Welcome to pinball ownership (in other words, get ready to fix shit). All sarcasm aside though, that sucks and it's sad to hear that you got this on a first time buy. For that price, a "nice" Shadow wouldn't have broken plastics and board hacks like that. The DMD being scrambled is probably just connectors - the rest is a subjective interpretation of cosmetic details. But still. Hope you get it worked out. Don't give up and be disappointed. It will be a fun game when you get stuff sorted out.
