1. I have not experienced fan noise. (Sitting 5 feet in front of TV).
2. My TV run quiet, no buzzing sound. However, it does make strange click sound after I turned off the TV. The sound goes away once it cool down.
3. I do experience how certain dark scene all of a sudden become a bit brighter in THX mode. However, the brightness does not show up on the letterbox black bars (if I remember correctly). There is an option in Custom mode that allow you to turn off the auto brightness compensate, "A.G.C" However, this option is not available for THX Mode. In custom mode, I set it to zero.
Suggestion, definitely make tons of phone call until these issue are being fixed and better do it before your warranty expired. Good luck.
TO ALL OTHERS:
IR (Image Retention) - Yes, my TV have that problem. At least, it will go away if you start playing more fullscreen content.
Burn-in - No, I did not do any of the 500 hrs burn-in thingy, I did watch a lot of 3D content for the past few months, plus lots of gaming.
Custom mode - I calibrate 2D myself (seem to work fine), used James Cameron's 3D setting, with some tweak here and there if need to. Normally, I would just use his wonderful setting, with the exception, I use "MID" brightness.
I don't watch TV.
Yes, this is my first Plasma TV. Taking a risk before 2012. Oh well...
Good luck everyone. ~ Enjoy ~

~First off, the fans: I had a fan
go extremely noisy about a month ago anytime the set was on. This was the center fan, and it basically sounded like a film projector was being run out of the back of the set. I called Geek Squad and they sent a guy out, who agreed the fan was no good. He ordered all 3 new and came back a week later to replace them all just in case. He also pointed out that the fans were actually a new different
part then the ones it came with. Now...about 2 weeks later, the CENTER fan again is starting to get noisy. Especially if the TV is on for closer to 3-4 hrs. I can't figure out how all 3 fans seem to be interchangeable, yet here again the exact same one (even being a different
part) is acting up.
Anybody else hear this??? What do I do? I'll call Geek Squad again, but don't want to jest keep trying the same solution.
~Next issue is the buzzing
that my TV seems to make. It seems to make different volume busses based on the picture changing on the screen. So I thought this was maybe due to signal from my DVR/cable. I tried switching the HDMI cable in case one wasn't shielded, and tried different inputs as well, but to no avail. I've read that extremely bright picture has a tendency to buss, but this is like a different volume buzz every 30-60 seconds while watching regular TV. Also, we didn't seem to hear this until about 2-3 weeks ago and now it's nonstop. Could the fan replacement somehow have triggered this???
~And lastly, I've seen somme posts asking if the TC-P50VT25 has an auto-dimming
effect especially while set to THX mode. The only responses I've seen address the white levels v. the THX capacity for black, etc...but I don't know if this is the same thing as I'm seeing on my set. Even when watching a blu-ray, the whole light level of the picture changes from a deep-black to slightly-lightened (including the letterbox bars) back and forth all through whatever I'm watching any time the scene changes. It's pretty annoying and noticeable, as if someone's turning a light switch on and off in the room while your watching the TV. Is this just how these plasmas work? Am I over critical, or is my set just turning out to be a lemon?
Needless to say I'm really frustrated and upset about the TV. It was an investment for my small income, and though it seemed to be great for the first few weeks- it seems like the whole thing's falling apart on me.
PLEASE shoot me some suggestions, tips, etc...I'm filled with anxiety over this!
