EK-04 Christmas tree lights: Why do only every second LED light up without the driver?

Question

Hello
This problem has already been discussed on the elektody forum https://www.elektroda.pl/rtvforum/topic2166732.html]Link [/url] but I haven't found out everything yet. The lamps are connected by omitting the driver. They shine, but not all of them only every second. I don't know where to connect the two wires that I have left. They are not connected to the LEDs.

everything is described in the topic you entered.

Exactly as you painted. You connect the cable without LEDs to W +.

Each channel is divided into two "strings", probably 62 and 63 LEDs each.

Each of the cables without diodes is W +.

I connected to W + and all the LEDs do not light up

babks131212 · Answer

look at the photo. W + path broken.

I know that it is damaged, so I bridged it with a wire on the other side of the board. If there was no bridge, the lamps would not be lit. My problem is that every second glows, and I don't know why.

oj · Answer

You have damaged one of the LEDs in a row, and every pair of LEDs are also (sometimes) installed 1 / 8W resistors

mekoy · Answer

I thought so too, I found a soldered wire at the end of the lamps. I plugged it in, but still they don't all light up. I will check all the LEDs, maybe I can find some damage.

I have a similar problem, such a PCB, but the problem is that these cables have broken off and I don't even know how to connect it back:

I also have a Gretz bridge if it could be connected somehow.

In general, the point is that it does not flash.

Thanks, mate, it works as it should, but I am scared by the Chinese threads in these lamps.

Jackziom · Answer

And it's strange that she didn't scare you (short) the price of this set.

zerohunter · Answer

These are not my lamps; p

Can anyone help me with these lights? How to connect them so that they shine all the time without flashing?

zyzy52 · Answer

Hello. Show the picture of the whole tile from the side of the elements, then you will be able to give hints on how to connect the bridges to bypass the controls.

lukmos1 · Answer

Here is the plate, please.

zyzy52 · Answer

Connect like red bridges and remove the elements marked with blue circles.

Hi, I have tried this and it is somewhat working. Every second light is on, but the ones in between are off. Any advice on what this could be?

zyzy52 · Answer

See answer # 6. Probably it.

Modification I made for EK-04

Hi,
I have purchased several sets of LED lights (500 pcs) with the E-04 driver and have another board. I am attaching a photo:

.

Could I ask for info on how to modify so that they all light up with a continuous light every time they are powered up?
Thanks in advance for your help.
Greetings
