Hi. I just bought a new house and am trying to figure out the wiring for one of the rooms. Here is the setup. Coaxial cable comes out of wall into DVR/Cable box. HDMI cable from DVR to a HDMI/Cat5 transmitter box. Two Cat 5e cables come out of that box and go through wall to a receiver on the other side of the room. Then, there is an HDMI cable from that receiver to the TV. I got everything hooked up and working fine as an initial matter, but I seem to run into a problem when I turn the TV off. I leave the DVR on. When I turn the TV back on, all I get is a blue screen. If I go unplug the HDMI cable feeding from the DVR to the HDMI/Cat5 transmitter box and plug it back in, then the picture comes back on the TV. I've been searching online to figure out what's going on to no avail. I'm no A/V expert by any means - I've read some things about issues with the HDMI handshake and making sure you power up your devices in the right order. Is it a simply a consequence of this set up that I can't turn off my TV alone without this problem occurring? Could this stem from the fact that my TV is only a 780p HDTV? Any help greatly appreciated. Thanks.
