Hello there R Brown,
you can reset your TV back to factory settings and just retune your DTV, its just like when you first got your TV, I see its the LE32R74BD,
All you need to do is
1 turn the TV into Standby
2 press these keys one after another
(info) (menu) (mute) (power)
The TV is back on and you are in the service MENU.
Now press your down arrow key until you get to number 12 on the on screen options,
It’s marked RESET.
Push the arrow key to the right, this will switch off your TV and reset it back to when you first got it.
Turn the TV back on and retune it. its very simple.
You might need to setup the TV custom options if you changed any. like your colour or contrast.
I hope this helps you.
ps please dont touch the other settings in the service menu because you need to know what you are doing to adjust these.
