How to repair a New Year's garland

Very troublesome, especially if the hands do not grow from there. The garland can now be purchased for mere pennies and less headaches, and you don’t need to strain before the holidays ... You still have time)))) Good luck!)))))

I want to tell you, as a person with an energy education, and having more than 10 years of experience in an energy enterprise, not a single electrician will sort out a faulty garland at home !!! Imagine how long it will take !!! I have a garland of 500 bulbs at home, and no matter how you look for it the place of damage - it will go to repair and everything about everything for at least 2 hours, or even more !!! I also want to note that any repair in electrical networks by an amateur is obviously a huge risk. So I advise everyone to heed the last sentence of the author - "Better buy a new high-quality New Year's garland! In the New Year you need to enter with new things!"

:) You can think of these 2 hours a "certified electrician" will spend on spiritual growth or invent a vaccine for a terrible disease. The direct duty is to poke a tester. And if he is not interested in repairing an electronic device, then he is simply a craftsman without imagination.

Actually, an article on how to repair and not how to buy. Are all energy experts regularly buying garlands of 500 light bulbs? With so much they should burn quite often. And Oleg is right. In vain to poke a tester and work for yourself? And Oleg called such people correctly. God forbid such a husband. Sockets, probably, the wife is repairing or a dumb electrician from the housing office with the formation in 9 classes.

Margarita, as you have noticed, shortening light bulbs is an option, but not the best. If it is not possible to replace the bulb, it is better to put a diode in its place, which will reduce the voltage on the garland and subsequently shorten up to half the bulbs. Which diode? Ask any radio technician for a diode of at least 300V. For example, D226. Their shaft and gift. A good article.

For some reason, the device for searching for hidden wiring is not mentioned (as an option, something homemade from this). Search is accelerated as much as possible.

Now full of LED lights. And the LEDs are connected in parallel.

Parallel to what? )))

Parallel to each other))) A connection in which the current strength of the entire circuit is equal to the sum of the current strengths of separately connected conductors. The voltage is the same everywhere. With a consistent, by the way, the opposite is true.

I wrote it out with ebau - a device for covert wiring of a vsgo for 50 rubles. Found a cliff in the garland very quickly.

Tester, pin, and no rations. You can, of course, buy, but why spend the money? At the enterprise, every penny saves a dollar. You can, of course, solder the wires, but a soldering iron is a relic of the past. The soldering iron is used, your own, and only for the repair of home appliances. And on the tree ... but who will look there, which garland, bought, or repaired. The main thing is that the lights are blinking.

She worked for me, and then stopped a few minutes later. What is it I do not understand. Help, I do not want to spend money.

I bought a garland, and after half an hour two of the four colors stopped burning, how to quickly determine the cause?

Ilya, you can try to open the remote control, which switches the operation modes of the garland. In many garlands, colors work in pairs, that is, two colors are soldered together to one terminal on the board. In your case, the conductors of two colors could come off, which would need to be soldered back to restore the operation of the garland.

You can also immediately check the presence of contact at the end of the garland - in the place where the common conductor connects to all the colors.In this case, there may be no contact of two color lines with a common conductor.

In general, in modern Chinese garlands, very thin wires are literally a hair inside. At the slightest stretch, they break off, and visually this, as a rule, is not visible. That is, in your case, the wire could just stretch out in some place. It also often happens that one of the lamps of the same color burns out and the rest of the lamps do not light up, since a burned out lamp creates a gap in the circuit of one color of the garland. If the burned out lamp is not visible, then it will take a long time to search for it by dialing, the same applies to finding a broken wire, so if the garland is cheap, then there is no point in bothering - it’s easier to buy a new one.

Please tell me: is it possible to repair a separate branch with a red color on an LED garland if all the resistors burn out at first? And somehow it’s not comme il faut - everything burns except for this color.

Denis K, I, too, have been working as an electrician for a long time, and I also took it today and threw this bunch of Chinese crap into a landfill, I’ll repair this one-time rubbish, but I’ll spend time, you’ll start to do it, then the plastic cartridge will roll in my hands, then the wires will fall out, the only thing that bit off the block may come in handy. So I agree with you. And if anyone has nothing to do, let them sit and poke.

I have the simplest idea of ​​electrics, I repaired the garland in 5 minutes, looked for a cliff for a minute, heated a soldering iron for 2 minutes. 2 minutes soldered and crimped by heat shrink. Total 5 minutes business. The device is an ordinary Chinese hidden wiring tester. I found a place where that same thin wire came off .. The Chinese, of course, are tin .. such thin wires are used and at the same time 220 go through them! Horror (

I take the pointer device Ts435, I take a crocodile on one probe, and a needle on the second probe. I put on the measurement of resistances and ttyts, tyts, tyts - gopa! And the bulb is worthless. Shorted her - the garland burns! You can twist one light bulb, a maximum of two. Further it is impossible because the garland will no longer be at 220 volts, but somewhat lower and will quickly burn out.

Evgeny Anatolevich,
The wires are thin and 220 through them ... But then the current is small along them. Fully correspond to the wire load. But of course about the mechanical strength, yes. They are too weak.

That's right, the wires (wires) are thin, and the insulation is several times thicker than the wires. On the one hand - well, they hold 220V. And on the other hand - it is very difficult to check such wires with a needle - you can’t get into the vein. The fastest and safest way is to find a break using a hidden wiring detector. The only thing that in modern garlands are flasher controllers and at the same time several branches are started up. So, while searching for a cliff, the remaining branches must be turned off so as not to interfere. And as for the parallel connection of LEDs, this is not so. In LED garlands, everything is the same as in conventional with incandescent lamps - in series.

You know, the fact that the garland is connected in parallel made me laugh.

Agree with you. The penny is so graduate. They will buy diplomas and antlers on antlers.
