How do i get regular tv channels no cable or direct tv. I have a 32' magnavox model #32MF338B/F7

Hello
I'm not sure about the model number of your TV, as here it is marked as both "27MS343S and 32MF338B/F7". Anyway I gies this solution as for the first denoted.
Insert antena to the antena socket at the back side of your TV marked as 75Ohms antena input.
[1] Press "Menu" button on the remote control handset to display menu on screen.
[2] Press "Vol+ or Vol--" button repetedly to hilight "TUN" [Tuner].
[3] Press "Ch+ or Ch--" button to hilight 'AUTOPROGRAM"
[4] Press "Vol+" to programming tv channels.
Tv will tune and store channels transmitted channels at that time, through entire bands, and will display the first channel receved after tuning process completed. It may take some minutes. You have to wait it to complete. After displaying the first channel, you can select your favourite channel Using CH+ or CH--" buttons. Ok.
