Hi All, Just brought home a 2010 Rockwood Roo 21SS. Began setting it up etc. Had both the radio and CD working on the concertone no problems. Bought a 22" flat screen and hooked it up and scanned antenna chanels. No problems. Thought it was time to test the DVD. Inserted disc and an error returned on tv and concertone returned "no disc". Tried different DVD with same result. Thought I'd step back in my troubleshooting and tried a CD. Now the CD returns "no disc"!! Thought about disconnecting all pwr including battery but have not done that yet. Any help out there?? Love the trailer but, this has got me really PO'd.
