It is simple. Either connect an HD OTA antenna directly to the television antenna connection or update your satellite or cable service to HD service. I am using an Over The Air antenna and have a perfect picture.........for free!
what the other guy said is true, the tuner in this thing is awesome and my broadcast stations are quite superior to the same station on my digital cable. and i live in the middle of nowhere, it has great range
It is really not the TV that limits your viewing, but rather the signal your set is receiving. When stations converted over a few years ago, I remember that viewers were offered special antennas/converters so that they may continue free reception ... otherwise, you must upgrade your cable service to digital.
I have comcast cable. I have wifi built into my tv. It is a sharp. I bought that because I wanted netflix. I dont know how I ended up with cable tv, but I have looked into getting an antenna that fits on the back on your set.
