Hi Matt;
Failure of direct injection reds is not uncommon, but it's usually due to back reflection. I don't think that applies in your case though. Still, it sucks that you've got to go through this. (And here we have yet another example of why it's a bad idea to buy a LaserWorld projector... Sorry it had to be you pal.)
Regarding your show in May... Don't sweat it. If you can't get your reds repaired by then and you don't have your new box ready, then give me a ring and I'll hook you up. I've got a spare pair of Maxyz modules here that are part of a larger project that is currently on-hold. So you're welcome to borrow them for your show if you need them.
Adam
