Hi--I am trying to replace a DC50Xu that has stopped working. I've run through all the troubleshooting, and tried to find a way on the Xfinity site to echange/order a replacement but haven't had any luck. Any suggestions?
My DC-50 adapter quit working around the same date. I requested a new DTA-HD box, but still having issues? Is your problem corretced with the adapter box. All my HDTV boxes work fine.
