The RCA BD20TF10 was manufactured before digital tuners (ATSC) were required. It only has an analog (NTSC) tuner so you will need a digital to analog converter box to watch most local channels. (These were the boxes available with the discount coupon as the ATSC broadcast transmitters were enabled.) Depending on the converter box model, use either the composite video input or use the RF antenna connection. If you use the RF output from the converter, you will need to set the TV to channel 3 or 4 (set the switch on the box to match). Then follow the directions for searching for channels with the converter box.
You may be able to find a low power analog station still broadcasting. However, you'd need to be close to the transmitter or have an antenna that is rated for a long-range signals. (Usually this will need to be an outdoor antenna with few obstructions between the transmitter and the antenna.) To scan for any available NTSC channels, make sure that the TV is set to TV mode. Then press Menu. Use the Up/Down arrows to highlight Channels and press OK. Select Auto Channel Search and press OK. You may need to confirm this step by highlighting the Start Search option and pressing OK. This will also let you add the appropriate channel for watching the signal from the converter box with the RF cable. The manual for this TV is available from Sears Parts Direct here: http://www.searspartsdirect.com/partsdirect/user-manuals/BD20TF10-Rca-Parts-Television-Parts-manual . The direct link to the manual is http://c.searspartsdirect.com/mmh/pd_download/lis_pdf/OWNM/L0312126.pdf .
I hope this helps. I'm not sure if the Menu feature is available from the front panel buttons. You may need a remote with a matching code to do the channel scan.
