OK . . . we are back out at Blue Mesa (Colorado) and hooked up the cable . . .
Worked great in the bedroom . . . but bad in the living room!
First off, I bought a brand new coax for outside from the campground feed . . . and I ran it from the bedroom connection directly to the living room TV and I got a perfect picture in the living room!
So I hooked everything back up the way it was, then put the new coax up to the campground feed . . . no better!
I opened up the basement wall again and investigated the spliter behind the wall, and it was indeed hooked up backwards!
The cable outlet on the basement wall for the outside TV was connected up to the input . . . and the outside cable connection and the coax to the living room were both hooked up to the output of the spliter.
I just removed the spliter and bypassed the basement TV connection (since we will probably never ever use it) and put a connection post between the other two so I have a straight line to the living room.
Still . . . a bad picture in the living room . . . a little better but unwatchable!
I replaced the coax from the TV . . . still a bad picture!
Now, pulling my hair out, I had a realization!
A few weeks back I had pulled out the Fusion stereo/DVD player to unroll the diapole radio antenna, and I discovered that it was hooked up to the roof antenna!
Hmmm, I wondered . . . I'll bet there is another spliter under there!
And there was!
I pulled the stereo out of the entertainment center, and when I unplugged the stereo's coax from the splitter . . . the picture became immediately better . . . but still not good enough to watch!
I replaced the coax into the spliter and it seems that the plug-in on the back of the stereo is defective (another thing for the list of warranty repairs), so I just decided to leave the radio out of the mix (even in our side yard in the Denver metro area I was only pulling in a couple of FM stations, so I guess that should have been a clue).
I fiddled around with the spliter and connections, then decided to just remove the spliter altogether!
I put a post between the two and got a much better picture . . . almost as good as in the bedroom!
However, both of the screw-on coax connections there seem to have shorts at the connector and I had to bend the wires just right to get the good picture and then carefully put the wires and stereo back into the entertainment center
so that we can watch the Bronco's beat Oakland today!
So, it turns out that the wiring job from the factory was bad . . . and perhaps the built-in stereo is bad as well!
I hope I didn't ruin our OTA reception as there are no OTA stations up here in the mountains so I can't check to see if that is still working after all of this wiring fanigiling!
