Quoted from Drac:Thanks for the feedback. A replacement isn't necessary as I can repair them. The LED panels are actually attached by small solder points not by screw.
I really shouldn't have posted this. It was just out of annoyance as I used doubled sided tape to fix the last two panels and then next time I powered the games on I noticed that the panels weren't properly aligned (tape wasn't holding them properly) so now I have to do it all again.
All good; I'm happy to move on. I love the ColorDMDs and would buy from them again. Thanks for the feedback guys.
Looks like someone else has had this problem now too. Nothing wrong with alerting others of the issue. But would suggest alerting ColorDMD also.
