So my recently bought Samsung 46″ LED TV (UN46D6050) started buzzing on me today. It freaked me out a little because the buzzing wasn’t quiet or anything, and it continued buzzing even after I turned the thing off! It only stopped buzzing when I unplugged the TV completely. My first thoughts were can I still return the TV for a new one? It’s past the 90 days return policy, but the TV is still under warranty. I could call up Costco or Samsung and see if they can come service or replace the unit altogether. What a fuss!
So I explored other options and looked around. A commenter on this blog said that he had the same problem, but it had something to do with a light with a dimmer which caused some sort of electrical interference with something in the TV. Sounds crazy, but I had a light with a dimmer on it and as soon as I turned it off, the buzzing in the TV went away! Here’s the crazy thing, I could plug this light into any electrical plug in my place and the buzzing in the TV would come back. Not just on the same power bar or same circuit.
The best indicator for this type external electrical interference is despite turning your TV on or off (but not unplugging it), it should still buzz. Then you’re in luck! So if your TV is buzzing, maybe it’s a light with a dimmer connected somewhere in your house.
