The discussion revolves around reattaching a broken power cable to the EK-04 controller for LED Christmas tree lights. The original poster seeks guidance on where to connect the 230V AC power supply after the cable broke off. Responses indicate that the last two pins on the right side of the controller are likely for the 230V power supply, but there is confusion regarding the correct connections due to the presence of multiple LED control circuits. Some users suggest that directly connecting the LEDs to the power supply may damage them, as they are likely designed to work with a controller that regulates power. The conversation also touches on the potential for shorted thyristors and the importance of identifying the correct solder points for the power supply connection. Various troubleshooting steps and technical insights are shared, including the need to check for traces of the break on the board and the implications of incorrect wiring.
