I have a dish625 dvr. Went on vacation and when I came back when I have it on dual mode only one tv is working. The other says finding signal 015. We got back Saturday night. Everything recorded on both tvs up until Friday night and stopped on Saturday before we got home our Saturday night shows didn't record on tv2. If it was the sattelite I'm sure the one wouldn't be working. Also I can get the other tv to work but then tv 1 dosent work. It's one or the other but just won't work at same time. I've checked all of the connections and tried restarting. I'd call a technition but my landlord is running my house and his nextdoor off of the same house and I don want him to get in trouble. I bought the dvr off the Internet sealed in pacage but I'm pretty sure it's referbished. It's worked fine for 4 months. What could cause this problem?
