Hey guys, ltnp here. 
I went to hook my Duo-R up to a different TV today. It'd been a while since I played it (in a Management-in-Training kind of program and busy with life) and was feeling like molesting my Duo Controller a bit today. XD
Unfortunately, I couldn't get the unit to power on. I tried the 9v NEC adapter that came with my Duo-R and a 10v SEGA adapter that also fit (I've only used the 9v NEC adapter since I got it). I tried them both in multiple outlets just to be sure. There are two small kids in the house, so I'm a little worried that they might've done something to magically transform my Duo-R into a brick and/or nice-looking paperweight. Cosmetically it looks fine from the outside and there doesn't seem to be any loose parts.
Any suggestions on how to find out what the issue is? I don't have enough time to take it apart and look at it until tomorrow, but thought I'd post here and see if anyone had a good idea of what to look for.
