I didn,t know which forum to use for this problem. My orby will not work on hdmi output to my big screen old samsung. First I tryed a different cable without success. Connected it to a small tv I got last year and orby worked on it. tryed original cable and it worked. So tryed the samsung tv with both cables and the hdmi still didn,t work. Next I connected composit from orby to old tv and it works. I only have 3 hdmi imputs on old tv. My trouble seemed to happen after I added the nvidi player. nvida player uses 1 hdmi and my roku soundbar uses another hdmi and I had orby connected to other hdmi. Tryed unpluging all hdmi ports except orby and tv still couldn,t find orby. Tonight I connected my sx88 satelite receiver ant the tv reconized that receiver. So the hdmi seems to work on hdmi from the other receiver but orby will not connect. Do that sound like a problem with the orby receiver or the samsung? Watched a youtube vidio where a guy had an old samsung that one of the hdmi ports quit working. Since tv only had 2 hdmi ports before that one went bad he came up with a new solution. He got an hdmi to vga converter and then he could use his other hdmi equipment. He said it will display 1080 p on the vga. This old samsung I have is a 67 inch dlp with the led projector bulbs and the picture is really good. Speakers went bad so I got the roku sound bar works well but has taken over sound control from tv, and orby. Even if you have roku turned off the remote is still needed to control sound as the volume up and down button still works .
