Just want to give a shout out to Frank at JJP tech support.
I recently acquired my first JJP game, an ECLE w/ 7.5 buffered boards. After transport the majority of the lights went out. DOH. Picked up some longer cables and traced it to three big ones and three GI, they were kind of all over the place in the chain.
I was all set to bite the bullet and do the 2.0 upgrade, as six is just too many light boards to replace... but Frank suggested I first inspect the fuse lights in the power board. Sure enough, one of them (F2) was dark, so I followed his next steps and unplugged the power from W1, and F2 lit right up. I then reconnected the boards with just W1 bypassed... everything came back on, amazing.
He also helped me work out a couple other random gremlins, and I'm basically 100% dialed in now. Very impressed with this level of support for an out of warranty machine!
If I'm still as excited about this game a year from now I'll most likely do the kit upgrade, which he graciously offered to lock the current price at should it go up. But for now, he set up an exchange for a very reasonable cost and I'll just swap it out, enjoy, and focus on educating myself on the 300 pages of rules
