Cableman says home wiring "old"

Jun 11, 2009 12:30AM PDT

Recently purchased a new HDTV and upgraded to digital cable. I'm not pleased with the picture at all. It's not bad, it's just not as crisp and clear as I think it should be in comparison to every other HDTV I see. I did everything I knew to do before calling the dreaded cable repairman. He says that the wiring in my home is "old" (ie, about 20 years) and won't support the newer digital pictures. I think this is hogwash, but I'm not certain. Please help!

I've seen that affect digital cable.

At least I only had to run a fresh line from the demarc line to the cable box. All fixed now. Be sure to not split the signal if you can.

In some cases it's the real sticking point to getting a clean/adequate signal in your home on equipment which otherwise would give you incredible PQ. My cable guy got rid of several splits and some older coax I hadn't been previously aware of that was plain crap-ola to put it nicely Wink. With a few DVR box swaps after that, we are finally up to snuff w/ Comcast.

That said, there is a wide variety of HD content provided, all of which does not look that good per se, regardless of whether or not you have a bargain basement plasma or top of the line Pioneer. What I am trying to get at is that the presence of an HDTV alone and HD cable box might not mean you see an image that you are totally pleased with. Did you have the HDTV calibrated yet? How is your box connected to the HDTV?

Wiring, Connections, TV, Oh My

You said "the wiring in my home is old". Are you referring to coax cable? If so, that should be a simple exchange for RG6, and make sure you get it with aluminum sheathing, not copper. This coax is VERY cheap and it should be simple to run it from the connector wher the main cable comes to your house, then into your TV. It's not as though coax runs throughout the house like electrical wiring.

You also did not mention how you have your cable box connected to your TV. If you connect by any means other than HDMI or Component then your TV picture will look terrible on an HDTV.
