How to repair Stand alone controller from digital LED wings

Good time for all :)

Few days before, we received message from one of our client. Customer sent us a photo of the controller, from which broke away the wire. This is controller from our Smart led isis wings: Di-led 165.

We try very hard - but they still break off.

We think - how to help? send back for repair - to expensive, shipping cost, in two side, start from 70USD. But controller price just 30 USD...

At the time the customer decided to order another controller, just in case :) This is good news for shipping company - because just they make some profit on order.

In any case, we decided to show our clients how to repair the controller.

For work you need next equipment:

Solder kit
Wire cutter
Parts from the repair kit (thermo-shrink tube)
Lighter
Glue gun
Connecting scheme

Glue gun, lighter, wire cutter, controller for repair, wires and multimeter

Soldering iron, solder and my favorite duck book

We lost all wires: buttons and data output wires. Button have two wires, there is no difference between them, and they can be interchanged. Data output wires have 3 channel:
