Hi,

I have some Christmas lights that came with my tree that alternate different colors. My wife wants it to only light up in white. I opened up the plastic cover for the Circuit board and found the attached. Please could someone help me by letting me know how to alter the board so that the LEDs only light up in white.

 

Welcome to AAC!

I'm not sure what you expect us to do with a picture of a circuit board.

Tell us about the LEDs. Is white formed by using red, green, and blue LEDs turned on at the same time? Or is white a separate LED?

Then we need you to trace the circuit board and make a schematic.
