Fix Led Bulb
- Opening Bulb. Those bulbs are easily opened using a screwdriver around the joint , pieces are made of some kind of plastic , so no worry about break ...
- Testing Leds. Leds are diodes that emit light , then being a diode means that current goes just in one direction , not the opposite .
- Smash the Black Sheep. Smash burnt led with flat nose plier .
- Soldering. Remaining place left by led are metal base on PCB . ...
- Finish. As led are very bright i could not show the result , i mean other leds working despite that there is one less.

Can LED light bulbs be repaired?
Traditional incandescent light bulbs cannot be repaired at all, while in LED bulbs you can repair almost everything. You just need to find the malfunction, make some repair and prolong your light bulb lifetime. If you are familiar with repair operations you can even find all necessary tools at home; all you need is to find some time for that.
How do you fix LED lights that don't work?
You can do this easily by powering up your circuit and seeing which bulbs don't light. Generally, replacing faulty bulbs will solve issues with LED circuits and fix broken LED lights. Depending on your circuit, you will need to connect the battery or plug it in.
Why won't my LED light bulb turn on?
If the entire circuit isn't lighting up, there could be a problem with your power source. Remove the broken LEDs. You may need a soldering iron to do this, depending on how the LEDs are connected to the wire.
How do you fix a broken led board?
The board may be fixed using a PCB holder (we then have both hands free). If possible, heat it up from below with a hot air gun. The temperature shouldn’t be high, about 100 ÷ 150°C, in order not to damage the working diodes. It is convenient to take off the old LED with hot tweezers that heat up both outputs at the same time.

Replace the LEDs with lights of similar voltage. ... Step 4: Connect Replacement Lamps. ... Step 5: Finish the Fix for Your LED Lights.
Can LED light bulbs 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 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.
How do you troubleshoot an LED bulb?
You should first check whether the fuse for this circuit has tripped. If the ceiling light has already worked before, the lamp may be broken. Then you should check whether the light sources are replaceable. In this case you can replace the bulb with a new LED bulb with a suitable socket.

How can you tell if an LED bulb 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.
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!

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.
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.
What is a LED Bulb?
A LED light bulb, sometimes referred to as a LED lamp, is an electronic lighting component that uses light-emitting diodes (hence the name LEDs).
How to Construct the LED Bulb Circuit?
First, you will conduct this DIY using a power source directly from the main supply at 230V Alternating Current. Therefore, you have to take care.
