Comcast here (again)today.Verdict: there is no way that ONE remote control can be used for my TV. This is the 3rd trip out to do this. This TV is about a year old.
Apparently all 37+ codes Comcast has mean the TV manufacturer is to blame. Thing is this TV worked when it was in a different room with one remote control so I know this isn't the problem.
I am so disgusted but every person has a different solution. This one was going to be $8 a month more, to swap out the black box for a new black box. I was willing to pay it just so I wouldn't have to use one to turn the tv on, and another to change the channel, then back to the first one for volume....
And we can go onto the computer and look at someone's backyard in another country!
I need a cure!
