How i do tv chanel tunig - Panasonic TH-42PWD7 42 in. EDTV-Ready Plasma Television

Hello Ansarielectr, The Panasonic TH-42PWD7 is a professional grade progressive wide screen plasma display. It's not your normal HDTV. You probably already know this. This display requires a component /composite video terminal Board that mounts to slots 1 & 2, or slots 2 & 3. The item number for this component is TY-42TM6Y and can be purchased through the Panasonic support website here for about $270. Once you have this component, you can connect the TH-42PWD7 to a digital HDTV cable box to receive signals. Just make sure you're on the right input signal. Hope this helps.
