I have an old Mitsubishi...been working perfectly on Cox until 2 weeks ago. No the Video Output Resolution will not stay on 4:3, 480p SD...keeps changing to 480i.
If I have to change/buy a new TV...I will want to change my service. I'm sure this is a COX issue.
I wonder if HD channels would output ED video to an analog TV? For example, channel 1005 is Fox HD and 5 is Fox SD (480i). There was a channel realignment recently. Try the less-than-1000 version of your channel number.
Just a stab.
If you're noticing discernible 480i, I think you've got a few more years left on your Mitsubishi. You'd know if your tube was dying because they slowly die. That was the good thing about analog: they still worked with screwed up signals.
When I had my JVC tube (22 years!) connected to my digital cable-box, the screen height kept getting shorter and shorter. Time to research a new HDTV. It lasted another month until the video collapsed to just a bright white line across the screen.
