Upon turning on my TV, the channel I was last on (radio 1) works (sound and picture). However, when attempting to change channels, the screen simply freezes and there is no sound. Yet, the menu button still works and I can change my TV onto different modes (on Toshibas: 1,2,3, HDMI1, HDMI2 and PC) yet the channels within DTV will not work. Please help!!!
Try to do a system reset and check if it fix the issue and check below video:
else if the TV is under it's warranty period you can always ask the seller / dealer to fix or replace if it can't be fixed.

I have found the solution at last :)
Put the TV in standby and press these buttons in order
Info, Menu, Mute and Power on.
You will then see a hidden menu, on line 12 select reset
Bingo :)

I had this problem. Unplug it while it is powered on. Worked for me.
SOURCE: need help
ensure the tv is in analogue mode, not dtv and turn it off. with the remote: press info then, menu, then mute then power. these buttons need to be pressed sequentially not all at the same time and in quick succession. a menu will appear on the tv. navigate to the reset option and press the left arrow key on the remote (or press the enter/ok button) the tv will reset itself and turn off. turn the tv back on & it'll re tune all its channels. DTV should be working again.
