@Neil McRae, we have added quite a few mods on to this. We don't normally bother with them and our tables, we're normally stock but ChrisB sorted comets for us on MB and SS after we saw how amazing they make TAF - they make the tables look brand new. However with TZ, we saw such a nice example at Play Expo - we've been aiming for that really!
List of mods below in case it could be power related or anything I could try:
led strip down ball launched lane, slot machine scoop and shooter lane scoop are lit, camera mod, Robby the Robot mod, gumball light mod and led strip for the back box which is currently disconnected as I needed to use J116 for the ColorDMD.
Got the TV on order and the spiral fitted but that's not drawing power
