Before i read through the thread i wanted to mention what my DTB-H260F is doing and see if anyone else has had this problem.
I like the DTB-H260F and the tv guide and always wanted 1080. One day i noticed when doing a scan, no channels found. When my surge protector reset itself one day, i noticed it scanned and found channels. Last night i was enjoying the tv and ota channels(i have cable also) and decided i would do a scan towards Nashville and Evansville. I found no channels again. So i pointed back up north where i get stuff at full 10 bars. Nothing found.
It is almost 1 year since i bought it. I can go and unplug it from the surge protector and line conditioner and see if it goes again but that will get old. Has anyone else had a problem like this and was it any cure? This doesn't always happen, just ever now but when it does, i never know when it will come back on and work.
