Here's my problem. For 2 years, I've connected my Samsung HDTV to my Sony Vaio laptop the exact same way using the exact same HDMI cable without a hitch. Last week I moved to a new apartment, I plugged the HDMI cable into the same port that I always use, and all my TV does is blink 'no signal'. The move was very short (< 5 miles) and I carefully moved all of this equipment myself, so I know nothing was dropped or mishandled. Any ideas? Is there a setting on the TV that might have gotten fudged when I unplugged it (I doubt that this TV has been without power the entire time I've had it)? I just don't understand. Everything worked out of the box the first time, and every time without a problem until now.
