I have a Mac Mini mid-2009 model, and I bought a Mini-display port to HDMI adapter to hook it up to my LED TV. I have used it over more than a year with XBMC with no problem. Now, yesterday I unplugged the Mini-Display to HDMI adapter from my Mini because I needed the adapter for a presentation on my Macbook Pro. Now when I returned home and plugged everything back as it original was, the HDMI output stopped working! TV says No Signal. I checked with different HDMI inputs on my TV. none worked. I hook up my Macbook Pro with the cable and it works.. So is my Mac Mini suddenly broken!?
