He everyone, I'm new to the forums but not technology in general. The comcast tech came out a few weeks back to hook up the downstairs neighbor's internet and conveniently disconnected every wire at the distribution box area. I have a vip 722k and the dish off the building has two coax lines coming inbounds. I'm pretty sure there were no unattached wires at the distribution box prior to the cable guy disconnecting everything. From what I can see there may be two diplexers out at the box but I'm confused on how those two inbound coax lines would connect unless there is a 2-1 combination connector? We have one tv in the living room and the bedroom has a coax line running to the tv in which used tv2 through that coax line. But the tv2's coax line ran back out to the distribution box and not directly to the vip 722k. I'd really appreciate a simple how to with connecting things back up. I've only been able to get the Sat1 feed into the diplexer working. I connected the line for tv2 into the uhf port and tried changing the settings with no success on getting it to work. Also, is there a certain sequence on connecting these wires through the grounding block first? Thanks for any help with this. I really appreciate it.
