I recently purchased a 42" Panasonic LCD TV because our 42" Plasma only displays half a screen. I have hooked up our TV according to the guide and have been trying to get our cable to work. When we try to watch TV, we can get one channel up on the screen but the remote will not change the channels. I have followed all the steps to reprogram and lock the remote but it still doesn't work. We have a digital cable box, not the High def cable box kind but the older one that hooks up via cable cables. I have heard that some tv's with eco settings can be an issue. Is this the case? Is there any way to bypass eco settings to watch tv normally again?
