I used to get basic channels pretty clearly until recently they all just disappeared. I was reading up and it seems my tuner is no longer working. I have cable internet and that works fine. So, in order to try and get some channels, I bought the Mohu Leaf Metro, hooked it up to my TV, did a channel scan and got nothing. Followed whatever instructions came with it. So, I basically have the same problem as I do without the antenna. I have an HDTV but do not have cable TV service. So, how can I get the Leaf to work? Seems plugging it into coax input doesn't do anything. Would it help to plug it into HDMI input? And if so, I would need the Leaf cable to have HDMI output but it doesn't. What are my options aside from getting a new TV?
