I have ensured the software is updated, changed the audio out to PCM (not Dolby), reset SmartHub, and removed each HDMI and USB connection to test; but the TV continues to buzz. It buzzes in every situation (e.g., when I play a video (Bluray that has surround sound), when I'm streaming, in SmartHub mode, with and without connections). It is connected directly to my Internet router (wired), but it still buzzes when I remove the connector and use the wireless feature.
It was working fine for the past 6 years. Then, all of a sudden started buzzing. At first, I could watch TV and stream for a couple of hours before it started buzzing. Now, it buzzes as soon as I turn on the TV. Should I just give up and purchase a new TV, at this point? Is this one at end-of-life?
There were no new devices in the room when the buzzing began; neithere were any new devices added to the circuit breaker. I didn't replace any cables, but I removed the TV antenna (that included an amplifier that plugged into a USB port) and replaced it with a rabbit ears antenna that only had a connector for the antenna input port. I also moved the HDMI cable for the surround sound Bluray player from port 4 to 2.
None of these things seemed to stop the buzzing while the TV was still on. I turned it off and back on the following day (today) and NO BUZZING. So, to be honest, I don't really know what actually stopped the buzzing, but the TV has been on for 3 hours, so far, without any sign of buzzing. So, it could have been one of the things that I did or a combination of everything. I'm just hoping that it lasts.
