Ahh...but that's NOT a cable box. There's no cable involved - it's all done over a broadband internet connection.

Yes, it's fiber optic to the node but it's connected to our old cable line. But I see what you mean.

Who is your internet service provider? It should be using your internet connection, not your old cable line.

They are one in the same. The connection is fiber out to the node in the street and then they splice into the existing coax line (that used to be Charter cable) from the old cable company. I get TV and internet through the coax line that my old cable used to connect to.

Exactly - you're getting internet service over the coax and the set top box uses that internet connection to receive TV channels.

My point is there is no cable company involved unless you're using cable for your ISP service. AT&T Uverse has nothing to do with the cable company or a cable TV connection. You could do the same thing with a DSL copper line.

I think were splitting hairs here. What do you call ATT then? A fiber company? My set top box must be a fiber box then (even though it's connected to coax). Technicaly, they are a phone company, but they have nothing to do with my phone.

We could go on for days. All I know is my TV doesn't work

AT&T is a service provider. Just because there is a coax involved somewhere doesn't make AT&T a cable company. Same goes for Verizon FIOS or whatever it's called. These are competitors to the cable companies like comcast, charter, etc.

My only point was that the set top box is not anything like the typical cable set top box. These IP set top boxes are more like computers - they have an IP address and use the internet to obtain the programming signal. They work with any type of broadband internet access including DSL.

I just want to know if there was ever a solution found the to the DTV connection problem on the Mitsubishi. I have the same television and just recently got an HDTV set top box. I have the Directv H20 box and all I get are lines on the screen when the box is connected to the DTV using component video cables. When I check the input connection type on the tv, for DTV it says RGB, not YPrPb even though I'm using component video cables. Could this be the source of the problem? Any help would be appreciated.

Yes. You need to change it from RGB to YPrPb in the Tv menu IIRC.

If the DVT input had never been used since the tv was purchased, is it possible that those inputs have some corrosion on them? I have lost certain colors several times over the past 4 years through the component video inputs. To fix, I "cleaned up " the inputs by rotating jacks in the plugs several times.
