How to repair a garland ?

Off One or more colors

One of the most time-consuming breakdowns considered the casewhen Electrogarlands not work one or two colors, for example, only red or yellow, and blue, as in the photo below.This suggests that, most likely burned out bulbs in the appropriate section.

For a start it is recommendable to disassemble the switch cover, it is the control unit, and check all connections are secure - contacts soldered to the board.Immediately offer watch the video lesson from the young wizard, which clearly shows what to do if the broken wire from the controller board:

If mind is all right, then, is likely to be judged that the lamp burns out.The fact that modern garlands are so arranged that all the lamps are connected in series monochrome and if any burn, the light goes out on the entire electrical branch.To repair the damage, it is recommended to act as a good old textbook advises: cut in half garland and ping both sites.Then act the same way with the broken section: cut by 2 and check again and so on until the end, as shown in the diagram.

As a result, you will be able to determine which lamp is not working and replace it.Please note that this repair method should be used in the event that Electrogarlands not folding, usually Chinese.

to quickly fix a garland with their hands, you can take the tester and instead attach the probes on the ends needles.With the help of needles punch successively each of the circuit sections to the needle went up to the current-carrying conductor, and look where the resistance of the section differs considerably.This way you can find the damage and repair it, exerting less effort.

Old Soviet garlands on the tree (without a box) in this regard, more convenient, becausein which all the lamps are screwed into the sockets, and determine which light can not work without a soldering iron and ohmmeter method of exclusion - by taking a working light source and alternately screwing it all the cartridges.The other method of repair - using a tester to measure the resistance of each bulb until you find burnt.

Example repair another difficult fault:

Another way to fix a broken elekrogirlyandu - check the integrity of the common wire.The board on one side you will see the soldered wires 5: 4 for the luminescence of each of the colors and one general.Now, if the total broke the wire, it should be easy to solder.

addition to light bulbs is the reason that in the chain is not lit, one or more colors can be to wire break, just responsible for a certain color.This problem most often occurs if the house has a cat or dog that being played gnaw wiring.In this case, you need to find a place of damage, re-twist the conductors and insulate them.Do not interfere, then to protect wires from pets.

not light up at all

If you have LED string does not shine, and you have seen that it is not a light emitting diode, there is already need to look control unit and power cord.Start by checking the integrity of the cord, it may be interrupted or cut short contact on accession to the chip.Then check how all contact soldered connections to the board.For example, in the photo below one of the wires otgorel.If all workers, burned fee.You can, of course, buy a new garland, if this was a cheap Chinese, but if you want to repair the product, and now we'll show you how to do it.

Instead of standing control unit can be used from the starter fluorescent lamp at 127 or 220 volts (the difference is only in the light bulbs blink rate).First, check how connected LEDs.If it turns out that the extreme elements of the group are interconnected anodes have to remake the circuit and connect the LED cathodes.This is due to the fact that for the normal operation of the starter to the anode voltage must be supplied in 5-watt resistor 15-20 ohms.In addition, the circuit will also include diodes, as shown below.The diodes are needed in order to pass through a reverse current network.That's the way you can alter and thereby fix the LED garland with their own hands at home.

As you can see, it is necessary to strive to repair the product, so if Electrogarlands Chinese, it is better not to waste time and buy a new one.By the way, to alter it under the starter is recommended even if the garland is not flashing or does not switch modes, and the reason for this - the controller.

Please note that if the Christmas tree in the diode lamp is burned out LED, after which the entire section is not lit, the solder-defective item must be strictly according to the polarity!

smashed bulbs

If one or more light bulbs were broken, and you want to repair the product, we recommend to simply replace the damaged light source a new one.Please note that the replacement should be done only when the power is off, so as not to get an electric shock.This, of course, shatterproof lamps better becausethis fault passes them by.

If the hand is not a spare mikrolampy, feel free to cut and connect the broken wires without it.

Well, the last thing I wanted to say - if you have a tube garland (Rope) does not work, try the tester visually and find the problem area and cut it into the ground, intended to cut (marked with scissors).After this working sections are connected by special connectors, on what repairs will be finished!

That's all that I wanted to tell you how to fix a garland, if not lit a single color or burned board.Now that you know what to do to repair the damage with their own hands!
