Rebuilding a laser ball and noticed that there is a burnt space on the top cabinet swing out led/score board. It is right in the center. I found a pic online and it shows that there is a 5/6 contact pcb board screwed to the center back of this panel with 4 wires going to it. The picture is grainy and it looks like their board was also repaired. I think there are 2 resistors there but can't tell the type/rating. Is this a common problem with these machines and is there a fix with different sized resistors?
Thanks in advance for any help anyone can provide with this.
