I did go ahead and buy two Bluetooth modules (I'll have one for a backup). I replaced the failed module and the Bluetooth connectivity returned. It took me a little over 2 hours to do the replacement, however, I do go slowly and take extra care so that I do not mess something else up. Now that I know how to do it and what to expect, I could accomplish this same job in 30-45 minutes. All I needed was a philips head screwdriver (about 18 screws to remove from the metal back panel and black plastic shroud on the back side of the set) and a thin-bladded screwdriver to assist in prying the plastic shroud off the back. The Bluetooth module was screwed on to the plastic shroud. If your facing the front of the TV, the Bluetooth module is located at the bottom of the set about 4 inches in from the lower right corner of the TV.
