Hi there... my brother recently moved to a new place and ordered DTV. He ordered two receivers, a simple HD and an HD DVR. The installer came and everything ok. I visited this last week and while there he realized DTV had quit working. We tried to troubleshoot. First I checked connections and cables all was as the installer had left them. I then decided to check if the power inserter was connected to power and to my surprise I couldn't find one, very strange. Where did the SWM LNB get power from? After looking at all connections and cabling thoroughly his girlfriend arrived and said she had "unplugged" the non DVR receiver from the outlet to put a power strip in place, she needed extra outlets for a table lamp and the strip was off, meaning the H23 receiver wasn´t getting power. We´ll as soon as we turned the strip on, we heard noise from the set at the living room. WOW, the H23 is not only a receiver but also serves as power inserter for the SWM lnb. Not convinced I unpluged the coax cable from the H23 and signal was lost at the living room, reconnected and came back. What a neat surprise, has anyone seen this before?
