Hi All,
First post here, so hopefully I present the problem clearly.
I have a string of lights and the controller which makes them flash / dim etc. is broken. I don't like it anyway and would much sooner that the lights were just permanently on... static.
I've pasted an image of the front and back of the board... does anyone have any idea how to achieve it.
I've already looked through previous posts and the link to the australia site showing how to achieve it... but the boards don't look like mine.
Thanks in advance

 

From the picture of the board your lights use a transformerless power supply so it comes under a subject that is not allowed to be discussed on this forum. This is for safety reasons.

The trick here is knowing what was being supplied to the lights you have. Looks to have a Common and 4 lines out likely turned On/Off by the four transistors. Without knowing anything about the lights just looking at the dead board really doesn't say much. Do you have any information on the lights? Were they LED, incandescent or what? Since you have no intention of using the board the fact that it runs on apparently AC mains and is transformer less is really here nor there. The lights it powered are what it's all about.

The set is incandescent. 150 bulbs on the set. On the back of the box is the following info...

 

I get the input part but am not sure how the output is defined. I don't know what the 50 X 5V X 3/0.7W is all about? Hopefully another member will recognize it and come along with a safe power supply scheme who is more familiar with what you have there.

The 50 X 5V could be 50 lamps at 5 volts times 3 would be the 150 lamps.

Nobody uses old incandescent lightbulbs in series anymore. They are guaranteed to burn out soon. When one burns out then they are all out. It is difficult to find which one has burned out.

Take a look at the Power Supply data, what's your take on that? I doubt these are series lamps.

Agreed.

 

Just short out the Collector and Emitter of the transistors, this will put the lights on continuous.
