Thanks, I will look into those links. As of last night, with both TV's off, we started to watch some TV from our main TV and of course, like the previous night, I was only greeted with the Component source and black screen. I walked over to the Colby and unplugged the hdmi cable and as soon as i did that, the picture appeared on the Samsung. They recommend that I use AWG 22 or 24...hdmi cables with either of those products. I looked at my 15' cable which does work, but its covered with a light blue covering and no identification is on it, except the name of the company, I think ..."Insten" gold plated. The other two hdmi cables I have only one has a AWG number which is 34...the other just says AWG without any number.
