Can an integrated LED light bulb be replaced?
Unlike traditional bulbs that can easily be detached from their fixtures, integrated LED bulbs are built into multiple electrical circuit boards. This means that it cannot easily be replaced if a bulb blows, especially not by the average person. Instead, the whole integrated fixture must be replaced.

Can you repair LED bulbs?
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 causes an LED light to stop working?
Reasons often include a faulty power supply, loose connections, a faulty circuit design, or even damage due to water ingress caused by rain. Whatever the reason is for your LED lights not working and whatever the tell-tale signs are, there's usually a solution to the issue.
What causes LED to burn out?
The most common reasons for LED blowing out are high voltage, bad contacts, use of incompatible dimmer switch, or recessed lighting. Other causes include overheating due to not using the right fixtures, or simply a bad batch of lightbulbs!
Why are half of my LED lights not working?
But the answer is simply that one colour of the RGB/W LEDs is not working within that section and needs replacing. This can be caused by static-electricity damage, or bending and twisting the strip too much, or being trod on, damaged in transit, a cheap poor-quality strip, or dry solder joints.
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.

What happens if your LED lights won't turn on?
If your LED light strips will not turn on at all, it is likely a poor pin connection. This is akin to charging your cell phone or plugging anything into an outlet. If the metal prongs are not securely connected inside the outlet, you will not get the desired result.
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.
How do you tell if an LED light is burned out?

How do you tell if a LED light is blown?
It's an LED. Easiest way to see if it is damaged is to connect it to a battery and see if it lights up. The difficulty is that you can't disassemble the the white plastic unit, so if the LED does not light, the connection wires, resistor or LED itself may be damaged.
How do you know if LED light is busted?
When you are testing your LED, take notice of its brightness. If you are already in a lit room, then shade the LED with your hands. A lower efficiency LED will grow dimly, or may just gleam faintly, whereas a higher efficiency LED will glow clearly.
How do you reset LED lights?
To begin with, make sure that your LED light is plugged into an outlet. Next, press and hold the button on top of the power cord for at least 10 seconds. After this time has elapsed, release the button and wait approximately one minute for it to turn off automatically before unplugging it from its outlet.
How does a light emitting diode work?
Let’s use a popular SMD LED in the 5730 housing to illustrate the LED operation.
LED bulb main parts
Dissipator. It reduces the irregularity of a light flow and extra lightness of some emitting elements. It also ensures lighting under a certain angle (for household lamps it should be wider).
Bulb operation and troubleshooting
The bulb operation principle is rather simple: AC current is provided from electricity line to the driver through contact wires, where it becomes DC and runs through LEDs that transforms it into light. The heat is withdrawn using a board containing LEDs and a heatsink.
LED replacement
Now when you have found a faulty diode, it has to be changed. It is soldered to the board. Overheating hazards are critical in diode operation. Keep in mind that soldering recommendations are included in diode technical specifications.
Other failures
If all the diodes turned out to be working during the test, you should check the bulb driver and search for other damage, as well as check the conductors and contacts for discontinuity.
Step 1: Remove the Top Cover
Remove the top cover (diffuser) then desolder two wires of ac mains from the board.
Step 3: Check All Led
Set your multimeter to continuity mode then place your positive lead to positive side of the led and negative lead to negative side of the led. Mark the faulty and led.
Step 7: Replace the Capacitor
In the backside you can see two capacitors one is electrolytic and another one is polyester capacitor. Replace that 47mfd/63v electrolytic capacitor with new one.
