A few days ago I took delivery of a OCT 2013 build WOZ and everything was fine for a couple of hours then all lights after board 29 went out. After a reboot they came back on but were flickering random colours (different to the colour displayed by W6 and 29). They will come good and work for awhile then go back to random flashing and occasionally locking on. I've searched everywhere and reseated every connection (power and data) as it definitely presents as a bad connection somewhere. Tried bypassing multiple suspected boards all to no avail. It has the 7.5v boards in it and the previous owner mentioned he'd wound the led voltage supply back to 6 volts on advice from JJP. Is there any possibility this could be causing my problems? Certainly seems like a loose connection but I just can't find one! I do love this game and desperately want to get things sorted.
