My sling box has worked fine for months and then recently when I go to watch through my Roku, I get a blue screen that says weak or no video signal connected. My sling box is connected with component cables not hdmi, to directv box. The problem is, I really don't understand how to use the remote control. When I initially set it up, which I've done a couple of times, It works fine, the remote works etc. I have always been able to use my Roku box at home in another room, and my roku box at a vacation house. But then It stops working. I can't even check my sling box settings to make sure it's on the same network as the roku because the box doesn't respond. I really don't want to have to reset the box and go through the setup everytime I want to watch news in the kitchen. Does anyone else have this problem? And does anyone know what might help? Thanks!
