I just purchased a 40a650 today and unfortunately, I am already experiencing a couple of problems. After my tv has been on for approx. 5 minutes, my remote no longer works, even though the tv light turns on as though it is receiving a signal from the remote. In addition, the volume goes off and is replaced by a loud, intolerable, buzzing/humming noise.
If I unplug the tv, wait a few seconds and plug it back in, then it works, but only for about 5 minutes or so and then these problems start all over again. Has anyone else experienced this?
I called customer service and they are sending a technician - they think it might have something to do with a firmware update that was installed.
