Oh, and the TV remote does not function with my DirecTV receiver at all now. I deleted the STB from the Universal Remote menu and tried re-adding, and now it wont program at all. I go through the 10 tries and it doesn't work, then I search for the model number (which it finds) and it still will not program. Very strange as it was functioning yesterday.
I am sorry to hear about your plasma buzzing. I have checked out 3 different samples of this model, and 3 of the step down model F5300 in 3 different stores. With my ear 1 inch from the TV, I could not hear any buzz. I am very interested in this TV. And, I have very good hearing. So, I have done a lot of research into this buzzing problem, because I do not want it. I also have a good amount of audio/home theater experience, from trying a ton of stuff in my home.
I will suggest a few things you can try to get rid of the buzzing problem. I wish to say that I cannot gaurantee they will work. I also do not intend to start a debate about AC power, wiring, etc. I am only trying to help. I have no wish to debate or defend clean VS dirty power, or cable differences. You win! I just want to offer a few suggestions, that based on my experience with AV gear, might help.
Have you tried plugging the TV in different wall outlets? If your TV is plugged into an outlet that shares a line with certain noisy machines, (air conditioner, fan, fridge, etc.) those machines could be sending noise into the line. This noise might be picked up by sensitive equipment within the TV.
Are you using an AC extension cord? The cord might be of bad quality.
Is the duplex (power holes in the wall) covered in paint? Sometimes when people paint walls, they roll over the power sockets (not necessarily you, but the previous owner/tennant). You can still plug into it, but the paint will affect the contact between the plug and electricity. This bad contact can affect your gear.
If you are willing to spend about 50$, buy an upgraded power socket (duplex). I bought one from PS Audio. I was very skeptical. It improved the sound, but also improved the picture on my HDTV. It was like my HDTV had been cleaned with Windex; a big difference. I told friends, who also tried it (it's only 50$). They all got the same results.
Also, you can try a power bar that filters noise. In my experience, they do make a difference.
I wish you good luck, and sincerely hope you can fix this problem!
