About six months ago, the HDMI port on my Samsung LCD stopped working. I noticed that it was missing the screws that keep the HDMI port secure when plugging or unplugging a cable.  Since it was out of warranty and the cost to repair it was insane, I ripped it apart hoping I could fix it. I was amazed at what I found: the whole HDMI connector was disconnected from the board!

If you are good with a soldering iron, you can reconnect it, but if there is any doubt you should probably take it to a professional. If you decide to do it yourself, make sure you use low heat and a lot of flux.

After resoldering it and making sure it was screwed in properly, it worked perfectly. Hopefully this will help somebody save some money.
