Had to replace almost all my boards in the first year and 6 more in the second not under warranty. never had to replace a big one luckily. I live in texas somewhat near the coast and its humid and hot even in the winter. I think my issue was since it was on route I did more maintenance and cleaning (plus it was on carpet which probably didn't help when I did maintenance). The tech told me to go with wizards mist and shine, and now anytime I touch the game I put a static bracelet on especially if I'm on carpet. haven't had an issue with those damn light boards in almost a year ( assuming part of that reason is because it's been at home with me for the last six months. the game is on tile with rubber stoppers.)
I'm probably wrong but I thought all the 2.0 system did was let the rest of the game lights remain uninterrupted if one failed. I would assume you would still have to replace the same amount of messed up boards unless they went with more robust electronics. (less prone to static)
posted another topic about the 2.0 system and LTG said if they did release a kit it would cost around 2k. Those were estimated costs, but I'm hoping if someone actually wanted to update their problematic WOZ then maybe they would subsidize the amount. Since in my opinion they should of addressed the issue way earlier then they did. The RR's with the 2.0 system must of been really late in the game mine is #eight hundred and sixty something. sucked should of done my homework. Still happy I purchased the game though.
