510 DVR, DP Twin LNB. I started losing channels 140 through 148 (ESPN)about 3 days ago Error code 002. I corrected it the first time using power reboot. Now problem is back. Have done the whole reboot, check switch test thing. No help. In the System Info screen, 119 and 110 clean and green. T4 on 119 and SB4 on 110 both 100+. Call DN tech line twice, got 2 different answers. First time, They wanted to send a tech out for $50, I said wait. The second time, CSR said wait 24 hours and it should be fixed?? Any one heard of this type of problem. I'm suspecting a software issue as signals look good. Again, only ESPN broke, all others ok, including locals.
