Having similiar issues with my game. Purchased new a few months ago. After a few weeks lightts started doing all crazy things. Found one bad data cable. Took over 2 weeks to get from jjp. Just installed the cable and same issue if not more with the lights.
JJP told me i will basically always have some issue from time to time with lights. Boards were designed with a faulty i c chip. Down the road they might engineer a new board set and cable design. Its just an idea at this time.
Back on the phone with them on monday. I have talked to other woz owners that have had no issues. No idea why my machine always have had issues out of the box
