is this tv the same model/brand? far be it from me to claim poltergeists are at work, but who knows... the very first thing i would do in diagnosing this issue is to grab some electrical tape and aluminum foil, tape a patch over the ir receiver for the remote, this should be a shiny piece of black plastic somewhere on the front of the tv, some are marked, some are not.. if you have it, aluminum duct tape works great for this purpose.
to me, it seems like someone is messing with you using a remote, tv-b-gone, or similar product like a keychain universal remote.. if the tape over the ir sensor fixes the issue, i would look at roommates, kids, neighbors, or possible interference from other ir or light sources..
possible culprits would be:
dirty remotes that keep sending a signal with nobody using it
laptops or cellphones with an irda port
palm devices such as palm, clie, etc that have irda
intermittent strobes (emergency vehicles, bad ballast in a light fixture, etc)
i can't guarantee this is your problem, but it seems like it since this is your second tv with the same or similar problem... as a sidenote, the sony clie came with a universal remote program, i caused much chaos in my local video stores by shutting down their video wall while browsing.

SOURCE: channels keep changing
Make sure there is no other remote control working simultaneously or with a key pressed constantly by mistake. In my case i found the air conditioning remote control with one key being pressed by my furniture next to my bed, it was causing that erratic behavior. As soon i realized, i stopped that remote control and problem solved. I hope this works.

Just hold down the input button on the right side of the tv. This is the bottom one. So,
With the tv off,
press and hold the bottom button (input)
when the tv turns on, and you see the input menu
release and press the button to put the tv into a mode that works!

go to menu setup and do the full system reset setup option... Then before you scan for channels make sure it is set to cable... This fixed the problem for me.

You need to isolate the problem.
1) Unplug the set for a few seconds then plug it in.
2) Operate the TV with the control/buttons on the TV. (Channels etc)
If the TV operates correctly then do the following.
3) Try operating with the remote unit. If the problem returns then it's the remote failing.
Sometime remotes can be reset.
Step 1- Pull the batteries out of the remote and leave them out until Step 4.
Step 2- Press and release each and every button one at a time on the remote control until every button has been pressed and released at least once!
Step 3- If your remote has slide switches, you must move the switch to each position then repeat the button pushing in Step 2.
(When you're done, be sure to put the slide switch in the correct position to operate the unit the remote came with!)
Step 4- Put the batteries back into the remote, being very careful to install them correctly.
New batteries should be used if you're not sure about the old ones.
Try it again. If the problem is still there then the remote is bad.
Since this is a new TV you should use your warranty to replace any bad parts.
