the assembling is not always perfect. And when water gets into a LED light, it causes corrosion which will obviously ruin the electronics inside. fixing LED lights.
Can you use grease to waterproof outdoor lights?
Luckily it's easy to enhance the waterproof characteristics of an outdoor lighting by using some dielectric grease. It will stop the humidity and air from getting into the LED light and consequently prevent the corrosion.
Can you replace a string light if it fails?

There are two main ways of making string lights - in first case failed bulb will stop the work of the whole string, and in second case the string will still be working but the rest of LED bulbs will be under the higher voltage which may cause additional failures.
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.
