I know that sounds strange...BUT, when we put the TV on one channel, it seems to go through all of the channels (while staying on the same number). I.E. I'll put it on channel 10, and it will stay on channel 10 (per the display), but will go through all channels, fading from one channel to white noise, then to the next channel for a few seconds and so on.
We've tried autoprogramming, we've tried unplugging the set.
Any other suggestions?

I could be wrong, but it sounds like the TV hasn't gone through channel setup. You have to do this in order for the TV to "learn" the channels, assuming you are using cable. If you are using cable run channel search in the setup menu and see if that changes anything. Can you change channels by manually entering in the channel # and hitting enter?
Lots of possibilities. If you are using the remote, try also using buttons on the TV to change channels. If TV buttons work, the remote is broken or perhaps try changing batteries and cleaning battery contacts on the remote. If neither work, lots of other things to try. You may need to set preselect channels, so your TV thinks there is only one channel out there until you do. If you are on a cable box you just need channel 3 and change channels on the cable box. I can't tell what you mean by "audio changes with the channel" ... if you mean that when you try to advance channels, it increases volume and moving down in channels lowers volume that would be strange -- if you are using a programable remote it might not be set correctly (try another programming code). The "blurred" picture is probably symptomatic of having the set on the wrong channel, and if you could set channel it might clear up ... I'd start with getting channels to change. If you need more help, give the brand and model of TV, say if you are using a remote (original or programable), and what the 'audio changes' comment means in more detail. Probably worst case is that your tuner circuit is fried, but don't assume that without more diagnostic.
This actually sounds more like a signal issue on the cable box. When you go from regular digital chs to HD channels sometimes boxes will distort or pause the picture when changing channels (it's not the cable or satellite, it's your TV trying to read the different format of the chs) this is normal. Also, some TVs may need to have a firmware update and you can normally get it from the Manufacturer's website
go into programming mode and search for channels it will do this automatically to find all antennae and all cable channels if this is hooked up to a receiver box then only channel 3 will be found or used also most tvs are computerized these days and at times it will need to 'rebooted' unplug the power and wait 10 seconds and plug it in again this may have to be done whenever you are locked out from changing channels or using the volume controls
Do you know where your remote is?I have had it where it would do that for days and then I would find my remote was wedged into my chair somewhere and when I sat down it would press a button.Either that or check the wires in the remote and TV.For the changing channels do you look at your remote when you press buttons to switch channels?There is a common button,which,when pressed,will surf through all of your tv's channels.
Had the same problem, channels would not stop scrolling.
It was as though someone had there finger on the channel up button.
Disconnected the sixth wire, starting with the black wire on the wiring harness for the front buttons, on/off, ch. up/down, vol. up/down, etc.
It works fine, no more unwanted channel surfing!!
