@nomar , I'll bet that's a Vizio issue. We have a Vizio in our eat-in kitchen area and it takes far longer to turn on than any of our other TVs (Sony and Samsung). I don't have my universal remote connected to that TV, but I note that the universal remote also has its own delay, and I'm guessing that the combination of that and the excessive Vizio power-on delay might lead the issue you're experiencing.
I have a very good MX-880 universal remote that
was fully set up and programmed for me, at an overall cost that was so ridiculously high that I forced myself to forget it once I agreed to buy it. Just yesterday we had all of our Comcast cable boxes replaced and upgraded, and the guy who came to install them said he doesn't mess with the high end universal remotes because he'd just screw it up. Now I am pissed because I have to go back to using two remotes for my main TV until I figure it out, which in my case probably means begging the guy who installed my whole system to let me pay him $50 for him to send one of his workers over my house to do it for me.
I'm over 40 and I love it, but I don't think I can figure out how to program it. Unless...someone out there in Boneyard Nation knows and can post a tutorial?
