Check the LED resistance and put that across the LEDs to test them. Don't directly short them. Most of the time, these LEDs are in series, acting as voltage dividers. Shorting one may put too much voltage across the others, burning them out.
I have 2 bulbs that were dim. I knocked one with a knife, knocking on the yellow LED squares, to get it to jiggle back into full bright. Once I got that one working, then I tried knocking the other one, but while doing so, the first one went back to dim again. Then while trying to get that one bright again, I touched the knife to a dark part and saw a puff of smoke. Now that one is permanently dark without even a bit of bright. The other one lights up very dimly when I put the two sides of a pair of rubber handle, needle-nose pliers to each LED square like these videos always say to do. But _never_ does it cause to light up all the other LEDs when you come upon the one LED that's defective. On many LED squares they all spark to life but very dimly. I don't know what your instructions are good for. I tried putting the two sides of the pliers on each LED of the first bulb and _not one_ lights up. They all stay dark at all times. So now what?? How do I fix my 2 LED bulbs???
Thanks for sharing your video ; This is a "short term" fix / solution only but do remember that each LED draws a certain amount of current from the total available current that's applied to the globe , by bridging the gap of the "stuffed" LED - the remaining LED's will get a slightly higher amount of current through them all & their lives will be shorter than that of having all LED's working but by replacing the missing LED if possible - you'll be able to keep it working properly as intended ; the only question is to where you'll be able to buy these small SMD ( Surface Mount Device ) LED's on their own to replace the "stuffed" LED that caused the issue in the 1st place.
Everything you're saying is absolutely correct, but at least you can get a bit more use out of the bulb before it is rendered useless. Also, the dome on the bulb traps heat and causes the LED's to burn out quicker, and if you leave the dome off and drill holes in the bottom part, it will ventilate the LED's and chips, allowing them to run cooler, and giving them longer life. Manufacturers are missing a sure bet by not making a domeless LED light bulb with LED's which you could plug in and unplug as easily as you plug in and unplug an electrical cord, perhaps with the help of a simple chip puller/seater, then selling individual LED's rather than entire bulbs. I suppose that would cut down on their profit margin a bit though, and since the whole thing is about profit, they'll probably continue to prefer built-in life limits rather rather than make something which is as good as possible. There's also the question of whether consumers would buy something which looked so radically different from what they've become accustomed to using.
@@Chompchompyerded Well said! , I believe that it's all about "Marketing" too ; if every product is "made to last' - they lose out on their profits & if it only lasts a short while - then it means that we "have to" keep on buying their items ensuring that they keep on making them as a "Flawed" product.
@owlhuman I did this to one of my burned out bulbs a couple of weeks ago. It works fine, but without the diffuser on it, it burns blindingly brightly. It's much cooler, but wow! Don't look directly at it. It's brighter than the mid-day sun on Mercury.

@@vibhordublish9914 I thought about the same thing. Measure the resistance of a good LED and go buy a resistor closest to that value. Then solder it back into the removed LED. The current should stay about the same. It is not going to be as bright. I believe it is a series circuit. Many people in the comment section recommend leaving it open. This makes sense because of heat will be dispersed easier.
Bermanfaat infonya. Seumpama sulit tidur bca halus "Allahulaaaaailla haillahuwaalhayyul qoyyumlatakhudu husinatuwwalaanaum" berulang2 sampai tertidur, tetanggaku tidak mau bca awal ayat Kursi itu saat sulit tidur saat meninggalnya tidak baik. Bcanya halus tapi jngan terlalu halus. Doa itu untuk pmbca yg islam.
Bertahana hanya beberapa jam😂,kalau LED yg lama dibuang,lgsg di jumper seperti itu,Jadi led nya berkurang dan tegangan berlebihan.. maka apa yg terjadi!.. usia LED yg lain tidak bertahan lama 🤣🤣🤣.. akhirnya semua led akan terbakar 😂
I tried to check the damaged smd exactly the same way u did in the video and the bulb gave light for a second but then other smds burned immediately ... Why???
@@Pc.Farmer Thank you for your attention .... Agree with you , but he just used a piece of wire (red) for the checking and didn't mention anything about redistors.
Though a short cut a very unscientific and unprofessional way of repair. With such repair the bulb is definitely get damaged in few days The damaged led should either be replaced with new or with equivalent resistance
I wish all LED lights were obsolete. They ruin the night sky (you cannot even see stars in a city anymore), they blind you when driving from oncoming cars and they even change the colour of items, so you're unsure of the correct colour (for people who rely on colour design). I curse whoever invented LEDs. They are just awful.
