Thanks for the reply. I have not noticed the switch being warm, but I will pay attention now. It is not an unbearable amount of hum, but slightly annoying and I have to turn the television volumn up a notch or two. I did not want to haul it back for the dealer to check under warranty if it was just me being sensitive to the noise. I will get back to you on that switch warming up after I have it running for awhile today.
