The channels do not lock on my Samsung LN-T4061 40" flat screen. They just keep rolling thru every channel. I have tried cleaning the buttons on the tv and the remote but it does not help.

You should contact Samsung service to know if the internal setup for the picture sizing was not adjusted properly at the factory.

Take care that some of these sets have a user zoom mode. Maybe it is in the zoom mode. Check in your instruction manual before calling for service support.

This looks to be a good hint. After reading the solution "I had the same problem. The fix is actually very easy. Just re-tune your channels in and your remote/channel buttons should work again.", I checked my remote and saw that there was a sliding button "TV/Cable" and it was on "Cable"

I moved it to TV and it started working.

This could be a dumb solution but just wanted to suggest...

SOURCE: Channels will not change- 42

it means that only one channel save from your tv. press automatic search to search more channel from cable signal. now you can change channel.
