Your RGB led has a busted R. New led needs to be put in. The LED has three actual points of light in red green and blue that light up in different brightness to create the illusion of infinite colours. The blue and the green are still working hence some colour sometimes, but without the red component it will be the wrong colour.

I had red die in one of these games recently so I put a 555 socket in and soldered a wire from the r on the board a the ground on the board. Put a red flex led in and you can't even tell its not the same board it was before. Just a thought for anyone that wants to get up and running without waiting on stern only parts.

This is no issue!
This insert is for the Black Hole target. It's lightend when you hit all the 5 little red targets and awards a mystery.
When it's lit, it has this light blue. I hope they change this in upcoming softwareupdates. It annoys me from the beginning, cause it's very hard to notice if it's lit, especially in multiballplay...

oooooops, sorry...

I have had 2 boards do the same thing. 2 different boards both with the red out on the board mounted color changing chips. Seems to be a manufacturing defect in some of the boards

Had same issue on 2 boards, mission and weapon one. Replaced boards in warranty.

Unfortunately for me they were not very helpful in that dept. They said the game was more than 90 days and it was out of warranty. He suggested I call my distributer to order the parts.
