Hi, I have a Panasonic PT53X54J and a Sony KD-27FS170 in my home! I use Homeworx digital antenna to run my TV. Thats the only equipment I use While my Hisense F42K20E work quite fine, both Sony and Panasonic TVs are just not showing any channel.. I have learnt that Sony KD27FS170 might need a digital converter box since there are no more analogs tv... But what about my 53 inch Panasonic PT53X54J, how do I make it work?what equipment do I need?
