New Year is coming! You put a Christmas tree and decided to dress it up ... Pull out a forgotten box with New Year's toys and hang an electric garland on fluffy branches. And suddenly, what a trouble, you notice that it does not work. One lamp burned out in a garland, while others continue to glow or, on the contrary, do not light everything. I wonder why? What to do in this case? What to do? Go to the store for a new garland? The option is the simplest, but not always feasible. Do not rush to throw away the old one, as, most likely, it can be repaired. How to repair a Christmas garland? Fortunately, they all have typical designs and are easy to use. Next, we will tell you how to repair a Christmas garland if a light bulb burns out, contact wires come off or the mode does not work.
What should be considered?
The main thing is to know in what sequence in the garland all the bulbs are connected. How can one find a problem place here? In order to find faults in the circuit, an indicator screwdriver can be used. If you do not have one light on, this indicates that in this case a parallel connection is used in the garland circuit. Repairing the malfunction is easy, you just need to replace the light bulb.
Chinese garland
And how to repair the Chinese garland? It differs in that it is non-separable, disposable and has non-removable bulbs. There is a chain of garlands of four colors, flashing alternately. If one color does not work, what to do in this case?
In all likelihood, one section of the bulbs in the circuit burned out. As a rule, it is non-separable and the chain of bulbs is parallel. If one light does not light, do the following: connect the wires around its contacts. Then the current will bypass the bulb without touching it. And your garland will be saved.
LED garland
The design of the LED garland is such that, as a rule, the program burns out, and the diodes themselves remain. And throw a pity ... How to repair a LED garland? If the lamps do not shine, then you should inspect everything where there may be a breakdown. Check the integrity of the cord. Or maybe the contact on the microcircuit has fallen off or the microcircuit itself has burned out.
If this is a Chinese garland, then the easiest way is not to bother and buy a new one. But if you still want to try your hand and repair the product yourself, then we will tell you how to repair the garland. Let's start by checking the LEDs. Then carefully examine how the elements are connected together with the anodes. Next, you need to redo the circuit and connect the LEDs to the cathodes. Instead of the control unit, use a starter from a fluorescent lamp. Here's how to repair the garland yourself. If the resistors heat up during operation, drill a hole on the chassis for ventilation.
Soviet garland
Consider the old Soviet products that regularly serve more than one generation. They certainly just throw away a pity. How to repair a garland of this kind? This is not too difficult to do. With the help of a tester, you need to measure the resistance of each lamp and thereby find a burnt out.
Or try alternately, by means of exclusion, screw the lamp in turn. And since the lamps in the Soviet garlands are screwed in, then it will not be difficult to determine which one does not work. You can apply another method, if you still can not find the source of the breakdown. It is necessary to check the wire for integrity. You will see five soldered wires there. If any of them comes off, you just need to solder it back.
How to repair a garland: some more tips
If you have broken bulbs on the garland, it is faster and easier to change them yourself. But first unplug the power cord. To prevent electric shock, you only need to replace the lamps with the power turned off.
When repairing a garland, if the right light was not at hand, it is necessary to cut off a failed microlamp. And connect the wires manually or with special connectors. Remember to insulate the ends of the contacts!
We present the possible causes of a Christmas tree garland malfunction:
- it is necessary to check the plug, perhaps there are frayed wires;
- the connection of the contact with the lamp holder has broken;
- it is possible that the cause is a blown bulb;
- it is very likely that a fuse blows or a malfunction in the garland circuit itself;
- the problem may be in the controller if the lamps on the garland do not blink and the switching modes do not work;
- We also wanted to draw your attention to the fact that if an LED burns out in a garland, then the entire section stops working. Therefore, when you solder the desired LED, strictly observe the polarity.
That's all I wanted to tell you about how to repair a garland, if one lamp suddenly stops burning or everything, what to do if the board burns out. Now you know how to fix the breakdown yourself, and what you need to do to do this.
