Tests I conducted....
1. Switched out HDMI cable. Same error.
2. Played blu-ray. It works fine but sound only from TV speakers.
3. Samsung SmartHub function seems to work fine. I played Star Trek from the Netflix SmartHub albeit sound from TV speakers only.

I'm assuming either my receiver or my Genie has died and it's not the TV?
Its not the tv

People need to stop freaking over 4K. People will still be able to use their current tv's well into the future. Unless the tv manufacturers strong arm the fcc into making all cable companies go 4K when they can barely do true 1080p, 1080p owners should be just fine over the next 5 years.Blu ray will still be on the shelves just like dvds still are. Plus, are these new 4K televisions going to make everyone throw away the blu's they already own? Cuz I sure as heck aint. Im going to be watching all my movies well into the future.For godsake The Blob 1988 just came to blu a week ago. There is no way ill see a 4K master of that movie for the next 10-15 years, if ever. Calm down and go buy an F8500.

Adding to the buzzing conversation. I just set up my 51' that I received and the buzzing is unbelievably bad. I noticed it right when I started to do the set-up with the all blue screen. It then seemed to fade a bit but once I turned on the PS3 it was audible again. I started watching The Master which has a lot of very bright and very dark screens and the buzz was unbearable on the bright scenes. My wife walked into the room and said "God, that sounds horrible, is that the TV?" On bright scenes you can hear the TV from the entire living room, this is with the volume at 14-15. After a little investigation I found if you press on the back of the rear panel the buzz completely goes away for both bright and very light buzz for dark scenes.





I used a decibel meter on my phone and held it next to the TV. It's not entirely perfect but you can see the first section is a normal light scene that shows spikes when the screen goes white. Seemed to spike around 33db. Then on dark scene you can see the dramatic drop to around 24db. Obviously this is not normal, I hope My guess is this set will need to be exchanged or serviced. I bought the set from Value Electronics so it's not easy to exchange, I also don't know if exchanging for buzzing will result in a restocking fee. The other option is going the route of a Samsung Tech. I just can't imagine this buzz will get better with time.

I would hope that Value Electronics would consider that a defect. Could you respond Mr. Zohn? Tx.

Here is a much cleaner db view of going from a dark to light scene. I'm going to make some phone calls tomorrow. I wish there was a quick fix to just tighten the rear panel. Anyone know why slightly pressing on the top left of the rear panel (where the large vent is) would eliminate the buzz?
