How to find a problematic place in the chain?

Here the sequence and methodicity are important. As the worst option - you have to check all 54 light bulbs. This is a very long time, especially with regard to the old undivided types of this New Year decoration.

But you can use a faster method:

1. Divide the line into two parts, each of them we call out, thereby determining the non-working.
2. We also divide it into two parts and call it.
3. And so on, until you find the very part that does not work.

Fault repair

Once the problematic element is found, it's time to restore its functionality quickly so that nothing stays on the threshold of the holiday. So, how to fix a garland - sort out the possible problems in order.

One or more colors are missing.

This problem is the most time-consuming task.

Important! If this happens, it means that the light bulbs in this section have burnt out. But for starters it will still be useful to open the control box cover, it's a switch, and to check whether anything is not repaired there.

If everything is as it should be, most likely, you just burned bulbs. The fact is that in a garland all the lamps are connected in series.

Important! Using knowledge from physics, we can say that if at least one lamp in the serial connection fails, then in general the whole branch will not work.

So, when you found the problem, just change the light bulb.

If you have old Soviet jewelry, then it is even easier to repair the garland. Take one bulb 100% working and just screw it in turn into each lamp socket, so you find out which one is not working and replace it.

Do not light at all

To begin with it is worth checking the integrity of the cord, especially if there are animals in your house that like to gnaw the wires. If everything is good here, go to the block and see if each part is well soldered to the board.

Instead of the old control unit, you can use a starter from the lamp at 127 or 220 V. First, check how the LEDs are connected. If it turns out that the extreme elements of the groups are interconnected by the anodes, then you have to rework everything and connect them with cations. In addition, the circuit will have to include more diodes - they will need to pass through a reverse current into the network.

As you understand, this is difficult, so if you understand that the problem is, then it's better to just throw out the old one and buy a new one, it will be much easier.

Light bulbs

No special problems with the repair of the garland in this case is not expected. We replace the old broken light source with a new one.

Important! If you do not have at hand, than to replace, you can simply cut off the old light and connect the wires together in the correct order.

On this, in such ways, you can fix your New Year's decoration and make a pleasant New Year atmosphere at home. But it's better to buy a new one so that in the New Year with new things.
