    Good explanation. I installed about 100 of these and believed they would be maintenance-free. So I don't replace bulbs as I did many years ago. But now I need to fix the electronics. I would have discarded and replaced a bunch of lights if not for your instruction.

    • @TasteTheCode

      In theory yes, they should be maintenance free but questionable manufacturing leaves many broken just for some extremely cheap parts. It's good that you managed to fix yours.

    Can I just put a resistor connecting across that particular group of LEDs and make it work?

    • @TasteTheCode
      @TasteTheCode  Год назад +1

      The driver chip will try to push a set amount of current through all LEDs so, it is better to just add a wire link. The downside is that there will be a dim spot in the panel, but it will work.

  • @Accumulator1
    @Accumulator1 10 месяцев назад

    Appreciate this video discussion. Maybe you can bypass the bad segment of LEDs by connecting + and - wires to connect the segment before to the segment after the bad one. Then all will burn except just few LEDs with minimal loss of illumination.

    Thanks for the great video.A nice and clear narration of different steps to repair . I have a driver 18 watt, 50-100v dc ,input 230 volts AC has a transformer towards the output side.Is it stepping down the output of bridge rectifier? In one of other videos you had a choke on the output side.

    • @TasteTheCode
      @TasteTheCode  4 месяца назад

      Thanks! Best option is to check the number on the driver IC and check its datasheet. Almost always, there is an example circuit inside and most of the manufacturers, just follow that when making the lamps. If it is a transformer (as you mentioned usually it is just a choke) then it might be separated from mains as a switch mode power supply.

    • @TasteTheCode
      @TasteTheCode  Месяц назад

      The output current is controlled via some resistors on the board but you will need to find a datasheet for the specific IC on your driver. However, I will strongly advice against this. These drivers are already set on their maximum limits from the factory and pushing them even further is just a recipe for disaster! Find the right driver for the light you have!

    I appreciate your videos but there is just one thing that is driving me crazy and by researching the topic for a minute, I ended up learning even more. The subject is the pronunciation of the word "Solder". Myself being born in the USA the word is pronounced "SODDER" whereas in the UK they pronounce it "SOL-DA" (or something to that effect). I also learned that up until the late 1800's the UK pronounced it the same as the USA, until the derogatory term "Sod off" gained popularity. Then someone over there decided that maybe pronouncing the "L" would help separate it from the derogatory term. I get it. Luckily the USA didn't adopt the derogatory phrase into common vernacular, so we kept the original version. Honestly, we have more than enough derogatory terms thank you.

    • @TasteTheCode
      @TasteTheCode  11 месяцев назад

      Yes, each driver is rated for a set amount of power. Trying to draw more than that will damage it. You can test individual LEDs with a multimeter, but only if they are one LED per package. If they are more than you can't.

  • @oskimac
    @oskimac Год назад +4

    Just remove one bad led. By string it by force and bridge the remaining pad w6a blob of solder and you are done. The panel will be running at a diferent voltage (3volt less) but the driver will take care of that.

    • @TasteTheCode
      @TasteTheCode  Год назад +7

      Yes, I'm aware of that and I've done this in the past with regular light bulbs. The problem here is that there are 5 LEDs in the string that don't light up and that will make a visible dark area on the panel that I don't think will look good.

    Great video! In my case the capacitors looks right, and the values are the expected (measured on the PCB), but the light blink regularly (light half a second off, half a second on; not flickering, as almost all YT videos show). Is this case the same symptom?

    • @TasteTheCode

    @FarizMammadov-qw8rc 11 месяцев назад

    Hello, I have a led light that is controlled by a remote control. I ordered this from a distance and it seems to have been damaged in transit.
    After turning on the light, when I press with my hand where the drivers are located, the light changes color. (for example, if the white LEDs are on, they turn purple) Sometimes it recognizes the remote control and sometimes it doesn't.
    Which element do you think is damaged?

    • @TasteTheCode
      @TasteTheCode  11 месяцев назад

      Sounds like a bad connection or cracked PCB. You can try to inspect the PCB for damage or try to reflow some of the ICs.

  • @oskimac

    I would leave the legs of the first capacitor as long as possible. And not bent it over the board... Keep it as far as you can. To avoid the heat from the chip affecting it on the future

    • @TasteTheCode
      @TasteTheCode  Год назад +2

      It is not the chip only as there is a lot of heat from the panel itself and the driver sits on top of it at all times. Having rhe capacitor away will definitely help but I don't think it will be too much of a difference.

    • @TasteTheCode

      Hmmm it will probably work bit you will be pushing that driver to the max all the time and it might burn out. They are usually designed to pish certain current through the LEDs and they work in a certain range rather than a very specific wattage.

    • @TasteTheCode
      @TasteTheCode  Год назад +1

      Yes, and flashing is a common sign that at least one of them is bad. It might be one of the LEDs as well but it is not that likely. They can be tested with a capacitance meter or a multimeter that has capacitance measurement. However, the cost of the capacitors is so low that it is worth changing them all just in case and trying it out. Make sure that the voltage rating is the same or more than what's already installed.

      That is usually explained in the datasheet for the chip where there will be a formula to calculate the resistor required for the target current.

    Guys, if you end up fixing these try installing lager caps and not smaller like in the video. and higher voltage if you can squeeze those in place. Lager size and voltage will give you a longer run. Say you had 25V 1000uF install 35V 1000uf. Cap body size is direct reference to how many hours it's designed to run for

      It is not uncommon to have chips with markings removed from the top so it is difficult to know what the exact chip is. If you can see a number, you can usually find the datasheet that will have its typical circuit in it. Most drivers are just a replica of the typical circuit diagram from the datasheet.

      Output voltage usually depends on the number of LEDs attached. For constant current drivers, it is the current that they regulate so you can have more (up to chip power limit) or less LEDs and it will still work. If everything else is OK on the board, you can either replace the chip if you find a replacement, or ditch the repair entirely as the price of these drivers in not really worth that much hustle.
